Black hole solutions in massive gravity [PDF]

, 2009
The static vacuum spherically symmetric solutions in massive gravity are obtained both analytically and numerically. The solutions depend on two parameters (integration constants): the mass M (or, equivalently, the Schwarzschild radius), and an ...

Looking for Intermediate-Mass Black Holes [PDF]

Nuclear Physics B - Proceedings Supplements, 2010
A discussion of the entropy of the universe leads to the suggestion of very many intermediate-mass black holes between thirty and three hundred thousand solar masses in the halo. It is consistent with observations on wide binaries as well as microlensing and considerations of disk stability that such IMBHs constitute all cold dark ...

Tidal Stripping of a White Dwarf by an Intermediate-mass Black Hole

The Astrophysical Journal, 2023
During the inspiralling of a white dwarf (WD) into an intermediate-mass black hole (∼10 ^2−5 M _⊙ ), both gravitational waves (GWs) and electromagnetic (EM) radiation are emitted.

Probing intermediate-mass black hole binaries

Scilight, 2023
Atom interferometers can observe the intermediate band of gravitational waves needed for the long-sought-after detection of merging intermediate-mass black hole binaries.

Primordial intermediate mass black holes as dark matter [PDF]

International Journal of Modern Physics A, 2020
Among particle theory candidates for the dark matter constituents. Axions and WIMPs are the most popular. In this paper, we discuss these then focus on our preferred astrophysical candidate, the Primordial Intermediate Mass Black Holes in the acronym DM[Formula: see text]=[Formula: see text]PIMBHs.

Massive Black Holes in Star Clusters. I. Equal-mass clusters [PDF]

, 2004
In this paper we report results of collisional N-body simulations of the dynamical evolution of equal-mass star clusters containing a massive central black hole.

Ratios of star cluster core and half-mass radii: a cautionary note on intermediate-mass black holes in star clusters

, 2007
There is currently much interest in the possible presence of intermediate-mass black holes in the cores of globular clusters. Based on theoretical arguments and simulation results it has previously been suggested that a large core radius -- or ...

Challenges and Obstacles for a Bouncing Universe in Brane Models [PDF]

, 2003
A Brane evolving in the background of a charged AdS black-hole displays in general a bouncing behaviour with a smooth transition from a contracting to an expanding phase.
