Dark Matter Tomography

TL;DR

This paper explores how gamma-ray observations from WIMP annihilations can be used to reconstruct the dark matter density profile in the universe.

Contribution

It introduces a method to infer the WIMP density profile from the angular distribution of gamma-ray flux resulting from dark matter annihilations.

Findings

Demonstrates the potential to reconstruct dark matter profiles from gamma-ray data.

Analyzes the angular distribution of gamma rays from WIMP annihilations.

Provides a framework for dark matter tomography using gamma-ray observations.

Abstract

We consider Wimp annihilations into monochromatic and continuous $\gamma$'s and the angular distribution of the resulting gammas. We discuss how the WIMP density profile can be reconstructed from the angular dependence of the photon flux.
