A rotating GUP black hole: metric, shadow, and bounds on quantum parameters

Federica Fragomeno, Samantha Hergott, Saeed Rastgoo +1

Recently, for the first time, a metric of a static spherically symmetric generalized uncertainty inspired quantum black hole was derived. We apply the modified Newman-Janis algorit…

Dark matter annihilation signals from the Large Magellanic Cloud and its impact on the Milky Way

Evan Vienneau, Evan Batteas, Addy J. Evans +3

We study the dark matter (DM) annihilation signals from the Large Magellanic Cloud (LMC) and the impact of the LMC on the DM annihilation signals from the Milky Way (MW) halo, usin…

Enhancements in velocity-dependent dark matter annihilation in Galactic subhalos

Odelia V. Hartl, Evan Vienneau, Evan Batteas +3

We examine velocity-dependent dark matter annihilation in subhalos using a sample of six Milky Way-like galaxies from the Aurgia simulation suite. We quantify the enhancement in th…

Dark matter decay signals in cosmic filaments

Elena Pinetti, Evan Vienneau, Nassim Bozorgnia

Cosmic filaments form the backbone of the cosmic web, yet their properties and evolution remain uncertain. Using the EAGLE hydrodynamical simulations, we investigate the dark matte…

A generalized uncertainty-inspired quantum black hole

Federica Fragomeno, Douglas M. Gingrich, Samantha Hergott +2

We derive the full spacetime metric of a generalized uncertainty-inspired quantum black hole. We examine a previous model of the interior in this approach and show that extending i…
