GW seminar: Challenges in Gravitational Wave Data Analysis


After decades of effort, Gravitational Wave (GW) astronomy became a reality with the detection of a binary black hole (BBH) merger in 2015 by LIGO. This remarkable discovery has been followed by the detection of three additional BBH mergers and a binary neutron star inspiral, the latter confirming the association of some short gamma-ray bursts with double neutron star progenitors. Given that LIGO and Virgo have already made detections, even though they have yet to reach their second generation design sensitivities, and given that two additional comparable sensitivity detectors are in the pipeline, the future of ground-based GW astronomy looks very bright. In parallel to the ground-based effort, progress continues to be made in opening up the GW window at lower frequencies using space-based detectors and Pulsar Timing Arrays. In this talk, we will review a critical component of the technology involved in realizing GW astronomy, namely, data analysis. Several different areas of GW data analysis across different frequency regimes will be covered and open challenges (in the speaker’s opinion) will be highlighted.
