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...

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.
