Gravitational collapse of a radiating shell and radiation bursts
Roberto Casadio
We study the collapse of a self-gravitating thick shell of bosons coupled to a scalar radiation field. Due to the non-adiabaticity of the collapse, the shell (quantum) internal deg…

Testing string theory via black hole space-times
R. Casadio, B. Harms
Charged black holes, both spherically symmetric and rotating, in the low energy limit of string theory (Einstein-Maxwell-dilaton theory) are compared to analogous geometries in pur…

Semiclassical Quantization on Black Hole Spacetimes
R. Casadio, B. Harms, Y. Leblanc
The thermodynamical description of black holes is reviewed and critiqued. We present an alternative, microcanonical description of black holes and discuss the major differences. In…
