"Towards Measuring Black Hole Spin"
Jon Miller
University of Michigan
Constraints on black hole spin are just within reach of present techniques and instrumentation. Spin can determine how much radiation black holes can pump into their galactic environments, the nature of relativistic jets that black holes launch, and - perhaps most interestingly - the nature of the spacetime close to black hole itself. At present, no technique for constraining spin is mature, but the potential for tight constraints that can properly be called "measurements" is real. I will review current progress towards constraining the spin parameter of both stellar-endpoint black holes, and the supermassive black holes in the center of galaxies.
