  1. 216. 20 GeV halo-like gamma-ray excess: dark matter annihilation?

    Fifteen years of the Fermi Large Area Telescope (LAT) data in the halo region of the Milky Way (MW) are analyzed to search for gamma rays from dark matter annihilation. Gamma-ray maps within the region of interest (|l| < 60 deg, 10 < |b| < 60 deg) are modeled using point sources, the GALPROP models of cosmic-ray interactions, isotropic background, and templates of Loop I and the Fermi bubbles,...

  2. 218. Vacuum relics in ultra-slow-roll inflation

    We study the formation of vacuum bubbles in ultra-slow-roll inflation. Our results show that these bubbles play a significant role in the dynamics of the system and provide an important contribution to the primordial black hole population, potentially accounting for a substantial fraction of dark matter.
