γ-Ray and ultra-high energy neutrino background suppression due to solar radiation

Physics Letters B, 2023
The Sun emits copious amounts of photons and neutrinos in an approximately spatially isotropic distribution. Diffuse γ-rays and ultra-high energy (UHE) neutrinos from extragalactic sources may subsequently interact and annihilate with the emitted solar ...

Fermi Gamma-Ray Space Telescope

, 2022
The Fermi Gamma-ray Space Telescope, a key mission in multiwavelength and multimessenger studies, has been surveying the gamma-ray sky from its low-Earth orbit since 2008. Its two scientific instruments, the Gamma-ray Burst Monitor (GBM) and the Large Area Telescope (LAT), cover 8 orders of magnitude in photon energy.

The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars

The Astrophysical Journal, 2023
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected

Explaining the GeV excess with exploding black holes

Physics Letters B, 2023
Black holes may form in present-day collapse of microscopic structures of dark matter. We show that, if microstructure black holes (MSBH) with mass m∼1013 g are produced, the spectrum of gamma rays from their evaporation agrees remarkably well with the ...

Pulsar timing for theFermigamma-ray space telescope [PDF]

Astronomy & Astrophysics, 2008
We describe a comprehensive pulsar monitoring campaign for the Large Area Telescope (LAT) on the {\em Fermi Gamma-ray Space Telescope} (formerly GLAST). The detection and study of pulsars in gamma rays give insights into the populations of neutron stars and supernova rates in the Galaxy, into particle acceleration mechanisms in neutron star ...
