Title |
Testing The Kerr Spacetime With X-ray Reflection Spectroscopy | |||||

Abstract |
Astrophysical black holes are thought to be Kerr solution of general relativity but their Kerr geometry have not yet verified. Iron line is prominent feature in X-ray reflection spectra. Shape of iron line in X-ray reflection spectra of both stellar-mass and super massive black hole candidates are supposed to be strongly affected by spacetime geometry. This method is a powerful technique to prob strong gravity regime and deviations from Kerr spacetime. In this talk, I present iron line of some non-Kerr spacetimes. I also present data simulations of X-ray missions. The purpose is to understand whether X-ray reflection spectroscopy can distinguish these non-Kerr spacetimes from Kerr solution of general relativity. |
