SUMMARY:Gravitational-wave astronomy with LIGO-Virgo-KAGRA\, Physics D
 epartment Colloquium\, Patrick Brady\, University of Wisconsin-Milwauk
 ee
DESCRIPTION:Brady will describe the current state of ground-based\, gr
 avitational-wave astronomy and the prospects for the future. He will p
 resent highlights from LIGO-Virgo-KAGRA observations including recent 
 findings on compact object mergers. Gravitational waves from black-hol
 e-binary mergers are now being detected about twice per week and astro
 nomers are eagerly awaiting the next multi-messenger event. Over the n
 ext decade\, a sequence of upgrades will more than double the amplitud
 e sensitivity of the most sensitive gravitational-wave detectors and i
 ncrease the rate of compact binary detections by about a factor of ten
 . Brady will discuss how the improved signal-to-noise ratio will also 
 enable unprecedented measurements of masses\, spins\, and other proper
 ties of black holes and neutron stars in binary systems. The upgrades 
 may also bring the discovery of other gravitational-wave sources. The 
 talk will end with a discussion of future directions for ground-based 
 gravitational-wave astronomy\, highlighting the opportunities for mult
 imessenger astronomy in the early 2030s and how operations of the curr
 ent detector network can dovetail with operations of next-generation f
 acilities such as Cosmic Explorer and Einstein Telescope.
