Constraining Black Hole Horizon Properties Through Long-Duration Gravitational Wave Observations
Ikram Hamoudy, Julian Westerweck, Ofek Birnholtz
We perform a long-duration Bayesian analysis of gravitational-wave data to constrain the near-horizon geometry of black holes formed in binary mergers. Deviations from the Kerr geo…

An upper limit on the frequency of short-period black hole companions to Sun-like stars
Matthew J. Green, Yoav Ziv, Hans-Walter Rix +9
Stellar-mass black holes descend from high-mass stars, most of which had stellar binary companions. However, the number of those binary systems that survive the binary evolution an…
