Inferring the spins of merging black holes in the presence of data-quality issues
Rhiannon Udall, Sophie Bini, Katerina Chatziioannou +5
Gravitational waves from black hole binary mergers carry information about the component spins, but inference is sensitive to analysis assumptions, which may be broken by terrestri…
Glitches far from transient gravitational-wave events do not bias inference
Sophie Hourihane, Katerina Chatziioannou
Non-Gaussian noise in gravitational-wave detectors, known as "glitches," can bias the inferred parameters of transient signals when they occur nearby in time and frequency. These b…
Measuring spin precession from massive black hole binaries with gravitational waves: insights from time-domain signal morphology
Simona J. Miller, Maximiliano Isi, Katerina Chatziioannou +2
Robustly measuring binary black hole spins via gravitational waves is key to understanding these systems' astrophysical origins, but remains challenging -- especially for high-mass…
