PSL 93 - Ten Years of Gravitational Wave Astronomy

About the Speaker:

Dr. K.G.Arun is a leading Indian physicist specializing in gravitational-wave theory, data analysis, and multi-messenger astronomy, currently serving as a Professor of Physics at the Chennai Mathematical Institute (CMI). His research focuses on testing general relativity using gravitational waves, waveform modeling for compact binaries, and multi-messenger signals from astrophysical events such as binary neutron star mergers. With a strong foundation in post-Newtonian modelling, instrumental contributions to LIGO/Virgo science, and active involvement in testing gravity and SGRB–GW associations, he is a key scientist in modern astrophysics.

About the Lecture:

Nearly a decade has passed since the LIGO and Virgo detectors made the first direct detection of gravitational waves, marking the dawn of a new era in astronomy. In this talk, he will briefly introduce the fundamentals of gravitational waves and their detection, highlight key scientific insights gained from these observations, and offer a glimpse into what the next decade holds for gravitational-wave astronomy.
