Black-hole superradiance may make it possible to detect or constrain yet-undiscovered ultralight bosons using gravitational waves. In this talk, I will describe how we may achieve this with ground-based detectors by searching for continuous gravitational waves from known black holes. This includes black holes in x-ray binaries and remnants from compact-binary mergers. I will present results from the recovery of simulated signals from noisy data using hidden Markov models. This efficient data analysis technique will make it possible to target remnants from compact-binary mergers localized with at least three instruments like LIGO and Virgo. I will present sensitivity projections for 2G and 3G ground-based detectors and, in closing, discuss specific potential targets and their associated challenges.
*LIGO was constructed by Caltech and MIT with funding from the NSF and operates under cooperative agreement PHY-0757058. Support for this work was provided by NASA through the NASA Hubble Fellowship grant #HST-HF2-51410.001-A awarded by the Space Telescope Science Institute, operated under contract NAS5-26555. This work was also supported by Australian Research Council (ARC) Discovery Project DP110103347 and the ARC Centre of Excellence for Gravitational Wave Discovery CE17010004.
