Ultralight Bosons Explain the Mass-Spin Correlations in the Merging Binary Black Hole Population
Xiao-Xiao Kou, Vuk Mandic, Ran Ding +1
Ultralight bosons could trigger superradiant instabilities in rapidly spinning black holes, forming oscillating clouds while extracting rotational energy. We consider an extended,…

Estimating the gravitational wave background anisotropy: a Bayesian approach boosted by cross-correlation angular power spectrum
Chi Tian, Ran Ding, Xiao-Xiao Kou
We introduce a new method designed for Bayesian inference of the angular power spectrum of the Gravitational Wave Background (GWB) anisotropy. This scheme works with time-series da…
