Spin dependence of black hole ringdown nonlinearities
Jaime Redondo-Yuste, Gregorio Carullo, Justin L. Ripley +2
The nonlinear character of general relativity leaves its imprint in the coalescence of two black holes, from the inspiral to the final ringdown stage. To quantify the impact of non…
Report of the Topical Group on Cosmic Probes of Fundamental Physics for for Snowmass 2021
Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang +118
Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probe…
Nonlinear effects in black hole ringdown
Mark Ho-Yeuk Cheung, Vishal Baibhav, Emanuele Berti +8
We report evidence for nonlinear modes in the ringdown stage of the gravitational waveform produced by the merger of two comparable-mass black holes. We consider both the coalescen…
Electromagnetic emission from axionic boson star collisions
Nicolas Sanchis-Gual, Miguel Zilhão, Vitor Cardoso
We explore the dynamics of boson stars in the presence of axionic couplings through nonlinear evolutions of Einstein's field equations. We show that, for large axionic couplings, i…
Observational signatures of hot spots orbiting horizonless objects
João Luís Rosa, Paulo Garcia, Frédéric H. Vincent +1
Pushed by a number of advances, electromagnetic observatories have now reached the horizon scale of supermassive black holes. The existence and properties of horizons in our univer…
Analysis of Ringdown Overtones in GW150914
Roberto Cotesta, Gregorio Carullo, Emanuele Berti +1
We analyze GW150914 post-merger data to understand if ringdown overtone detection claims are robust. We find no evidence in favor of an overtone in the data after the waveform peak…
