Measuring black hole spin using X-ray reflection spectroscopy
CS Reynolds - The Physics of Accretion onto Black Holes, 2015 - Springer
I review the current status of X-ray reflection (aka broad iron line) based black hole spin
measurements. This is a powerful technique that allows us to measure robust black hole …
