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…

The First Pulse of the Extremely Bright GRB 130427A: A Test Lab for Synchrotron Shocks

R. Preece, J. Michael Burgess, A. von Kienlin +156

Gamma-ray burst (GRB) 130427A is one of the most energetic GRBs ever observed. The initial pulse up to 2.5 s is possibly the brightest well-isolated pulse observed to date. A fine…

Response to "Stray-light correction in 2D spectroscopy" by R. Schlichenmaier and M. Franz

G. B. Scharmer

We discuss a recent paper by Schlichenmaier & Franz (SF; 2013, A&A, 555, A84), in which the claim is made that the penumbral dark downflows detected for the first time with the Swe…

Search for cosmic-ray induced gamma-ray emission in Galaxy Clusters

M. Ackermann, M. Ajello, A. Albert +123

Current theories predict relativistic hadronic particle populations in clusters of galaxies in addition to the already observed relativistic leptons. In these scenarios hadronic in…

Associating long-term gamma-ray variability with the superorbital period of LS I 61 303

LAT Collaboration

Gamma-ray binaries are stellar systems for which the spectral energy distribution (discounting the thermal stellar emission) peaks at high energies. Detected from radio to TeV gamm…

Constraints on the Galactic Population of TEV Pulsar Wind Nebulae Using Fermi Large Area Telescope Observations

F. Acero, M. Ackermann, M. Ajello +155

Pulsar wind nebulae (PWNe) have been established as the most populous class of TeV gamma-ray emitters. Since launch, the Fermi Large Area Telescope (LAT)identified five high-energy…

Search for Gamma-ray Spectral Lines with the Fermi Large Area Telescope and Dark Matter Implications

LAT Collaboration

Weakly Interacting Massive Particles (WIMPs) are a theoretical class of particles that are excellent dark matter candidates. WIMP annihilation or decay may produce essentially mono…

The Fermi All-sky Variability Analysis: A list of flaring gamma-ray sources and the search for transients in our Galaxy

LAT Collaboration

In this paper we present the Fermi All-sky Variability Analysis (FAVA), a tool to systematically study the variability of the gamma-ray sky measured by the Large Area Telescope (LA…

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…

Detection of the Characteristic Pion-Decay Signature in Supernova Remnants

LAT collaboration, M. Ackermann, M. Ajello +167

Cosmic rays are particles (mostly protons) accelerated to relativistic speeds. Despite wide agreement that supernova remnants (SNRs) are the sources of galactic cosmic rays, unequi…
