DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HETatNTUA/1/
 ">Gravitational Waves as Probes of Strong-Field Gravity</a>\nby Michalis A
 gathos (University of Cambridge & Friedrich-Schiller-Universitat Jena) as 
 part of High Energy Theory\, Gravity  and Cosmology Seminars @ NTUA\n\n\nA
 bstract\nThe first observations of gravitational waves (GWs) from the coal
 escence of a black-hole binary in 2015 and a neutron-star binary in 2017 h
 eralded the beginning of a new era in experimental gravity. In just 5 year
 s\, the detection of GWs has evolved from virtually non-existent to a week
 ly business and has led to a plethora of results with implications for fun
 damental physics\, astrophysics and cosmology. In this talk\, I will give 
 an overview of the GW events detected so far by LIGO and Virgo and will de
 scribe how these can be used to probe the true nature of gravity and test 
 general relativity (GR) to unprecedented levels. I will focus on an array 
 of methods developed exactly for this purpose and will give an update on t
 heir latest results\, with the analysis of signals from compact binaries\,
  detected in the first three observing runs of the Advanced LIGO-Virgo net
 work of detectors. If time allows\, I will briefly discuss the prospects o
 f testing the predictions of GR with future GW detectors\, including upgra
 des and extensions of the current network\, 3rd generation ground-based in
 terferometers and future space-bound detectors.\n
