Snowmass2021 Cosmic Frontier White Paper: Puzzling Excesses in Dark Matter Searches and How to Resolve Them
Rebecca K. Leane, Seodong Shin, Liang Yang +36
Intriguing signals with excesses over expected backgrounds have been observed in many astrophysical and terrestrial settings, which could potentially have a dark matter origin. Ast…
Diffuse Galactic emission spectrum between 0.5 and 8.0 MeV
Thomas Siegert, Joanna Berteaud, Francesca Calore +2
The last measurement of the diffuse emission spectrum of the Milky Way in the megaelectronvolt (MeV) photon energy range was performed by CGRO/COMPTEL more than 20 years ago. We re…
Measuring the smearing of the Galactic 511 keV signal: positron propagation or supernova kicks?
Thomas Siegert, Roland M. Crocker, Oscar Macias +4
We use 15 years of -ray data from INTEGRAL/SPI in a refined investigation of the morphology of the Galactic bulge positron annihilation signal. Our spatial analysis confirms tha…
Supernova bounds on axion-like particles coupled with nucleons and electrons
Francesca Calore, Pierluca Carenza, Maurizio Giannotti +3
We investigate the potential of type II supernovae (SNe) to constrain axion-like particles (ALPs) coupled simultaneously to nucleons and electrons. ALPs coupled to nucleons can be…
Gamma-ray image reconstruction of the Andromeda galaxy
Celine Armand, Francesca Calore
We analyze about 12 years of Fermi-LAT data in the direction of the Andromeda galaxy (M31). We robustly characterize its spectral and morphological properties against systematic un…
Dissecting the inner Galaxy with -ray pixel count statistics
Francesca Calore, Fiorenza Donato, Silvia Manconi
We combine adaptive template fitting and pixel count statistics in order to assess the nature of the Galactic center excess in Fermi-LAT data. We reconstruct the flux distribution…
