Testing the Kerr black hole hypothesis using X-ray reflection spectroscopy
Cosimo Bambi, Alejandro Cardenas-Avendano, Thomas Dauser +2
We present the first X-ray reflection model for testing the assumption that the metric of astrophysical black holes is described by the Kerr solution. We employ the formalism of th…
