Limits on primordial black holes from the extragalactic gamma-ray background; current status and future projections
Ilias Cholis, Iason Krommydas, John Carlini
Primordial black holes (PBHs), possibly formed from the collapse of early universe perturbations, will evaporate via Hawking radiation with a lifetime comparable to the age of the…
Scrutinizing the Isotropic Gamma-Ray Background in Search of Dark Matter
Ilias Cholis, Iason Krommydas
The isotropic gamma-ray background (IGRB), measured by the Fermi Large Area Telescope, is the result of several classes of extragalactic astrophysical sources. Those sources includ…
Revisiting GeV-scale annihilating dark matter with the AMS-02 positron fraction
Iason Krommydas, Ilias Cholis
Antimatter cosmic-rays are used to probe new phenomena in physics, including dark matter annihilation. We use the cosmic-ray positron fraction spectrum by the Alpha Magnetic Spectr…
Possible counterpart signal of the Fermi bubbles at the cosmic-ray positrons
Ilias Cholis, Iason Krommydas
The inner galaxy has hosted cosmic-ray burst events including those responsible for the gamma-ray Fermi bubbles and the eROSITA bubbles in X-rays. In this work, we study the AMS-02…
Utilizing cosmic-ray positron and electron observations to probe the averaged properties of Milky Way pulsars
Ilias Cholis, Iason Krommydas
Pulsars have long been studied in the electromagnetic spectrum. Their environments are rich in high-energy cosmic-ray electrons and positrons likely enriching the interstellar medi…
