Modelling supermassive black hole growth: towards an improved sub-grid prescription
Modelling supermassive black hole growth sub-grid prescription
2012/2/24
Accretion onto supermassive black holes (SMBHs) in galaxy formation simulations is frequently modelled by the Bondi-Hoyle formalism. Here we examine the validity of this approach analytically and nume...
Kinematic signature of an intermediate-mass black hole in the globular cluster NGC 6388
black hole physics – globular cluster: individual (NGC 6388) – stars: kinematics and dynamics
2011/10/12
Intermediate-mass black holes (IMBHs) are of interest in a wide range of astrophysical fields. In particular, the possibility of finding them at the centers of globular clusters has recently drawn att...

We review recent progress in numerical relativity simulations of black-hole (BH) spacetimes. Following a brief summary of the methods employed in the modeling, we summarize the key results in three ma...
ON THE GEODESICS FOR SPHERICALLY SYMMETRIC DILATON BLACK HOLE
SPHERICALLY SYMMETRIC DILATON BLACK HOLE
2009/3/26
In this paper we shall investigate the timelike geodesics for an
extremal, spherically symmetric, massless dilaton black hole, using an exact solution
obtained by Gary Horowitz.
