Fermi-LAT Observations of the Gamma-ray Burst GRB 130427A
LAT collaboration, GBM collaboration
The observations of the exceptionally bright gamma-ray burst (GRB) 130427A by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope provide constraints on the nature…
Impulsive and Long Duration High-Energy Gamma-ray Emission From the Very Bright 2012 March 7 Solar Flares
LAT collaboration
The Fermi Large Area Telescope (LAT) observed two bright X-class solar flares on 2012 March 7, and detected gamma-rays up to 4 GeV. We detected gamma-rays both during the impulsive…
Search for Gamma-ray Emission from X-ray Selected Seyfert Galaxies with Fermi-LAT
LAT Collaboration
We report on a systematic investigation of the gamma-ray properties of 120 hard X-ray-selected Seyfert galaxies classified as `radio-quiet' objects, utilizing the three-year accumu…
Measurement of separate cosmic-ray electron and positron spectra with the Fermi Large Area Telescope
The Fermi LAT Collaboration, M. Ackermann, M. Ajello +148
We measured separate cosmic-ray electron and positron spectra with the Fermi Large Area Telescope. Because the instrument does not have an onboard magnet, we distinguish the two sp…
Constraining Dark Matter Models from a Combined Analysis of Milky Way Satellites with the Fermi Large Area Telescope
LAT Collaboration, M. Ackermann, M. Ajello +150
Satellite galaxies of the Milky Way are among the most promising targets for dark matter searches in gamma rays. We present a search for dark matter consisting of weakly interactin…
Detection of a spectral break in the extra hard component of GRB 090926A
Fermi-LAT, Fermi-GBM collaborations
We report on the observation of the bright, long gamma-ray burst, GRB 090926A, by the Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) instruments on board the \Fermi\…
Detection of the Small Magellanic Cloud in gamma-rays with Fermi/LAT
LAT collaboration
The flux of gamma rays with energies >100MeV is dominated by diffuse emission from CRs illuminating the ISM of our Galaxy through the processes of Bremsstrahlung, pion production a…
Fermi Large Area Telescope Observations of Misaligned AGN
LAT Collaboration
Analysis is presented on 15 months of data taken with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope for 11 non-blazar AGNs, including 7 FRI radio galaxies a…
Fermi Gamma-ray Imaging of a Radio Galaxy
LAT Collaboration
The Fermi Gamma-ray Space Telescope has detected the gamma-ray glow emanating from the giant radio lobes of the radio galaxy Centaurus A. The resolved gamma-ray image shows the lob…
Discovery of Pulsed -rays from PSR J0034-0534 with the Fermi LAT: A Case for Co-located Radio and -ray Emission Regions
The Fermi LAT Collaboration, Pulsar Timing Consortium
Millisecond pulsars (MSPs) have been firmly established as a class of gamma-ray emitters via the detection of pulsations above 0.1 GeV from eight MSPs by the Fermi Large Area Teles…
Spectral Properties of Bright Fermi-detected Blazars in the Gamma-ray Band
LAT Collaboration
The gamma-ray energy spectra of bright blazars of the LAT Bright AGN Sample (LBAS) are investigated using Fermi-LAT data. Spectral properties (hardness, curvature and variability)…
Fermi Large Area Telescope Observations of the Cosmic-Ray Induced gamma-ray Emission of the Earth's Atmosphere
LAT collaboration
We report on measurements of the cosmic-ray induced gamma-ray emission of Earth's atmosphere by the Large Area Telescope onboard the Fermi Gamma-ray Space Telescope. The LAT has ob…
Fermi LAT Observations of LS 5039
The Fermi LAT collaboration
The first results from observations of the high mass X-ray binary LS 5039 using the Fermi Gamma-ray Space Telescope data between 2008 August and 2009 June are presented. Our result…
