Supermassive black hole growth in hierarchically merging nuclear star clusters
Konstantinos Kritos, Ricarda S. Beckmann, Joseph Silk +5
Supermassive black holes are prevalent at the centers of massive galaxies, and their masses scale with galaxy properties, increasing evidence suggesting that these trends continue…
Systematic biases due to waveform mismodeling in parametrized post-Einsteinian tests of general relativity: The impact of neglecting spin precession and higher modes
Rohit S. Chandramouli, Kaitlyn Prokup, Emanuele Berti +1
We study the robustness of parametrized post-Einsteinian (ppE) tests of General Relativity (GR) with gravitational waves, due to waveform inaccuracy. In particular, we determine th…
Revealing the elusive companion of the red giant binary 2MASSJ05215658+4359220 from UV HST and Astrosat-UVIT data
Luciana Bianchi, John Hutchings, Ralph Bohlin +2
Black hole demographics in different environments is critical in view of recent results on massive-stars binarity, and of the multi-messenger detectability of compact objects merge…
Minimum gas mass accreted by spinning intermediate-mass black holes in stellar clusters
Konstantinos Kritos, Luca Reali, Davide Gerosa +1
The spin of intermediate-mass black holes (IMBHs) growing through repeated black hole mergers in stellar clusters statistically asymptotes to zero. Putative observations of IMBHs w…
Spectral instability of black holes: relating the frequency domain to the time domain
Yiqiu Yang, Zhan-Feng Mai, Run-Qiu Yang +2
Recent work has shown that the quasinormal mode spectrum of black holes is unstable under small perturbations (of order ) of the radial potential, while the early time-domain ri…
Supermassive black holes from runaway mergers and accretion in nuclear star clusters
Konstantinos Kritos, Emanuele Berti, Joseph Silk
Rapid formation of supermassive black holes occurs in dense nuclear star clusters that are initially gas-dominated. Stellar-mass black hole remnants of the most massive cluster sin…
Probing minihalo lenses with diffracted gravitational waves
Mark Ho-Yeuk Cheung, Ken K. Y. Ng, Miguel Zumalacárregui +1
When gravitational waves pass near a gravitating object, they are deflected, or lensed. If the object is massive, such that the wavelength of the waves is small compared to its gra…
Nonlinear quasinormal mode detectability with next-generation gravitational wave detectors
Sophia Yi, Adrien Kuntz, Enrico Barausse +4
In the aftermath of a binary black hole merger event, the gravitational wave signal emitted by the remnant black hole is modeled as a superposition of damped sinusoids known as qua…
Multi-messenger Astrophysics of Black Holes and Neutron Stars as Probed by Ground-based Gravitational Wave Detectors: From Present to Future
Alessandra Corsi, Lisa Barsotti, Emanuele Berti +12
The ground-based gravitational wave (GW) detectors LIGO and Virgo have enabled the birth of multi-messenger GW astronomy via the detection of GWs from merging stellar-mass black ho…
Gravitational Magnus effect from scalar dark matter
Zipeng Wang, Thomas Helfer, Dina Traykova +2
In fluid dynamics, the Magnus effect is the force perpendicular to the motion of a spinning object as it moves through a medium. In general relativity, an analogous effect exists f…
Beyond the far side: Observing black hole mergers beyond the pair-instability mass gap with next-generation gravitational wave detectors
Gabriele Franciolini, Konstantinos Kritos, Luca Reali +2
Stellar evolution predicts the existence of a mass gap for black hole remnants produced by pair-instability supernova dynamics, whose lower and upper edges are very uncertain. We s…
