Next-generation gravitational-wave astronomy: challenges and opportunities

**All are welcome to this event!**
The observation of compact binary mergers by the LIGO/Virgo/KAGRA collaboration marks the dawn of a new era in astronomy. Next-generation ground-based detector (Cosmic Explorer and the Einstein Telescope) will allow us to peer far deeper, and LISA will expand our gravitational wave "senses" by opening a new window at low frequencies. Observations of the gravitational waves emitted by compact binary systems in these two frequency windows can lead to new astrophysical insights and new tests of strong-field gravity. I will highlight some of the new challenges and opportunities presented by next-generation detectors. If time allows it, I will discuss: (i) the challenges of parameter estimation in the presence of waveform systematics and multiple overlapping sources, (ii) improvements in tests of general relativity, and (iii) the current observational status of black hole spectroscopy.
Emanuele Berti received a Ph.D. from the University of Rome "La Sapienza” in 2002. He held postdoctoral positions at the Aristotle University of Thessaloniki, the Institut d’Astrophysique de Paris, Washington University in Saint Louis, and JPL/Caltech. He joined the faculty at the University of Mississippi in 2009, and he moved to Johns Hopkins as professor in 2018.
Berti is a theoretical physicist who specializes in gravitational physics and gravitational-wave astronomy. His research interests include the structure, stability, dynamics and formation of black holes and neutron stars; gravitational-wave signatures of modified theories of gravity and physics beyond the Standard Model; using gravitational waves to understand black hole binary astrophysics and cosmology; and preparing for the challenge of detecting gravitational waves in space with LISA.
Berti is a Fellow of the American Physical Society (APS) and of the International Society on General Relativity and Gravitation (ISGRG). He served on the Chair line of the APS Division of Gravitational Physics (2016-2019) and he is currently President Elect of the ISGRG. He is also a Divisional Associate Editor in Gravitational Physics for Physical Review Letters, and a member of NASA’s U.S. LISA Study Team.
