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…
Gravitational Waves from Fully General Relativistic Oscillon Preheating
Xiao-Xiao Kou, James B. Mertens, Chi Tian +1
As long-lived quasi-solitons from the fragmentation of a scalar condensate, oscillons may dominate the preheating era after inflation. During this period, stochastic gravitational…
Oscillon Preheating in Full General Relativity
Xiao-Xiao Kou, Chi Tian, Shuang-Yong Zhou
Oscillons are dense objects that may be copiously produced in the preheating period after inflation, during which what role general relativity might play is largely unknown. We inv…
