# Point Sources from Dissipative Dark Matter

## TL;DR

Dissipative dark matter could form dense compact objects that produce point-like signals, potentially explaining gamma-ray excesses from the galactic center through novel indirect detection signatures.

## Contribution

This paper introduces models of dissipative dark matter that form compact objects, providing a new mechanism for gamma-ray signals and linking dark matter properties to observable astrophysical phenomena.

## Key findings

- Dissipative dark matter can form dense astrophysical objects.
- Such objects can produce point-like gamma-ray signals.
- Models can explain the galactic center gamma-ray excess.

## Abstract

If a component of dark matter has dissipative interactions, it can cool to form compact astrophysical objects with higher density than that of conventional cold dark matter (sub)haloes. Dark matter annihilations might then appear as point sources, leading to novel morphology for indirect detection. We explore dissipative models where interaction with the Standard Model might provide visible signals, and show how such objects might give rise to the observed excess in gamma rays arising from the galactic center.
