Partial Tidal Disruptions of Main-sequence Stars by Intermediate-mass Black Holes
We study close encounters of a 1 M _⊙ middle-age main-sequence star (modeled using MESA) with massive black holes through hydrodynamic simulations, and explore in particular the dependence of the outcomes on the black hole mass.

Entropy of the Universe and Hierarchical Dark Matter
We discuss the relationship between dark matter and the entropy of the universe, with the premise that dark matter exists in the form of primordial black holes (PBHs) in a hierarchy of mass tiers. The lightest tier includes all PBHs with masses below one

Intermediate-Mass Black Hole Candidate ULXs [PDF]
In a subset of the most luminous of the so-called “ultra-luminous” X-ray sources in nearby galaxies, there is evidence for black holes with masses considerably higher than found in Galactic binaries. Apart from extremely high X-ray luminosities, cool disks found in the X-ray spectra of these sources and X-ray timing measurements form the basis for ...

Intermediate Mass Black Holes: Their Motion and Associated Energetics
There is a lot of current astrophysical evidence and interest in intermediate mass black holes (IMBH), ranging from a few hundred to several thousand solar masses.

Intermediate-mass black holes in binary-rich star clusters [PDF]
AbstractThree-body interactions of stellar-mass binaries with intermediate mass black holes (IMBHs) in nuclei of globular clusters may produce specific features that may serve as an independent indicator of existence of the IMBHs. By means of direct N-body integrations we follow the dynamical evolution of globular clusters of moderate extension and ...

Looking for Intermediate-Mass Black Holes [PDF]
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 ...

Primordial intermediate mass black holes as dark matter [PDF]
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.
