Testing the Kerr Black Hole Hypothesis: X-ray Reflection Spectroscopy
Iron line method is a powerful technique to unveil properties of strong gravity regime and constrain non-Kerr spacetime but it is degenerate and high-quality data is necessary. More recently, there have been studies to use this technique to test the nature of astrophysical black holes (BHs) and verify the Kerr BH hypothesis. Geometrically thin and optically thick accretion disk emits fluorescence narrow lines by hard X-ray photon of optically thin comptonized corona. The strongest line is the iron Kalpha ...
