Colloquium:- The speaker will describe their recent work re-analyzing the Gravitational Wave(GW) data made public by the Laser Interferometer Gravitational-Wave Observatory(LIGO) collaboration. More broadly he will discuss some of the outstanding questions related to binary black hole mergers, what the data might be saying and what he and his team might expect in the near future. He will focus on what can be inferred from the spin measurements.

“Copernicus Webinar and Colloquium Series”: To promote scientific discussions during this pandemic, they are organizing an online seminar series, i.e. Copernicus Webinar Series, seeking the most outstanding speakers to introduce innovative ideas and important progress in the field of gravity and cosmology. This series is named after the famous Polish Astronomer, Nicolaus Copernicus, whose discovery eventually marked the dawn of modern science.
