Mechanics of rotating isolated horizons - art. no. 044016

Black hole mechanics was recently extended by replacing the more commonly u sed event horizons in stationary space-times with isolated horizons in more general space-times (which may admit radiation arbitrarily close to black holes). However, so far the detailed analysis has been restricted to nonrot ating black holes (although it incorporated arbitrary distortion. as well a s electromagnetic, Yang-Mills, and dilatonic charges). We now fill this gap by first introducing the notion of isolated horizon angular momentum and t hen extending the first law to the rotating case.
