Gravitational Waves from Black-Hole Encounters: Prospects for Ground- and Galaxy-Based Observatories
Subhajit Dandapat, Michael Ebersold, Abhimanyu Susobhanan +6
Close hyperbolic encounters of black holes (BHs) generate certain Burst With Memory (BWM) events in the frequency windows of the operational, planned, and proposed gravitational wa…
Observational limits on the rate of radiation-driven binary black hole capture events
Michael Ebersold, Shubhanshu Tiwari, Leigh Smith +6
Dense astrophysical environments like globular clusters and galactic nuclei can host hyperbolic encounters of black holes which can lead to gravitational-wave driven capture. There…
Tests of General Relativity with GW230529: a neutron star merging with a lower mass-gap compact object
Elise M. Sänger, Soumen Roy, Michalis Agathos +16
On May 29, 2023, the LIGO Livingston observatory detected the gravitational-wave signal GW230529_181500 from the merger of a neutron star with a lower mass-gap compact object. Its…
Scattering of particles by radiation fields: a comparative analysis
Donato Bini, Andrea Geralico, Maria Haney +1
The features of the scattering of massive neutral particles propagating in the field of a gravitational plane wave are compared with those characterizing their interaction with an…
New gravitational waveform model for precessing binary neutron stars with double-spin effects
Marta Colleoni, Felip A. Ramis Vidal, Nathan K. Johnson-McDaniel +3
We present two new frequency-domain gravitational waveform models for the analysis of signals emitted by binary neutron star coalescences: IMRPhenomXAS_NRTidalv2 and IMRPhenomXP_NR…
Time-domain phenomenological multipolar waveforms for aligned-spin binary black holes in elliptical orbits
Maria de Lluc Planas, Antoni Ramos-Buades, Cecilio GarcÃa-Quirós +3
We introduce IMRPhenomTEHM, a new phenomenological time-domain model for eccentric aligned-spin binary black holes. Building upon the accurate quasi-circular IMRPhenomTHM model, IM…
