TAPIR Seminar

Physics near Rapidly Spinning Black Holes
Samuel Gralla, Asst Professor, Dept of Physics, University of Arizona,

When a black hole spins near the maximum rate, its near-horizon region gains additional emergent symmetries and can be thought of as a spacetime in its own right.  I will discuss the dynamics of particles and fields in this region, the constraints imposed by symmetry, and observational consequences.  In particular I will discuss a "smoking gun" gravitational-wave signal of a black hole with near-maximal spin.
