Quasinormal Modes, the Area Spectrum, and Black Hole Entropy
Olaf Dreyer
The results of canonical quantum gravity concerning geometric operators and black hole entropy are beset by an ambiguity labelled by the Immirzi parameter. We use a result from cla…

Isolated Horizons in 2+1 Gravity
Abhay Ashtekar, Olaf Dreyer, Jacek Wisniewski
Using ideas employed in higher dimensional gravity, non-expanding, weakly isolated and isolated horizons are introduced and analyzed in 2+1 dimensions. While the basic definitions…

Introduction to Isolated Horizons in Numerical Relativity
Olaf Dreyer, Badri Krishnan, Eric Schnetter +1
We present a coordinate-independent method for extracting mass (M) and angular momentum (J) of a black hole in numerical simulations. This method, based on the isolated horizon fra…
