Abstract
Ultralight bosons with masses in the range 10-13 eV≤mb≤10-12 eV can induce a superradiant instability around spinning black holes (BHs) with masses of order 10-100 M. This instability leads to the formation of a rotating "bosonic cloud" around the BH, which can emit gravitational waves (GWs) in the frequency band probed by ground-based detectors. The superposition of GWs from all such systems can generate a stochastic gravitational-wave background (SGWB). In this work, we develop a Bayesian data analysis framework to study the SGWB from bosonic clouds using data from Advanced LIGO and Advanced Virgo, building on previous work by Brito et al. [Phys. Rev. D 96, 064050 (2017)PRVDAQ2470-001010.1..
