Constraining dark matter using 20-year INTEGRAL/IBIS observations II: Sub-GeV dark matter
Jordan Koechler, Pedro De la Torre Luque
We present new constraints on sub-GeV dark matter (DM) annihilation and decay using twenty years of diffuse hard X-ray observations from the INTEGRAL/IBIS telescope. By performing…
Strong Constraints on Line Signals from Dark Matter Annihilation in a Nearby Subhalo
Asier Salces Pérez, Thong T. Q. Nguyen, Pedro De la Torre Luque +1
We present a dedicated search for monochromatic gamma-ray emission from a recently proposed nearby dark matter subhalo candidate. Using nearly 15 years of Fermi-LAT Pass 8 data, we…
Galactic Center Neutrinos from Cosmic Ray-Dark Matter Interactions
Jorge Terol Calvo, Pedro de la Torre Luque, Mainak Mukhopadhyay +2
The IceCube and ANTARES collaborations have recently reported evidence for high-energy neutrinos associated with the Galactic plane and the Galactic Ridge, offering a new pathway t…
Galactic cold clouds constraints on sub-GeV DM and asteroid-mass PBHs
Asier Salces Pérez, Pedro de la Torre Luque
We show that the ionization of molecular and atomic clouds provides a novel probe of dark matter scenarios producing low-energy pairs through annihilation, decay, or Hawki…
INTEGRAL, eROSITA and Voyager Constraints on Light Bosonic Dark Matter: ALPs, Dark Photons, Scalars, and Vectors
Thong T. Q. Nguyen, Pedro De la Torre Luque, Isabelle John +3
The decay of light bosonic dark matter particles can produce a bright electron/positron () flux that can be strongly constrained by local Voyager observations of the direct…
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…
(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…
Multimessenger constraints for electrophilic feebly interacting particles from supernovae
Pedro De la Torre Luque, Shyam Balaji, Pierluca Carenza
Several extensions of the Standard Model predict the existence of sub-GeV particles that can be copiously produced in the cores of supernovae. A broad family of these particles are…
rays from in-flight positron annihilation as a probe of new physics
Pedro De la Torre Luque, Shyam Balaji, Pierluca Carenza +1
The ray emission originating from in-flight annihilation (IA) of positrons is a powerful observable for constraining high-energy positron production from exotic sources. By com…
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-…
Cosmic Ray Antihelium from a Strongly Coupled Dark Sector
Martin Wolfgang Winkler, Pedro De La Torre Luque, Tim Linden
Standard Model extensions with a strongly coupled dark sector can induce high-multiplicity states of soft quarks. Such final states trigger extremely efficient antinucleus formatio…
Optimized FLUKA cross sections for cosmic-ray propagation studies
Pedro De la Torre Luque, Mario Nicola Mazziotta
The current great precision on cosmic-ray (CR) spectral data allows us to precisely test our simple models on propagation of charged particles in the Galaxy. However, our studies a…
