New Class of Dark Matter Objects and their Detection

TL;DR

This paper explores a new class of dark matter objects formed by WIMPs, discussing their properties, formation, detection prospects, and implications for phenomena like black holes and gamma-ray bursts.

Contribution

It introduces a novel class of dark matter objects formed from WIMPs, analyzing their properties, formation mechanisms, and potential observational signatures.

Findings

Dark matter objects can form from WIMPs and are bound by self-gravity.

These objects may lead to primordial black holes.

They could explain short gamma-ray bursts without baryon load issues.

Abstract

About one-fourth of the universe is thought to consist of dark matter. Yet there is no clear understanding about the nature of these particles. Commonly discussed dark matter candidates includes the so called WIMPs or weakly interacting massive particles with masses from about 10GeV to 1TeV. These particles can gravitate to form a new class of objects in dark matter halos or around the galactic centre. We study in some detail many properties of these objects; which are dark matter dominated and bound by their self gravity; their formation and possibilities of their detection. Implications of the presence of such objects for star formation are also discussed. These objects could provide the possibility of forming primordial black holes distinct from the usual Hawking black holes and they could also provide a scenario for short duration gamma ray bursts, avoiding the baryon load problem.
