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 …
Importance of cosmic ray propagation on sub-GeV dark matter constraints
Pedro De la Torre Luque, Shyam Balaji, Jordan Koechler
We study sub-GeV dark matter (DM) particles that may annihilate or decay into SM particles producing an exotic injection component in the Milky Way that leaves an imprint in both p…
Gamma-Ray Lines in 15 Years of Fermi-LAT Data: New Constraints on Higgs Portal Dark Matter
Pedro De La Torre Luque, Juri Smirnov, Tim Linden
Monoenergetic -ray spectral lines are among the cleanest signatures of dark matter annihilation. We analyze 15 years of Fermi-LAT data, find no spectral lines, and place strong…
Multimessenger search for electrophilic feebly interacting particles from supernovae
Pedro De la Torre Luque, Shyam Balaji, Pierluca Carenza
We study MeV-scale electrophilic Feebly Interacting Particles (FIPs), that may be abundantly produced in Supernova (SN) explosions, escape the star and decay into electrons and pos…
Robust constraints on feebly interacting particles using XMM-Newton
Pedro De la Torre Luque, Shyam Balaji, Pierluca Carenza
During galactic Supernova (SN) explosions, a large amount of feebly interacting particles (FIPs) may be produced. In this work we analyze electrophilic FIPs with masses in the MeV-…
Possible contribution of X-ray binary jets to the Galactic cosmic ray and neutrino flux
Dimitrios Kantzas, Sera Markoff, Alex J. Cooper +3
For over a century, the identification of high-energy cosmic ray (CR) sources remains an open question. For Galactic CRs with energy up to eV, supernova remnants (SNRs) h…
