Unveiling the dark matter nature with reionization relics
Yao Zhang, Paulo Montero-Camacho, Catalina Morales-Gutiérrez +3
Dark matter constitutes roughly one-fourth of the Universe, yet its physical nature remains unknown. Warm dark matter (WDM), a class of dark matter candidates, has non-negligible v…
Weibel Instability-Driven Seed Magnetic Fields during Reionization
Jorie McDermott, Manami Roy, Christopher M. Hirata
Cosmological reionization was a highly out-of-equilibrium event that affected every parcel of the intergalactic medium, making it a candidate for astrophysical generation of interg…
Investigating the Gamma-Ray Emission from Explosive Dispersal Outflows with Fermi-LAT
Paarmita Pandey, Stephen C. Lenker, Laura A. Lopez +6
We present the first systematic study of explosive dispersal outflows (EDOs) as potential sources of high-energy emission in the Milky Way. EDOs are energetic outflows produced dur…
Prospects for detecting proto-neutron star rotation and spindown using supernova neutrinos
Tejas Prasanna, Todd A. Thompson, Christopher Hirata
After a successful supernova, a proto-neutron star (PNS) cools by emitting neutrinos on s timescales. Provided that there are neutrino emission `hot-spots' or `cold-sp…
