We develop a method to perform an untargeted Bayesian search for anisotropic gravitational-wave backgrounds that can efficiently and accurately reconstruct the background intensity…
Spectral Method for the Gravitational Perturbations of Black Holes: Schwarzschild Background Case
Adrian Ka-Wai Chung, Pratik Wagle, Nicolas Yunes
We develop a novel technique through spectral decompositions to study the gravitational perturbations of a black hole, without needing to decouple the linearized field equations in…
Targeted search for the kinematic dipole of the gravitational-wave background
Adrian Ka-Wai Chung, Alexander C. Jenkins, Joseph D. Romano +1
There is growing interest in using current and future gravitational-wave interferometers to search for anisotropies in the gravitational-wave background. One guaranteed anisotropic…
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…
Lensing of Gravitational Waves as a Novel Probe of Graviton Mass
Ka-Wai Chung, Tjonnie Guang Feng Li
The diffraction patterns of lensed gravitational waves encode information about their propagation speeds. If gravitons have mass, the dispersion relation and speed of gravitational…
Upper limits on the temperature of inspiraling astrophysical black holes
Adrian Ka-Wai Chung, Mairi Sakellariadou
We present a method to constrain the temperature of astrophysical black holes through detecting the inspiral phase of binary black hole coalescences. At sufficient separation, insp…
Ringdown Spectroscopy of Rotating Black Holes Pierced by Cosmic Strings
Mark Ho-Yeuk Cheung, Levi Wing-Hei Poon, Ka-Wai Chung +1
Multiple gauge theories predict the presence of cosmic strings with different mass densities . We derive an equation governing the perturbations of a rotating black hole pi…

The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1097
The detection of gravitational waves with Advanced LIGO and Advanced Virgo has enabled novel tests of general relativity, including direct study of the polarization of gravitationa…
Constraints on cosmic strings using data from the first Advanced LIGO observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1042
Cosmic strings are topological defects which can be formed in GUT-scale phase transitions in the early universe. They are also predicted to form in the context of string theory. Th…
