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…
Constraining dark matter using 20-year INTEGRAL/IBIS observations I: Primordial black holes
Jordan Koechler, Pedro De la Torre Luque
Primordial black holes (PBHs) in the asteroid-mass window remain a viable dark matter candidate. In the lower part of this mass range, Hawking evaporation produces electrons and po…
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…
Sgr A* as a Galactic PeVatron: Multimessenger Signatures of the Magnetic Penrose Process
Marina Cermeño, Pedro De la Torre Luque, Cristina Fernández-Suárez +5
The magnetic Penrose process (MPP) is one of the most efficient mechanisms for extracting rotational energy from a magnetized Kerr black hole (BH), enabling charged particles to re…
Decisive evidence for a global cosmic-ray feature in gamma-ray data
Fernando Valenciano, Pedro De la Torre Luque, Daniele Gaggero +1
We analyze 17 years of Fermi-LAT data to study the diffuse -ray emission along the Galactic plane and its connection to cosmic-ray (CR) propagation. Accounting for correlated in…
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…
Exploring the nature of Galactic unassociated sources detected by the Fermi-LAT
F. Acero, A. Acharyya, A. Adelfio +120
We investigate the nature of the unassociated sources detected by the Fermi-LAT close (|b|<10°) to the Galactic plane, representing 16% of all sources in the 4FGL-DR4 catalog. The…
Strong Constraints on Millisecond Pulsar Injection Spectra from Fermi-LAT Observations of the Galactic Center
Jordan Koechler, Pedro De la Torre Luque, Mattia Di Mauro
Millisecond pulsars (MSPs) are a leading explanation of the Galactic Center excess (GCE) observed in Fermi-LAT data. We constrain this scenario by jointly modeling prompt and inver…
The potential of diffuse Galactic Ridge neutrino measurements to constrain dark matter
Jaume Zuriaga-Puig, Pedro de la Torre Luque, Viviana Gammaldi
We use the latest ANTARES Galactic Ridge neutrino measurements to investigate their implications for indirect dark matter (DM) searches. We consider both annihilating and decaying…
Do the sources of the 511 keV excess explain the anomalous CMZ ionization?
Pedro De la Torre Luque, Francesca Calore
The anomalous rate of molecules ionization observed at the Central Molecular zone (CMZ) challenges known mechanisms of ionization observed in molecular clouds across the Galaxy, du…
