General relativistic simulations of the quasicircular inspiral and merger of charged black holes: GW150914 and fundamental physics implications
G Bozzola, V Paschalidis - Physical Review Letters, 2021 - APS
We perform general-relativistic simulations of charged black holes targeting GW150914. We
show that the inspiral is most efficient for detecting black hole charge through gravitational …

Observational signatures of near-extremal Kerr-like black holes in a modified gravity theory at the Event Horizon Telescope
We study the shadows cast by near-extremal Kerr-modified gravity (MOG) black holes for
different values of the parameter in modified gravity. In particular, we consider an isotropic …
