Detectability of microlensed gravitational waves
Simon M. C. Yeung, Mark H. Y. Cheung, Joseph A. J. Gais +2
Gravitational lensing describes the bending of the trajectories of light and gravitational waves due to the gravitational potential of a massive object. Strong lensing by galaxies…
Destabilizing the Fundamental Mode of Black Holes: The Elephant and the Flea
Mark Ho-Yeuk Cheung, Kyriakos Destounis, Rodrigo Panosso Macedo +2
Recent work applying the notion of pseudospectrum to gravitational physics showed that the quasinormal mode spectrum of black holes is unstable, with the possible exception of the…
Searching for ultralight bosons with supermassive black hole ringdown
Adrian Ka-Wai Chung, Joseph Gais, Mark H. Y. Cheung +1
One class of competitive candidates for dark matter is ultralight bosons. If they exist, these bosons may form long-lived bosonic clouds surrounding rotating black holes via superr…
