Evaporation of 2-Dimensional Black Holes
Abhay Ashtekar, Frans Pretorius, Fethi M. Ramazanoğlu
We present a detailed analysis of results from a new study of the quantum evaporation of Callan-Giddings-Harvey-Strominger (CGHS) black holes within the mean-field approximation. T…
Superkicks in ultrarelativistic encounters of spinning black holes
Ulrich Sperhake, Emanuele Berti, Vitor Cardoso +2
We study ultrarelativistic encounters of two spinning, equal-mass black holes through simulations in full numerical relativity. Two initial data sequences are studied in detail: on…
Surprises in the Evaporation of 2-Dimensional Black Holes
Abhay Ashtekar, Frans Pretorius, Fethi M. Ramazanoğlu
Quantum evaporation of Callan-Giddings-Harvey-Strominger (CGHS) black holes is analyzed in the mean field approximation. This semi-classical theory incorporates back reaction. Deta…
Two-dimensional quantum black holes: Numerical methods
Fethi M Ramazanoğlu, Frans Pretorius
We present details of a new numerical code designed to study the formation and evaporation of 2-dimensional black holes within the CGHS model. We explain several elements of the sc…
Linear Stability Analysis and the Speed of Gravitational Waves in Dynamical Chern-Simons Modified Gravity
David Garfinkle, Frans Pretorius, Nicolas Yunes
We perform a linear stability analysis of dynamical Chern-Simons modified gravity in the geometric optics approximation and find that it is linearly stable on the backgrounds consi…
Black Strings, Low Viscosity Fluids, and Violation of Cosmic Censorship
Luis Lehner, Frans Pretorius
We describe the behavior of 5-dimensional black strings, subject to the Gregory-Laflamme instability. Beyond the linear level, the evolving strings exhibit a rich dynamics, where a…
