The 1st Fermi Lat Supernova Remnant Catalog
Fabio Acero, Markus Ackermann, Marco Ajello +156
To uniformly determine the properties of supernova remnants (SNRs) at high energies, we have developed the first systematic survey at energies from 1 to 100 GeV using data from the…
Fermi-LAT Observations of High-Energy Gamma-Ray Emission Toward the Galactic Center
LAT Collaboration
The Fermi Large Area Telescope (LAT) has provided the most detailed view to date of the emission towards the Galactic centre (GC) in high-energy gamma-rays. This paper describes th…
Multiwavelength Evidence for Quasi-periodic Modulation in the Gamma-ray Blazar PG 1553+113
The Fermi LAT collaboration, M. Ackermann, M. Ajello +139
We report for the first time a gamma-ray and multi-wavelength nearly-periodic oscillation in an active galactic nucleus. Using the Fermi Large Area Telescope (LAT) we have discover…
Galactic cosmic ray propagation models using Picard
Ralf Kissmann, Olaf Reimer, Andrew W. Strong
We present results obtained from our newly developed Galactic cosmic-ray transport code PICARD, that solves the cosmic-ray transport equation. This code allows for the computation…
Search for extended gamma-ray emission from the Virgo galaxy cluster with Fermi-LAT
M. Ackermann, M. Ajello, A. Albert +118
Galaxy clusters are one of the prime sites to search for dark matter (DM) annihilation signals. Depending on the substructure of the DM halo of a galaxy cluster and the cross secti…
Observations of the Crab Nebula with H.E.S.S. Phase II
M. Holler, D. Berge, C. van Eldik +7
The High Energy Stereoscopic System (H.E.S.S.) phase I instrument was an array of four mirror area Imaging Atmospheric Cherenkov Telescopes (IACTs) that has ver…
Deep view of the Large Magellanic Cloud with 6 years of Fermi-LAT observations
LAT Collaboration
The nearby Large Magellanic Cloud (LMC) provides a rare opportunity of a spatially resolved view of an external star-forming galaxy in gamma-rays. The LMC was detected at 0.1-100Ge…
2FHL: The Second Catalog of Hard Fermi-LAT Sources
LAT Collaboration
We present a catalog of sources detected above 50 GeV by the {\it Fermi}-Large Area Telescope (LAT) in 80 months of data. The newly delivered Pass 8 event-level analysis allows the…
Search for Gamma-ray Production in Supernovae Located in a Dense Circumstellar Medium with the Fermi-LAT
A. Franckowiak, K. Murase, E. O. Ofek
Supernovae (SNe) exploding in a dense circumstellar medium (CSM) are predicted to accelerate cosmic rays in collisionless shocks and emit GeV gamma rays and TeV neutrinos on a time…
Search for gamma-ray emission from the Coma Cluster with six years of Fermi-LAT data
LAT Collaboration, Y. Rephaeli
We present results from γ-ray observations of the Coma cluster incorporating 6 years of Fermi-LAT data and the newly released {\emph{Pass 8}} event-level analysis. Our analysis of…
Search for Early Gamma-ray Production in Supernovae Located in a Dense Circumstellar Medium with the Fermi LAT
M. Ackermann, I. Arcavi, L. Baldini +108
Supernovae (SNe) exploding in a dense circumstellar medium (CSM) are hypothesized to accelerate cosmic rays in collisionless shocks and emit GeV gamma rays and TeV neutrinos on a t…
Propagation in 3D spiral-arm cosmic-ray source distribution models and secondary particle production using PICARD
Ralf Kissmann, Michael Werner, Olaf Reimer +1
We study the impact of possible spiral-arm distributions of Galactic cosmic-ray sources on the flux of various cosmic-ray nuclei throughout our Galaxy. We investigate model cosmic-…
The first full orbit of Eta Carinae seen by Fermi
K. Reitberger, A. Reimer, O. Reimer +1
The binary system eta Carinae has completed its first 5.54y orbit since the beginning of science operation of the Fermi Large Area Telescope (LAT). We are now able to investigate t…
