Asteroid-mass Primordial Black Holes as Dark Matter from Supersymmetry
Andrea Boccia, Marco Chianese
We study the formation of asteroid-mass Primordial Black Holes (PBHs) as a dark matter candidate in supersymmetric extensions of the Standard Model. We show that the presence of he…
Exploring memory-burdened primordial black holes with ultra-high-energy cosmic-rays
Antonio Ambrosone, Marco Chianese, Carmelo Evoli
Quantum backreaction effects may quench Hawking evaporation through a ``memory burden'', allowing primordial black holes (PBHs) with formation masses well below $10^{15}~\mathrm{g}…
Probing super-heavy dark matter with ultra-high-energy gamma rays
Marco Chianese, Ninetta Saviano, Sara Cesare +4
We refine the constraints on the lifetime of decaying super-heavy dark matter particles (SHDM), with masses ranging from to GeV, by analyzing ultra-high-energy (UH…
Cosmic-ray cooling by dark matter in astrophysical jets
Dimitrios Kantzas, Francesca Calore, Marco Chianese
Astrophysical jets from powerful active galactic nuclei (AGN) have recently been proposed as promising probes of dark matter (DM) in the sub-GeV mass range. AGN launch relativistic…
Constraints on heavy decaying dark matter from 570 days of LHAASO observations
The LHAASO Collaboration, Zhen Cao, F. Aharonian +276
The Kilometer Square Array~(KM2A) of the Large High Altitude Air Shower Observatory (LHAASO) aims at surveying the northern gamma-ray sky at energies above 10 TeV with unprecedente…
Fermionic sub-GeV Dark Matter from evaporating Primordial Black Holes at DarkSide-50
50 Collaboration, P. Agnes, I. F. Albuquerque +125
We present a search for boosted dark matter from Primordial Black Holes (PBH) evaporation using the DarkSide-50 ionization-signal-only dataset corresponding to the experiment's ($1…
