Bring the Heat: Tidal Heating Constraints for Black Holes and Exotic Compact Objects from the LIGO-Virgo-KAGRA Data
Horng Sheng Chia, Zihan Zhou, Mikhail M. Ivanov
We present the first constraints on tidal heating for the binary systems detected in the LIGO-Virgo-KAGRA (LVK) gravitational wave data. Tidal heating, also known as tidal dissipat…
In Pursuit of Love: First Templated Search for Compact Objects with Large Tidal Deformabilities in the LIGO-Virgo Data
Horng Sheng Chia, Thomas D. P. Edwards, Digvijay Wadekar +6
We report results on the first matched-filtering search for binaries with compact objects having large tidal deformabilities in the LIGO-Virgo gravitational wave (GW) data. The tid…
Self-Interacting Gravitational Atoms in the Strong-Gravity Regime
Horng Sheng Chia, Christoffel Doorman, Alexandra Wernersson +2
We numerically investigate free and self-interacting ultralight scalar fields around black holes in General Relativity. We focus on complex scalar fields whose self-interaction…
Dimensionally Reduced Waveforms for Spin-Induced Quadrupole Searches
Horng Sheng Chia, Thomas D. P. Edwards, Richard N. George +5
We present highly accurate, dimensionally-reduced gravitational waveforms for binary inspirals whose components have large spin-induced quadrupole moments. The spin-induced quadrup…
Tidal Deformation and Dissipation of Rotating Black Holes
Horng Sheng Chia
We show that rotating black holes do not experience any tidal deformation when they are perturbed by a weak and adiabatic gravitational field. The tidal deformability of an object…
Gravitational Collider Physics
Daniel Baumann, Horng Sheng Chia, Rafael A. Porto +1
We study the imprints of new ultralight particles on the gravitational-wave signals emitted by binary black holes. Superradiant instabilities may create large clouds of scalar or v…
The Spectra of Gravitational Atoms
Daniel Baumann, Horng Sheng Chia, John Stout +1
We compute the quasi-bound state spectra of ultralight scalar and vector fields around rotating black holes. These spectra are determined by the gravitational fine structure consta…
Probing Ultralight Bosons with Binary Black Holes
Daniel Baumann, Horng Sheng Chia, Rafael A. Porto
We study the gravitational-wave (GW) signatures of clouds of ultralight bosons around black holes (BHs) in binary inspirals. These clouds, which are formed via superradiance instab…
