In this video from PASC18, Salvatore Vitale from the Massachusetts Institute of Technology presents: Methods and Challenges in the Characterization of Gravitational-Wave Sources.
“Advanced gravitational-wave detectors have so far detected signals emitted by the coalescence of two neutron stars or two black holes. Their astrophysical (masses, spins) and extrinsic (position, orientation) parameters have been estimated using stochastic samplers that efficiently explore a 15D parameter space. Although theoretically straightforward, parameter estimation can become non trivial due to the time required to calculate waveform models, the behavior of the noise, and the correlation between parameters. In this talk I will review the main methods results, and challenges associated with the characterization of compact binaries detected by advanced LIGO and Virgo. I will also underline which new challenges will arise as the sensitivity of gravitational-wave detectors improves by a factor of few or a factor of 10.”
