Geodesic congruences, impulsive gravitational waves and gravitational memory
Martin O'Loughlin, Hovhannes Demirchian
In this paper we introduce a new approach to the study of the effects that an impulsive wave, containing a mixture of material sources and gravitational waves, has on a geodesic co…
Horizon Shells: Classical Structure at the Horizon of a Black Hole
Matthias Blau, Martin O'Loughlin
We address the question of the uniqueness of the Schwarzschild black hole by considering the following question: How many meaningful solutions of the Einstein equations exist that…
Horizon Shells and BMS-like Soldering Transformations
Matthias Blau, Martin O'Loughlin
We revisit the theory of null shells in general relativity, with a particular emphasis on null shells placed at horizons of black holes. We study in detail the considerable freedom…
Wave equations on the linear mass Vaidya metric
Saeede Nafooshe, Martin O'Loughlin
We discuss the near singularity region of the linear mass Vaidya metric. In particular we investi- gate the structure in the numerical solutions for the scattering of scalar and el…
A linear mass Vaidya metric at the end of black hole evaporation
Martin O'Loughlin
We discuss the near singularity region of the linear mass Vaidya metric for massless particles with non-zero angular momentum. In particular we look at massless geodesics with non-…
Micro Black Hole Production and Evaporation
Saeede Nafooshe, Martin O'Loughlin, Maria Vittoria Garzelli
It has been conjectured that Micro Black Holes (MBH) may be formed in the presence of large extra dimensions. These MBHs have very small mass and they decay almost instantaneously.…
