New 511 keV line data provides strongest sub-GeV dark matter constraints
Pedro De la Torre Luque, Shyam Balaji, Joseph Silk
We explore the ~keV emission associated to sub-GeV dark matter (DM) particles that can produce electron-positron pairs and form positronium after thermalizing. We use …
(H)ALPing the 511 keV line: A thermal DM interpretation of the 511 keV emission
Mohammad Aghaie, Pedro De la Torre Luque, Alessandro Dondarini +3
We propose a novel framework where MeV-scale Dirac Dark Matter annihilates into axion-like particles, providing a natural explanation for the 511 keV gamma-ray line observed in the…
An Excited Dark Matter Solution to the MeV Galactic Center Excesses
Shyam Balaji, Damon Cleaver, Pedro De la Torre Luque
Recent COMPTEL data analysis reveals a 2 MeV continuum excess whose spatial distribution closely matches the long-standing 511 keV line observed by INTEGRAL/SPI, indicating…
Dark Matter in X-rays: Revised XMM-Newton Limits and New Constraints from eROSITA
Shyam Balaji, Damon Cleaver, Pedro De la Torre Luque +1
We investigate two classes of dark matter (DM) candidates, sub-GeV particles and primordial black holes (PBHs), that can inject low-energy electrons and positrons into the Milky Wa…
Search for Diffuse Galactic Neutrinos with the Full ANTARES Telescope Dataset
ANTARES Collaboration, Pedro De la Torre Luque, Daniele Gaggero +4
The diffuse emission of gamma-rays and neutrinos, produced by interactions of cosmic rays with interstellar matter in the Milky Way, provides valuable insights into cosmic ray prop…
