Effects of Early-Universe Inhomogeneity on Bubble Formation: Primordial Black Holes as an Extreme Case
Yijie Chang, Shihang Tang, Haowen Deng +3
Our early Universe is not perfectly homogeneous and it may contain some inhomogeneous sources, which might distort the local spacetime and modify the bubble nucleation rate. Taking…

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…
