Lyman-alpha emission is produced ubiquitously by excited hydrogen, so it is a powerful tracer of the interactions among gas, stars, and AGN that shape galaxy formation. However, the resonant scattering of this emission line makes its interpretation complex. In this talk, I will describe three related surveys of galaxies at z~2-3 that make use of Lyman-alpha emission: the Keck Baryonic Structure Survey (KBSS), the KBSS-Lya, and the Keck Lyman Continuum Survey (KCLS).

No experiment today provides evidence that gravity requires a quantum description. It has been suggested that one can at least exclude the possibility for semiclassical gravity by performing an experiment whose outcome cannot be explained by a purely classical source mass configuration.

The connection between physics and finance goes back hundreds of years, and the names of the earliest physicists who studied finance may be surprising. In the 18th century Bernoulli discovered Euler's constant e when investigating compound interest; more re

Abstract: New Jersey Institute of Technology's Expanded Owens Valley Solar Array (EOVSA) has amply demonstrated the power of radio imaging spectroscopy for imaging and quantitative diagnostics of both the flaring and non-flaring Sun. The unique sensitivity of radio emission to the flaring coronal magnetic field has been dramatically shown in a series of recent papers, along with accelerated-electron diagnostics in the same volume. The coming solar maximum (cycle 25) is slated to peak in 2025-2026, which promises to bring new space- and ground-based instruments together with EOVSA to provi

Black holes are interesting spacetime configurations predicted by general relativity. When quantum mechanics is taken into account, black holes are found to emit thermal radiation, called "Hawking radiation".
During the past couple of years a surprising new way to compute its entropy has emerged. This result indicates that the black hole formation and evaporation is consistent with standard quantum mechanical laws.

Many years ago (in 2004), the Rutgers University physics education research group devised a list of most common processes that physicists engage in when creating and applying physics knowledge to operationalize the vague notion of “critical thinking” that we wish our students to develop. This list was based on the observations and interviews of practicing physicists and the studies of the history of physics. The list became the list of "scientific abilities" that students can develop when taking physics courses.

Abstract: For decades, physicists have conducted experimental tests of quantum entanglement, a phenomenon that Albert Einstein once dismissed as "spooky action at a distance." Despite Einstein's misgivings, the experiments have consistently found results compatible with quantum theory; today entanglement is at the heart of next-generation devices like quantum computers and quantum encryption. Yet every experimental test has been subject to one or more "loopholes," which (in principle) could account for the results even in the absence of genuine quantum entanglement.
