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 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…
Revisiting predictions for cosmic-ray antinucleon fluxes from Galactic Dark Matter
Lorenzo Stefanuto, Mattia Di Mauro, Fiorenza Donato +3
The data on cosmic antiprotons have reached an outstanding precision on energies spanning from GeV to hundreds of TeV, thanks to the space-based AMS-02 experiment. The balloon-born…
Toward universal coalescence models for antideuteron production
Mattia di Mauro, Jordan Koechler, Lorenzo Stefanuto +3
Cosmic-ray (CR) antinuclei, especially antideuteron and antihelium-3 nuclei , are among the most promising messengers for indirect dark ma…
Leptophilic dark matter in models: a solution to the Fermi-LAT Galactic Center Excess consistent with cosmological and laboratory observations
Jordan Koechler, Mattia Di Mauro
The particle origin of dark matter (DM) remains elusive despite decades of direct, indirect, and collider searches. Several groups have reported a -ray excess toward the Galacti…
A Robust Determination of Antinuclei Production from Dark Matter via Weakly Decaying Beauty Hadrons
Mattia Di Mauro, Adil Jueid, Jordan Koechler +1
Recently, the Alpha Magnetic Spectrometer (AMS-02) Collaboration presented tentative evidence for the detection of cosmic antihelion-3 () events, alongside a…
Phenomenology of dark matter indirect detection
Jordan Koechler
In this thesis, we present a comprehensive and pedagogical overview of dark matter (DM). Chapter 1 discusses the main evidences for its existence, its properties, and potential can…
Refining Galactic primordial black hole evaporation constraints
Pedro De la Torre Luque, Jordan Koechler, Shyam Balaji
We revisit the role of primordial black holes (PBHs) as potential dark matter (DM) candidates, particularly focusing on light asteroid-mass PBHs. These PBHs are expected to emit pa…
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…
X-rays constraints on sub-GeV Dark Matter
Jordan Koechler
We present updated constraints on 'light' Dark Matter (DM) particles with masses between 1 MeV and 5 GeV. In this range, we can expect DM-produced pairs to up-scatter low-e…
Putting all the X in one basket: Updated X-ray constraints on sub-GeV Dark Matter
Marco Cirelli, Nicolao Fornengo, Jordan Koechler +2
Sub-GeV dark matter particles can annihilate or decay producing e^\pm pairs which upscatter the low-energy photon fields in the Galaxy and generate an X-ray emission (via the Inver…
