The origin of the 511 keV line signal in the Milky Way remains unresolved despite decades of observations. The measured flux of $\sim 3 \times 10^{-3}\,\mathrm{ph\,cm^{-2}\,s^{-1}}…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
-Ray Lines -- Signatures of Nucleosynthesis, Cosmic Rays, Positron Annihilation, and Fundamental Physics

The nuclear -ray lines in the MeV range of the electromagnetic spectrum hold a vast variety of astrophysical, particle-physical, and fundamental physical information that is oth…
Search for Axion-Like Particles from Nearby Pre-Supernova Stars
Saurabh Mittal, Thomas Siegert, Francesca Calore +7
Axion-like particles (ALPs) are hypothetical pseudoscalar bosons that arise in many extensions of the Standard Model and are well-motivated dark matter candidates. Nearby massive s…
Multiwavelength identification of millisecond pulsar candidates in the Galactic bulge
J. Berteaud, F. Calore, M. Clavel +4
The existence of a population of millisecond pulsars in the Galactic bulge is supported, along with other evidence, by the Fermi GeV excess, an anomalous γ-ray emission detected al…
Low-frequency radio telescopes sensitivity to light dark matter
Ruben Zatini, Francesca Calore, Pasquale Dario Serpico
Ground-based radio telescopes are routinely used to search for light dark matter (DM) candidates such as axion-like particles or dark photons. These instruments face however inhere…
Stellar-like Galactic center excess challenges particle dark matter
Silvia Manconi, Christopher Eckner, Francesca Calore +1
The Galactic Center (GC) is potentially hosting the largest indirect signal from particle dark matter (DM), which in many well-motivated models would produce gamma rays as their fi…
Cosmic-ray cooling by dark matter in astrophysical jets
Dimitrios Kantzas, Francesca Calore, Marco Chianese
Astrophysical jets from powerful active galactic nuclei (AGN) have recently been proposed as promising probes of dark matter (DM) in the sub-GeV mass range. AGN launch relativistic…
Lecture Notes: WISPs in gamma-ray astrophysics
Francesca Calore, Christopher Eckner
These lecture notes provide an overview of high-energy astrophysical processes involving axions, axion-like particles (ALPs), and other weakly interacting slim particles (WISPs) fo…
A robust neural determination of the source-count distribution of the Fermi-LAT sky at high latitudes
Christopher Eckner, Noemi Anau Montel, Florian List +2
Over the past 16 years, the Fermi Large Area Telescope (LAT) has significantly advanced our view of the GeV gamma-ray sky, yet several key questions remain - such as the compositio…
Can local White Dwarfs constrain Dark Matter interactions?
Pooja Bhattacharjee, Sandra Robles, Stephan A. Meighen-Berger +1
We investigate whether nearby white dwarfs (WDs) can constrain dark matter (DM) interactions with ordinary matter. As experimental sensitivity improves, driven by the Gaia mission,…
