# Theory of Dark Matter

## TL;DR

This paper explores the hypothesis that primordial intermediate-mass black holes constitute dark matter, discussing detection methods like microlensing and considering factors affecting their observability.

## Contribution

It introduces the idea that PIMBHs could be the main dark matter component and analyzes detection challenges related to their angular momentum.

## Key findings

- PIMBHs are viable dark matter candidates.
- Microlensing is a key detection method.
- Angular momentum affects detectability.

## Abstract

We discuss the hypothesis that the constituents of dark matter in the galactic halo are Primordial Intermediate-Mass Black Holes (PIMBHs). The status of axions and WIMPs is discussed, as are the methods for detecting PIMBHs with emphasis on microlensing. The role of the angular momentum J of the PIMBHs in their escaping previous detection is considered.
