Recent Results from the Fermi Gamma-ray Space Telescope [PDF]

Proceedings of 35th International Conference of High Energy Physics — PoS(ICHEP 2010), 2011
The Fermi Gamma-ray Space Telescope, formerly named GLAST, is a mission in low-Earth orbit to observe gamma rays from the cosmos in the broad energy range from 20 MeV to >300 GeV, with supporting observations of gamma-ray bursts from 8 keV to 30 MeV. The

Source detection using a 3D sparse representation: application to the Fermi gamma-ray space telescope [PDF]

Astronomy & Astrophysics, 2009
The multiscale variance stabilization Transform (MSVST) has recently been proposed for Poisson data denoising. This procedure, which is nonparametric, is based on thresholding wavelet coefficients. We present in this paper an extension of the MSVST to 3D

FermiGamma-ray Space Telescope Observations of the Gamma-ray Outburst from 3C454.3 in November 2010 [PDF]

Journal of Physics: Conference Series, 2012
The flat-spectrum radio quasar 3C454.3 underwent an extraordinary 5-day γ-ray outburst in November 2010 when the daily flux measured with the Fermi Large Area Telescope (LAT) at photon energies E > 100MeV reached (66±2) × 10−6ph cm−2s−1. This is a factor

Fermi observations of high-energy gamma-ray emission from GRB 080825C [PDF]

Astrophys.J.707:580-592,2009, 2009
The Fermi Gamma-ray Space Telescope (FGST) has opened a new high-energy window in the study of Gamma-Ray Bursts (GRBs). Here we present a thorough analysis of GRB 080825C, which triggered the Fermi Gamma-ray Burst Monitor (GBM), and was the first firm detection of a GRB by the Fermi Large Area Telescope (LAT).

Fermi Gamma-ray Space Telescope [PDF]

, 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.

Exclusion of Canonical Weakly Interacting Massive Particles by Joint Analysis of Milky Way Dwarf Galaxies with Data from the Fermi Gamma-Ray Space Telescope [PDF]

Physical Review Letters, 2011
Dwarf spheroidal galaxies are known to be excellent targets for the detection of annihilating dark matter. We present new limits on the annihilation cross section of weakly interacting massive particles based on the joint analysis of seven Milky Way ...
