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…
MAGIC upper limits on the GRB 090102 afterglow
MAGIC Collaboration, J. Aleksić, S. Ansoldi +160
Indications of a GeV component in the emission from GRBs are known since the EGRET observations during the 1990's and they have been confirmed by the data of the Fermi satellite. T…
Fermi LAT and WMAP observations of the supernova remnant HB 21
G. Pivato, J. Hewitt, L. Tibaldo +8
We present the analysis of Fermi Large Area Telescope (LAT) -ray observations of HB~21 (G89.0+4.7). We detect significant -ray emission associated with the remnant: the flux…
Dark Matter Constraints from Observations of 25 Milky Way Satellite Galaxies with the Fermi Large Area Telescope
LAT Collaboration, M. Ackermann, A. Albert +119
The dwarf spheroidal satellite galaxies of the Milky Way are some of the most dark-matter-dominated objects known. Due to their proximity, high dark matter content, and lack of ast…
Determination of the Point-Spread Function for the Fermi Large Area Telescope from On-orbit Data and Limits on Pair Halos of Active Galactic Nuclei
LAT Collaboration
The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope is a pair-conversion telescope designed to detect photons with energies from 20 MeV to > 300 GeV. The pre-laun…
PSR J2021+4026 in the Gamma Cygni region: the first variable gamma-ray pulsar seen by the Fermi LAT
LAT collaboration
Long-term monitoring of PSR J2021+4026 in the heart of the Cygnus region with the Fermi Large Area Telescope (LAT) unveiled a sudden decrease in flux above 100 MeV over a time scal…
Search for long-lived gravitational-wave transients coincident with long gamma-ray bursts
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +875
Long gamma-ray bursts (GRBs) have been linked to extreme core-collapse supernovae from massive stars. Gravitational waves (GW) offer a probe of the physics behind long GRBs. We inv…
Gravitational waves from known pulsars: results from the initial detector era
J. Aasi, J. Abadie, B. P. Abbott +892
We present the results of searches for gravitational waves from a large selection of pulsars using data from the most recent science runs (S6, VSR2 and VSR4) of the initial generat…
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…
Rapid and multi-band variability of the TeV-bright active nucleus of the galaxy IC 310
The MAGIC Collaboration, J. Aleksić, L. A. Antonelli +161
Context. The radio galaxy IC 310 has recently been identified as a gamma-ray emitter based on observations at GeV energies with Fermi-LAT and at very high energies (VHE, E>100GeV)…
The Second Fermi Large Area Telescope Catalog of Gamma-ray Pulsars
