Implications of GW241011 for rotating exotic compact objects
N. V. Krishnendu, Tamara Evstafyeva, Aditya Vijaykumar +17
A number of theoretical proposals have been made for horizonless compact objects with masses and spins similar to those of black holes. While gravitational wave signatures from the…
Uncertainty-aware waveform modeling for high signal-to-noise ratio gravitational-wave inference
Simone Mezzasoma, Carl-Johan Haster, Caroline B. Owen +2
Semi-analytical waveform models for black hole binaries require calibration against numerical relativity waveforms to accurately represent the late inspiral and merger, where analy…
High-precision source characterization of intermediate mass-ratio black hole coalescences with gravitational waves: The importance of higher-order multipoles
Tousif Islam, Scott E. Field, Carl-Johan Haster +1
Intermediate mass ratio inspiral (IMRI) binaries -- containing stellar-mass black holes coalescing into intermediate-mass black holes () -- are a highly anticipated…
A morphology-independent test of the mixed polarization content of gravitational wave signals from compact binary coalescences
Katerina Chatziioannou, Maximiliano Isi, Carl-Johan Haster +1
Gravitational waves in general relativity contain two polarization degrees of freedom, commonly labeled plus and cross. Besides those two tensor modes, generic theories of gravity…
physiCal: A physical approach to the marginalization of LIGO calibration uncertainties
Salvatore Vitale, Carl-Johan Haster, Ling Sun +4
The data from ground based gravitational-wave detectors such as Advanced LIGO and Virgo must be calibrated to convert the digital output of photodetectors into a relative displacem…
GW190521: A Binary Black Hole Merger with a Total Mass of
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1253
On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio…
