Dark matter mounds from the collapse of supermassive stars: a general-relativistic analysis
Roberto Caiozzo, Gianfranco Bertone, Piero Ullio +3
Recent work has highlighted the importance of a fully relativistic treatment of the dephasing of gravitational waves induced by dark-matter overdensities in extreme mass-ratio insp…
The self-confinement of electrons and positrons from dark matter
Marco Regis, Michael Korsmeier, Gianni Bernardi +3
Radiative emissions from electrons and positrons generated by dark matter (DM) annihilation or decay are one of the most investigated signals in indirect searches of WIMPs. Ideal t…
Neutron Star Heating in Dark Matter Models for Muon g-2 with Scalar Lepton Partners up to the TeV Scale
Jan Tristram Acuña, Patrick Stengel, Piero Ullio
We investigate the kinetic heating of neutron stars due to dark matter scattering in minimal models with scalar lepton partners mediating interactions which can account for the ano…
Blazar-Boosted Dark Matter at Super-Kamiokande
Alessandro Granelli, Piero Ullio, Jin-Wei Wang
Dark matter particles near the center of a blazar, after being accelerated by the elastic collisions with relativistic electrons and protons in the blazar jet, can be energetic eno…
A Minimal Dark Matter Model for Muon g-2 with Scalar Lepton Partners up to the TeV Scale
Jan Tristram Acuña, Patrick Stengel, Piero Ullio
The E989 experiment at the Fermi National Laboratory reported a 4.2 discrepancy between the measured magnetic dipole moment of the muon, and its prediction in the Standard Model…
Direct Detection Constraints on Blazar-Boosted Dark Matter
Jin-Wei Wang, Alessandro Granelli, Piero Ullio
We explore the possibility that relativistic protons in the extremely powerful jets of blazars may boost via elastic collisions the dark matter particles in the surroundings of the…
