"Gravitational-waves: from black holes to the cosmos"


Maximiliano Isi , Flatiron Institute
[Host: Sayantani Datta]
ABSTRACT:

With the LIGO-Virgo detectors currently undergoing their 4th observing round, gravitational-wave astronomy has matured into a fast-developing field with broad implications for astrophysics, nuclear physics, gravity and cosmology. In this talk, I will focus on recent developments in probing the physics of black holes and their mergers with gravitational waves. This includes measurements of black hole spins and merger kicks, their use as cosmological probes, and the spectroscopic study of ringing black holes. I will outline some of the theoretical and observational questions driving this field: how do black holes form? Can we leverage them as probes of new fundamental fields, dark matter or cosmic expansion? I will conclude by arguing that we are at the cusp of observationally tackling these and many other fascinating questions as we enter the era of precision gravitational-wave science, with current and future observatories in space and on the ground.
