Probing the black hole charge from binary inspirals
Probing the black hole charge from binary inspirals
Along with the mass and the angular momentum, which typical astrophysical black holes (BHs) are endowed with, theories beyond GR generically induce `charge' to these BHs. This study explores the compact binary observations and constrain the properties of braneworld black holes using the charge measurement. Full details: Phys. Rev. D 109, 124047, Published 20 June 2024

Testing the Binary Black Hole Nature of a Compact Binary Coalescence
Testing the Binary Black Hole Nature of a Compact Binary Coalescence
A novel method to test the nature of compact objects using gravitational wave measurements of spin-induced quadrupole moments. Best constraints from fastly spinning compact objects. Can we distinguish binary black hole observations from black hole mimickers such as boson stars?
