Stellar flares cannot explain the Galactic 511 keV emission
Saurabh Mittal, Thomas Siegert, Francesca Calore +12
The authors assess whether stellar flares can produce enough positrons to explain the Milky Way’s 511 keV annihilation line and conclude that flares fall short by several orders of…
Stellar-like Galactic center excess challenges particle dark matter
Silvia Manconi, Christopher Eckner, Francesca Calore +1
The authors re‑analyse Fermi‑LAT gamma‑ray data from the Galactic Center using adaptive template fitting and photon‑count statistics to separate a possible dark‑matter signal from…
New constraints on the central mass contents of Omega Centauri from combined stellar kinematics and pulsar timing
Andrés Bañares-Hernández, Francesca Calore, Jorge Martin Camalich +1
We perform a combined analysis of stellar kinematics and line-of-sight accelerations of millisecond pulsars to investigate the mass contents of Omega Centauri. We consider multiple…
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…
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
Thomas Siegert, Francesca Calore, Pierre Jean +6
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 ot…
