Constraints on Kerr-Newman black holes from merger-ringdown gravitational-wave observations
Gregorio Carullo, Danny Laghi, Nathan K. Johnson-McDaniel +4
We construct a template to model the post-merger phase of a binary black hole coalescence in the presence of a remnant charge. We include the quasi-normal modes typically do…
Investigating the relation between gravitational wave tests of general relativity
Nathan K. Johnson-McDaniel, Abhirup Ghosh, Sudarshan Ghonge +3
Gravitational wave observations of compact binary coalescences provide precision probes of strong-field gravity. There is thus now a standard set of null tests of general relativit…
Inferring spin tilts at formation from gravitational wave observations of binary black holes: Interfacing precession-averaged and orbit-averaged spin evolution
Nathan K. Johnson-McDaniel, Sumeet Kulkarni, Anuradha Gupta
Two important parameters inferred from the gravitational wave signals of binaries of precessing black holes are the spin tilt angles, i.e., the angles at which the black holes' spi…
