Looking for Intermediate-Mass Black Holes
Paul H. Frampton
TL;DR
This paper proposes that a large population of intermediate-mass black holes could account for all cold dark matter, based on entropy considerations and observational constraints.
Contribution
It introduces the hypothesis that intermediate-mass black holes in the halo can explain dark matter, supported by entropy and observational analyses.
Findings
IMBHs could constitute all cold dark matter
Supported by observations on wide binaries and microlensing
Consistent with disk stability considerations
Abstract
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 matter
