Correcting for Evidence Uncertainty in the Templated Background Search for the Stochastic Gravitational-Wave Background
Xiao-Xiao Kou, Argyro Sasli, Muhammed Saleem +1
We report a new source of systematic bias in the Bayesian Templated Background Search (TBS) for the astrophysical stochastic gravitational-wave background. This bias arises from th…

Progress toward the detection of the gravitational-wave background from stellar-mass binary black holes: a mock data challenge
Xiao-Xiao Kou, Muhammed Saleem, Vuk Mandic +2
While the third LIGO--Virgo gravitational-wave transient catalog includes 90 signals, it is believed that binary black holes merge somewhere in the Universe every…

On the Stochastic Gravitational Wave Background from Binary Black Hole Mergers Dynamically Assembled in Dense Star Clusters
Xiao-Xiao Kou, Giacomo Fragione, Vuk Mandic
With about a hundred binary black hole (BBH) mergers detected by LIGO-Virgo-KAGRA, and with several hundreds expected in the current O4 run, GWs are revolutionizing our understandi…
