We use 413 weeks of publicly available Fermi Pass 8 gamma-ray data combined with recently developed galaxy group catalogs to search for evidence of dark matter annihilation in extragalactic halos. In our study, we use luminosity-based mass estimates and mass-to-concentration relations to infer the J factors and associated uncertainties for hundreds of galaxy groups within a redshift range z≲0.03. We employ a conservative substructure boost factor model, which only enhances the sensitivity by an…

Constraining dark matter annihilation with HSC low surface brightness galaxies
Searches for dark matter annihilation signals have been carried out in a number of target regions such as the Galactic Center and Milky Way dwarf spheroidal galaxies (dSphs), among a few others. Here
Mapping extragalactic dark matter annihilation with galaxy surveys: A systematic study of stacked group searches
Dark matter in the halos surrounding galaxy groups and clusters can annihilate to high-energy photons. Recent advancements in the construction of galaxy group catalogs provide many thousands of
Ruling out dark matter interpretation of the galactic GeV excess by gamma-ray data of galaxy clusters
TLDR
This article reports that there are two excellent galaxy clusters (A2877 and Fornax) which can provide interesting constraints for annihilating dark matter and improves the Fermi-LAT upper limits of annihilation cross sections.
Search for dark matter annihilation in the Milky Way halo
The Milky Way halo is the brightest source of dark matter annihilation on the sky. Indeed, the potential strength of the Galactic dark matter signal can supersede that expected from dwarf galaxies
Dark matter constraints with stacked gamma rays scales with the number of galaxies
Low-surface-brightness galaxies (LSBGs) are interesting targets for searches of dark matter emission due to their low baryonic content. However, predicting their expected dark matter emissivities is
Searching for dark matter annihilation from individual halos: uncertainties, scatter and signal-to-noise ratios
Individual extragalactic dark matter halos, such as those associated with nearby galaxies and galaxy clusters, are promising targets for searches for gamma-rays from dark matter annihilation. We
What the Milky Way’s dwarfs tell us about the Galactic Center extended gamma-ray excess
Author(s): Keeley, Ryan E; Abazajian, Kevork N; Kwa, Anna; Rodd, Nicholas L; Safdi, Benjamin R | Abstract: The Milky Way's Galactic Center harbors a gamma-ray excess that is a candidate signal of
Fermi-LAT Observations of γ-Ray Emission toward the Outer Halo of M31.
TLDR
Evidence is found for an extended excess that appears to be distinct from the conventional MW foreground, having a total radial extension upward of ~120-200 kpc from the center of M31, and plausible interpretations of the excess emission are discussed.
Modeling evolution of dark matter substructure and annihilation boost
We study evolution of dark matter substructures, especially how they lose mass and change density profile after they fall in gravitational potential of larger host halos. We develop an analytical

Constraining particle dark matter using local galaxy distribution
It has been long discussed that cosmic rays may contain signals of dark matter. In the last couple of years an anomaly of cosmic-ray positrons has drawn a lot of attentions, and recently an excess in

Particle Dark Matter Searches Outside the Local Group.
TLDR
It is shown that the most powerful technique to detect a particle DM signal outside the Local Group is to study the angular cross-correlation of nongravitational signals with low-redshift gravitational probes, and that this technique is more sensitive than other extragalactic γ-ray probes.

If the dark matter consists of supersymmetric particles, γ-ray observatories such as the Large Area Telescope aboard the Fermi satellite may detect annihilation radiation from the haloes of galaxies

Annihilation of dark matter particles in cosmological halos (including the halo of the Milky Way) contributes to the diffuse gamma-ray background (DGRB). As this contribution will appear anisotropic
