Observing gravitational-wave sources with space-based detectors


  • Alvin Chua Department of Physics, National University of Singapore


Eight years on from LIGO's first detection of gravitational waves (GWs), astrophysical GW sources are now routinely observed by a growing network of ground-based detectors at both high and low frequencies. In the next decade, space interferometers such as the LISA mission will probe the mid-frequency GW band, where the richest population of sources radiate. My talk today will include a broad update on the present status of ground-based observing, followed by a brief introduction to the distinctive challenges of space-based GW astronomy. I will also discuss how modern computational and statistical techniques are being brought to bear on a variety of open problems in LISA scientific analysis.
