Backlighting the large-scale structure with the cosmic microwave background
Event Information:
Upcoming large-scale structure (LSS) and cosmic microwave background (CMB) experiments offer a unique opportunity to turn the Universe into a particle physics laboratory and determine the nature of dark matter, dark energy, and the masses of the neutrinos. I will present innovative methods to jointly analyze these datasets and unleash their full constraining power. My research explores two powerful ways of using the CMB as a backlight for the LSS: revealing the invisible dark matter (gravitational lensing) and baryons (Sunyaev-Zel'dovich effects) via their shadows on the CMB. These methods will yield percent-precision maps of the dark and baryonic matter on cosmic scales, from combinations of CMB experiments like the Atacama Cosmology Telescope, Simons Observatory and CMB-S4 with LSS experiments like the Dark Energy Spectroscopic Instrument and the Rubin Observatory. These will not only shed light on dark matter, dark energy and the neutrinos, but they will also constrain models of inflation and transform our understanding or galaxy formation.

Watching a Star Explode with the Young Supernova Experiment
Event Information:
We present multi-wavelength observations of supernova (SN) 2020tlf, the first normal type II-P/L SN with confirmed precursor emission, as detected by the Young Supernova Experiment (YSE) transient survey. Soon after discovery, "flash" spectroscopy of SN 2020tlf with Keck LRIS revealed prominent narrow emission lines from shock-ionized circumstellar material (CSM) shedded in progenitor mass-loss episodes in the final months before explosion. Following classification, SN 2020tlf was observed in a thorough multi-wavelength follow-up campaign (x-ray to radio) out to 300 days after explosion. The nebular phase spectra of SN 2020tlf constrain the possible progenitor masses to 10-12 Msun. Finally, we present radiative transfer modeling of the SN light curve and spectral evolution, which reveals that the progenitor star had an extended envelope, detached CSM and a heightened mass-loss rate. We will discuss how the progenitor and CSM properties of SN 2020tlf fit within the phase space of the small but growing number of SNe with "flash" spectroscopy and pre-explosion eruptions.

Messy, Soft and Squishy: The Complex Biophysics and Mechanobiology of Living Cellular Systems
Event Information:
Abstract: The Pelling Lab for Augmented Biology is a highly interdisciplinary research group in which there is a seamless flow between fundamental biophysics, custom instrumentation, material science, bioengineering, tissue engineering, in vivo animal trials and commercialization. In this talk, I will speak broadly about our efforts in developing an understanding of the intimate relationship between Physics and Biology. Our work, and the work of many research groups worldwide, has described a profoundly important feedback loop between physical phenomena and biological behavior and function. But the relationship between Physics and Biology extends beyond a living system’s ability to simply “respond” to physical information. Rather, physical cues also impart evolutionary selection pressures, which have optimized the operational principles by which molecular and cellular systems function at small biological length scales. My lab focusses on how we might exploit the physical characteristics of the microenvironment to understand the mechanisms through which cellular systems sense, transmit and interpret physical cues. Such physical cues can include highly diverse pieces of information, such as the rheological properties and geometry of the microenvironment, as well as the presence of anisotropic and time-variant mechanical stresses/strains that exist within the microenvironment. We are also beginning to utilize such physical phenomena to take control and direct the organization and function of living systems in extremely artificial contexts. For example, our recent work in developing unconventional plant-based biomaterials with unique structural and viscoelastic properties which influence the growth and regeneration of living tissues. Researchers in the Pelling Lab thrive when operating in the interstitial space that exists between disciplines. Over the years our work has led to new fundamental and applied biophysical knowledge, novel devices and quantitative methodologies, commercial partnerships, and the formation of multiple healthcare and biotechnology startup companies which are translating our work into the clinic and marketplace. This talk will be structured with a broad range of scientists in mind and my goal will be to leave the audience with an appreciation for the deep connection between Physics and Biology, an understanding for the open questions in our field and why it is important to fill these gaps in knowledge.
Biography: Andrew Pelling is a lifelong scientist, full professor at the University of Ottawa and founder of multiple start-up companies. His highly experimental Pelling Lab for Augmented Biology has trailblazed by developing speculative living technologies of the future with the potential to redefine the limits of biology and medicine. The Lab is well known for its discovery that plants can be harnessed to create medical grade biomaterials for engineering and regenerating human tissues. To date, the Pelling Lab has spun out five companies in the technology, biotechnology and medical fields, translating their discoveries into real-world products and solutions. Pelling also serves as co-founder and chief scientific officer of Spiderwort, a company translating the fundamental discoveries from his Lab in the area of plant-based biomaterials. As CSO, he leads Spiderwort's research program, which addresses a variety of tissue engineering applications and unmet medical needs. He also plays a key role in guiding the translation of Spiderwort's products through the clinical and regulatory landscapes. Pelling has been well recognized by his peers and is the recipient of numerous grants and awards, including being elected a Fellow of the Royal Society of Biology, Member of the College of the Royal Society of Canada, TED Senior Fellow, Raine Medical Research Foundation Professorship, NSERC Discovery Accelerator Supplement, Province of Ontario Early Researcher Award and a Tier II Canada Research Chair.

First Constraints on Reionization from HERA
Event Information:
The eras of Cosmic Dawn (when first-generation stars were formed) and reionization (when first-generation galaxies systematically ionized our Universe) are rather mysterious epochs in our cosmic timeline. New radio interferometers promise to change this by mapping out spatial fluctuations of neutral hydrogen at high redshifts via the 21cm line. In this talk, I will discuss recent upper limits on the high-redshift 21cm signal set by the Hydrogen Epoch of Reionization Array (HERA). I will explain the science implications of these limits, particularly how they are already putting constraints on the X-ray emission of first-galaxies. Additionally, I will discuss how these relate to other observations of the high-redshift universe, and highlight future science opportunities with HERA and similar instruments.

Development and characterization of a Penning ion source using helium
Event Information:
Penning ion sources are an old technology that have been overtaken by Electron Cyclotron Resonance ion sources in the production of high current high-charge state ions, such as for alpha particles. However, Penning ion sources are relatively cheap and compact ion sources, and therefore could be used in medical accelerators which require high current alpha-particle production. To be able to optimize a Penning ion source for high current alpha-particle production, one first needs to be able to characterize and understand the plasma dynamics within it under helium operation. For this reason, a test stand and prototype Penning ion source is developed which allows for the confining magnetic field, inlet helium gas flow, arc voltage, and extraction voltage of the ion source to vary. This thesis describes the design and engineering of the Penning ion source using helium gas. In addition, plasma simulations using COMSOL Multiphysics are used to model how this ion source responds to various input parameters, and diagnostics tools such as optical emission spectroscopy are used to measure the plasma properties as these parameters are varied. The later was done by creating a collisional-radiative model which compares well with Yacora on the Web from IPP Garching and improves upon it by adding radiation trapping approximations. The optical emission spectroscopy diagnostic is compared to Langmuir probe measurements in a TRIUMF-licensed Volume Cusp ion source to verify trends observed using this diagnostic. It is found that the plasma simulations and optical emission spectroscopy diagnostics agree on observed trends of electron and ion density for each varied operational parameter. This is confirmed by observing the same trends when extracting the ions from the ion source. However, it is clear that the non-maxwellian behavior of electrons can have a significant effect on plasma dynamics, which cannot be resolved with the current diagnostics or plasma models. Thus future studies will need to be performed to analyze the electron kinetics with the plasma to better determine how alpha particle density changes as a function of the various input parameters, and thus how to optimize the ion source for alpha production.

Passcode: 113399
Speaker: Jennifer Cano, Assistant Professor at Stony Brook University
Title: Higher magic angles in twisted bilayer graphene and topological twistronics
Bio: Jennifer Cano is an Assistant Professor at Stony Brook University and an Affiliate Associate Research Scientist at the Flatiron Institute. She earned a PhD in physics from the University of California, Santa Barbara, in 2015, and was subsequently a postdoctoral fellow at the Princeton Center for Theoretical Science. Her research is focused on the classification and realization of topological phases of matter, ranging from strongly correlated phases with fractionalized excitations to non-interacting topological band structures.
Abstract: We present recent analytical and numerical results on the chiral model of twisted bilayer graphene and introduce a new platform for twistronic devices on the surface of a topological insulator. In the first part of the talk, we study the flat band wavefunctions of chiral twisted bilayer graphene at higher magic angles. We show that at higher magic angles, the wavefunctions exhibit an increasing number of zeros, resembling quantum Hall wavefunctions at higher Landau levels. Zeros of the same chirality cluster near the center of the moire unit cell, causing an enhanced phase winding and circulating current. The wavefunctions at higher magic angles have signatures in scanning tunneling microscopy and orbital magnetization experiments. In the second half of the talk, we investigate the fate of the surface Dirac cone of a three-dimensional topological insulator subject to a superlattice potential. Using a combination of diagrammatic perturbation theory, lattice model simulations, and ab initio calculations, we report a dramatic renormalization of the surface Dirac cone velocity and the formation of gapless satellite Dirac cones. The latter can produce very flat bands that may be a fruitful place to searching for interaction-driven physics.

A Chemical Toolbox for Astronomers – What molecules can teach us about our universe
Event Information:
Less than a hundred years ago astronomers believed that molecules could not survive in the harsh environments found in interstellar space. However, advancements in radio astronomy in the last 50 years have enabled a boom in the detection of new molecules. Today, our picture of the molecular universe has expanded and around 250 molecules have been identified in the interstellar medium, including exotic and unstable species as well as many molecules that are also found on Earth. These molecules can be used as tools by astronomers to probe the temperatures, densities and levels of radiation and ionization in star-forming regions. Interstellar space also represents the ultimate physical chemistry laboratory, providing the ideal testing grounds for fundamental theories of chemistry at temperatures approaching absolute zero.
I will introduce the experiments that we are building in the new UBC Astrochemistry Lab to simulate interstellar environments and support astronomical observations. I will present the major challenges in the field and how we use cutting-edge experiments to approach these questions. These experiments are critical in order to maximize the scientific return from large-scale telescopes like the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Webb Space Telescope (JWST).

Star-forming protoclusters
Event Information:
The Λ cold dark matter (ΛCDM) model accurately reproduces many notable observations of our Universe, such as the existence of galaxy clusters embedded in a cosmic web. However, there remain many open questions about the physics governing baryons on galaxy cluster scales that the ΛCDM model cannot address, such as how star-formation is triggered and quenched, and how feedback processes regulate structure growth. In order to investigate these questions we study SPT2349-56, a star-forming protocluster discovered at redshift 4.3, corresponding to a period when large-scale structure was actively forming.
We use submillimetre observations to search for protocluster members, identifying 29 galaxies at z=4.3. These galaxies are distributed into a central core of 300 kpc in diameter and a northern extension, offset from the core by 400 kpc. We find three additional galaxies 1.5 Mpc from the main structure, suggesting the existence of other halos at the same redshift that are not covered by our data. An analysis of the velocity distribution of the central galaxies indicates that this region may be virialized with a mass of 10^13 M☉, while the two separated galaxy groups show significant velocity offsets from the central group. We estimate the average star-formation rate density of SPT2349-56 to be roughly 40,000 M☉/yr/Mpc^3; this may be an order of magnitude greater than the most extreme examples seen in simulations. We carry out a suite of optical and near-infrared observations in order to characterize the stellar content of SPT2349-56. Using the submillimetre positions of the protocluster members, we identify counterparts and perform detailed source deblending, allowing us to fit spectral energy distributions and estimate stellar masses. We show that the galaxies in SPT2349-56 have stellar masses proportional to their star-formation rates, consistent with other protocluster galaxies and field submillimetre galaxies (SMGs) around redshift 4. However, the galaxies in SPT2349-56 have on average lower molecular gas-to-stellar mass fractions and depletion timescales than field SMGs, although with considerable scatter. Hydrodynamical simulations predict that the core galaxies will quickly merge into a brightest cluster galaxy, thus our observations provide a direct view of the early formation mechanisms of this class of object.

A Subjective History of Physics: from Laplace to Dirichlet
Event Information:
In the Natural Sciences, physical models are often posited and the validity of the model is assessed by comparing model predictions to experimental realizations. Such forward modeling has had its role to play and is heavily showcased throughout Physics, where disparate observations were unified into predictive frameworks inspired by logic, symmetries and other fundamental considerations. Undoubtedly, the forward approach has been tremendously successful. To wit, among many examples, this forward approach predicted the magnetic moment of the electron to a spectacular number of significant digits. But there are limitations to this historically successful approach. While forward modeling historically came first, inverse methods – spurred in equal parts by advances in probability theory (dating back to Laplace) and data-centric questions – have become indispensable as we begin to unravel the complex rules of life from single photon arrivals in Biophysics. Despite their labeling as "inverse", there is nothing backward about inferring models directly from the data. In this talk, we discuss a brief history of inverse methods in Physics and place our recent attempts at unraveling subcellular life from this perspective in our journey from Laplace's principle of indifference to Dirichlet processes.

Christoph Renner: Electronic Vortex Core Structure of a d-Wave High Temperature Superconductor
Event Information:
Abstract:
High temperature superconductivity (HTS) in copper oxides keeps challenging our understanding. Among the outstanding puzzles is the electronic structure of the Abrikosov vortex cores. The fundamental excitations bound to magnetic vortices in type-II superconductors carry information about essential properties of the superconducting state. Their proper identification is therefore of prime interest to elucidate the mechanism driving HTS. We will review recent vortex core studies and present new scanning tunneling microscopy data [1] at low magnetic field, which unveil the d wave electronic structure of the vortex core predicted by Wang and MacDonald in 1995 [2]. We show that previously reported unconventional electronic structures, including the checkerboard charge order in the vortex halo and the absence of a zero-bias conductance peak at the vortex center, are direct consequences of short inter-vortex distance and consequent vortex-vortex interactions prevailing in earlier experiments done at significantly higher field. The remarkable change of the spectroscopic footprint of the vortex cores we find between 0.16 Tesla and 3 Tesla is surprising for such a low energy scale and calls for further investigations.

Planet Formation through the Lens of the Outer Solar System
Event Information:
We currently know of 2000 small bodies in the outer solar system called Kuiper Belt or Trans-Neptunian Objects (TNOs). This population provides crucial information about the formation of the solar system. In particular, there is a sub-population that is an untouched relic of solar system formation, giving us nearly-direct insights into planet formation. For example, recent work shows that non-linear interactions between gas and dust – the streaming instability – is an excellent match to the known properties of this sub-population. While the field has progressed significantly, there are many unanswered questions about the basic properties of TNOs. For example, only about 20 TNOs have measured densities and only a few have measured shapes. The Ragozzine Research Group is working on improving our understanding of TNOs by performing the first orbital analyses that are able to measure or constrain their shapes and spin states. We study TNO binaries by characterizing the "non-Keplerian" signal due to motion around non-spherical bodies and take advantage of advanced Bayesian statistical inference to quantify these subtle effects. We also involve undergraduates in a traditional lecture course to contribute and become co-authors on upcoming publications. I will present our current results including new upper limits on shapes of TNOs as a function of sub-population and the likely detection of an unseen moon around the famous dwarf planet Eris.

Greenland ice cores tell tales on past sea level contributions
Event Information:
The Greenland Ice Sheet is reacting to climate change, and is losing progressively more mass every year. One of our challenges in the future is to adapt to rising sea level. Looking into the past provides knowledge on how the ice sheets react to changing climate, and this can be used to improve future predictions of sea level rise. The deep ice cores from Greenland contain information on past climate that goes back more than 130,000 years, telling tales about past abrupt climate and sea level changes.
The last interglacial, 130,000 to 115,000 years before present, is a key analogue for future climate. At this time, climate was 5 oC warmer over Greenland, and global sea level was 6-9 m higher than present. All the ice cores from Greenland show that the ice sheet survived, making only a modest contribution to global sea level rise of approximately 2 m at this time.
In addition, investigations of basal material from the Greenland ice cores show that there might have been an ice cover over Greenland for 1 million years. This shows a rather resilient ice sheet surviving several warm interglacials. The perspectives of this is discussed in relation to the future climate warming.

Claire Donnelly: Three-dimensional nanomagnetism: from textures in the bulk to 3D magnetic nanostructures
Event Information:
Abstract:
Three dimensional magnetic systems promise significant opportunities for applications, for example providing higher density devices [1] and new functionalities associated with complex topology and greater degrees of freedom [2,3].
With the recent development of three-dimensional imaging techniques, it is now possible to map internal three-dimensional magnetic structures, and their response to external excitations. In this way we have observed three-dimensional vortex structures, as well as Bloch point singularities [4,5] and, more recently, nanoscale magnetic vortex rings [6,7].
In addition to the static magnetic structure, the dynamic response of the 3D magnetic configuration to excitations is key to our understanding of both fundamental physics, and applications. With our recent development of X-ray magnetic laminography [5], it is now possible to determine the magnetisation dynamics of a three-dimensional magnetic system [5].
As well as observing magnetic textures within the “bulk”, recent advances in nanofabrication make possible the fabrication of complex 3D magnetic nanostructures [8]. In this way we have realised magnetic double helices [9], which host highly coupled domain wall pairs that in turn lead to textures in the magnetic induction [9]. These offer not only a potential route to domain wall processing, but also for the patterning of nanotextures in the magnetic field.
These new experimental capabilities for 3D magnetic systems open the door to complex three-dimensional magnetic structures, and their dynamic behaviour.

Laneways: The Most Boring Talk You'll Ever Hear About Vancouver
Event Information:
When lockdown started, I decided to go out for a walk every day. Exploring my immediate neighbourhood turned into a systematic traversal of each street, and then each laneway. Every day I would walk a chunk of Vancouver, and after 20 months I completed every public path that I could find in the entire city. This introduced me to many unfamiliar parts of Vancouver, with the laneways (the neglected network of back alleys) probably holding the most fascination. In this presentation I'll describe some of the the things I discovered along the way and maybe you'll see some unexpected sides of our city. Note: there's no physics in this talk!

10 Years of Stellar Activity from Space
Event Information:
Since the launch of Kepler in 2009, the field of stellar astronomy has been radically changed with the advent of long-duration, high-precision light curves. With the TESS mission we now have space-based light curves for millions of nearby stars, which allow e.g. precise characterization of stellar rotation periods and enormous catalogs of flares. I'll review some of the transformative discoveries that this data has enabled, and highlight unique opportunities for stellar astronomy in the coming decade.

"Picture a Scientist" panel discussion
Event Information:
The PHAS GSA (Grad Student Association) is partnering up with the Society of Graduate Students and Postdocs at TRIUMF (GAPS) and the PHAS E&I group to host a screening of the amazing film Picture A Scientist. It has really taken the science world by storm after its release at the Tribecca Film Festival and is a must see for scientists. GAPS, GSA and E&I are hosting the screening on Wednesday, Dec 1st, 5.30pm @ HENN201 with FREE PIZZA afterward and would love to invite everyone in the department to come and join. For those of us who can't make it to the screening, the film is now on Netflix.
Following the screening, in this PHAS Department Colloquium (Thursday, Dec 2nd, 4pm @ HENN 201) slot there will be a panel discussion on Picture A Scientist. Currently, our panel consists of Jess McIver (UBC - gravitational waves), Allison Man (UBC - galaxy evolution), Aria Malhotra (UBC - radiation therapy), Janis McKenna (UBC - beyond standard model hadronic effects), and Beatrice Franke (TRIUMF,UBC - Ultra-cold neutron studies)! The colloquium will be held in person and on Zoom.
