Characteristics of the Galactic Center excess measured with 11 years of -LAT data

M Di Mauro - Physical Review D, 2021 - APS
The excess of γ rays in the data measured by the Fermi Large Area Telescope from the
galactic center region is one of the most intriguing mysteries in astroparticle physics. This …

The Fermi–LAT Galactic Center Excess: Evidence of Annihilating Dark Matter?

S Murgia - Annual Review of Nuclear and Particle Science, 2020 - annualreviews.org
The center of the Galaxy is one of the prime targets in the search for a signal of annihilating
(or decaying) dark matter. If such a signal were to be detected, it would shed light on one of …

Multimessenger constraints on the dark matter interpretation of the -LAT Galactic Center excess

M Di Mauro, MW Winkler - Physical Review D, 2021 - APS
An excess of γ rays in the data measured by the Fermi Large Area Telescope in the direction
of the Galactic Center has been reported in several publications. This excess, labeled as the …

Strong constraints on thermal relic dark matter from Fermi-LAT observations of the Galactic Center

KN Abazajian, S Horiuchi, M Kaplinghat, RE Keeley… - Physical Review D, 2020 - APS
The extended excess toward the Galactic Center (GC) in gamma rays inferred from Fermi-
LAT observations has been interpreted as being due to dark matter (DM) annihilation. Here …

Exploring the MeV sky with a combined coded mask and Compton telescope: the Galactic Explorer with a Coded aperture mask Compton telescope (GECCO)

E Orlando, E Bottacini, AA Moiseev… - … of Cosmology and …, 2022 - iopscience.iop.org
The sky at MeV energies is currently poorly explored. Here we present an innovative
mission concept that builds upon the heritage of past and current missions improving the …

Foreground mismodeling and the point source explanation of the Fermi Galactic Center excess

M Buschmann, NL Rodd, BR Safdi, LJ Chang… - Physical Review D, 2020 - APS
The Fermi Large Area Telescope has observed an excess of∼ GeV energy gamma rays
from the center of the Milky Way, which may arise from near-thermal dark matter annihilation …

Neural simulation-based inference approach for characterizing the Galactic Center -ray excess

S Mishra-Sharma, K Cranmer - Physical Review D, 2022 - APS
The nature of the Fermi γ-ray Galactic Center excess (GCE) has remained a persistent
mystery for over a decade. Although the excess is broadly compatible with emission …

Galactic Anomalies and Particle Dark Matter

M Fairbairn - Symmetry, 2022 - mdpi.com
This is a brief review of aspects of galactic astrophysics and astronomy which have a
possible bearing on particle dark matter. It is still quite normal for particle physicists to try to …

Spurious point source signals in the galactic center excess

RK Leane, TR Slatyer - Physical Review Letters, 2020 - APS
We reexamine evidence that the Galactic Center Excess (GCE) originates primarily from
point sources (PSs). We show that in our region of interest, non-Poissonian template fitting …

Assessing the impact of hydrogen absorption on the characteristics of the Galactic center excess

M Pohl, O Macias, P Coleman… - The Astrophysical …, 2022 - iopscience.iop.org
We present a new reconstruction of the distribution of atomic hydrogen in the inner Galaxy
that is based on explicit radiation transport modeling of line and continuum emission and a …
