Probing the Black Hole Metric. I. Black Hole Shadows and Binary Black-Hole Inspirals
Dimitrios Psaltis, Colm Talbot, Ethan Payne +1
In General Relativity, the spacetimes of black holes have three fundamental properties: (i) they are the same, to lowest order in spin, as the metrics of stellar objects; (ii) they…
Fast, flexible, and accurate evaluation of gravitational-wave Malmquist bias with machine learning
Colm Talbot, Eric Thrane
Many astronomical surveys are limited by the brightness of the sources, and gravitational-wave searches are no exception. The detectability of gravitational waves from merging bina…
Evidence for hierarchical black hole mergers in the second LIGO--Virgo gravitational-wave catalog
Chase Kimball, Colm Talbot, Christopher P. L. Berry +10
We study the population properties of merging binary black holes in the second LIGO--Virgo Gravitational-Wave Transient Catalog assuming they were all formed dynamically in gravita…
Gravitational-wave astronomy with a physical calibration model
Ethan Payne, Colm Talbot, Paul D. Lasky +2
We carry out astrophysical inference for compact binary merger events in LIGO-Virgo's first gravitational-wave transient catalog (GWTC-1) using a physically motivated calibration m…
Measuring the primordial gravitational-wave background in the presence of astrophysical foregrounds
Sylvia Biscoveanu, Colm Talbot, Eric Thrane +1
Primordial gravitational waves are expected to create a stochastic background encoding information about the early Universe that may not be accessible by other means. However, the…
Neutron Star Extreme Matter Observatory: A kilohertz-band gravitational-wave detector in the global network
K. Ackley, V. B. Adya, P. Agrawal +160
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influen…
