FERMI LARGE AREA TELESCOPE SECOND SOURCE CATALOG
We present the second catalog of high-energy γ-ray sources detected by the Large Area Telescope (LAT), the primary science instrument on the Fermi Gamma-ray Space Telescope (Fermi), derived from data…

- A. Abdo, M. Ajello, Zhirong Yang
- Physics
- 19 September 2013
This catalog summarizes 117 high-confidence ⩾0.1 GeV gamma-ray pulsar detections using three years of data acquired by the Large Area Telescope (LAT) on the Fermi satellite. Half are neutron stars…
Relativistic jet activity from the tidal disruption of a star by a massive black hole
- D. Burrows, J. Kennea, N. Gehrels
- PhysicsNature
- 1 August 2011
Observations of a bright X-ray flare from the extragalactic transient Swift J164449.3+573451 conclude that they have captured the onset of relativistic jet activity from a supermassive black hole.
THE SPECTRUM OF ISOTROPIC DIFFUSE GAMMA-RAY EMISSION BETWEEN 100 MeV AND 820 GeV
- T. A. C. M. Ackermann, M. Ajello, S. Zimmer
- PhysicsAstrophysical Journal
- 14 October 2014
The γ-ray sky can be decomposed into individually detected sources, diffuse emission attributed to the interactions of Galactic cosmic rays with gas and radiation fields, and a residual all-sky…
GeV OBSERVATIONS OF STAR-FORMING GALAXIES WITH THE FERMI LARGE AREA TELESCOPE
- F. C. M. Ackermann, M. Ajello, Z. Yang
- PhysicsAstrophysical Journal
- 6 June 2012
Recent detections of the starburst galaxies M82 and NGC 253 by gamma-ray telescopes suggest that galaxies rapidly forming massive stars are more luminous at gamma-ray energies compared to their…
Searching for Dark Matter Annihilation from Milky Way Dwarf Spheroidal Galaxies with Six Years of Fermi Large Area Telescope Data.
- M. Ackermann, A. Albert, S. Zimmer
- PhysicsPhysical Review Letters
- 9 March 2015
The dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are some of the most dark matter (DM) dominated objects known. We report on γ-ray observations of Milky Way dSphs based on six years…
THE THIRD CATALOG OF ACTIVE GALACTIC NUCLEI DETECTED BY THE FERMI LARGE AREA TELESCOPE
- M. Ackermann, M. Ajello, S. Zimmer
- Physics
- 24 January 2015
The third catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT (3LAC) is presented. It is based on the third Fermi-LAT catalog (3FGL) of sources detected between 100 MeV and 300 GeV…
Detection of the Characteristic Pion-Decay Signature in Supernova Remnants
- M. Ackermann, M. Ajello, S. Zimmer
- PhysicsScience
- 14 February 2013
The characteristic pion-decay feature is detected in the gamma-ray spectra of two SNRs, IC 443 and W44, with the Fermi Large Area Telescope, providing direct evidence that cosmic-ray protons are accelerated in SNRs.
The X-ray counterpart to the gravitational-wave event GW170817
The detection of X-ray emission at a location coincident with the kilonova transient provides the missing observational link between short γ-ray bursts and gravitational waves from neutron-star mergers, and gives independent confirmation of the collimated nature of the γ,ray-burst emission.
FERMI-LAT OBSERVATIONS OF THE DIFFUSE γ-RAY EMISSION: IMPLICATIONS FOR COSMIC RAYS AND THE INTERSTELLAR MEDIUM
- M. Ackermann, M. Ajello, S. Zimmer
- Physics
- 1 May 2012
The γ-ray sky >100 MeV is dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of these diffuse emissions…
