Astro Lunch Seminar: Surabhi Sachdev (UWM/GT)

Making gravitational-wave transient catalogs

We are in the era of gravitational-wave and multi-messenger astronomy, kick-started by the Advanced LIGO and Advanced Virgo detectors. The Advanced detectors concluded their third observing run (O3) in March 2020. The latest catalog of compact binary coalescences from LIGO-Virgo-KAGRA contains 90 events with probability of astrophysical origin greater than 0.5. All events are believed to be mergers of neutron stars or/ and black holes. In this talk, I will describe the data analysis techniques and framework used to produce these catalogs. I will also provide a summary of the observations highlighting what we can learn from these observations.
