Highlight Talk: Recent Results from VERITAS
R. A. Ong, V. A. Acciari, T. Arlen +79
VERITAS is a state-of-the-art ground-based gamma-ray observatory that operates in the very high-energy (VHE) region of 100 GeV to 50 TeV. The observatory consists of an array of fo…
Simulation of relativistic shocks and associated radiation
K. -I. Nishikawa, J. Niemiec, M. Medvedev +9
Using our new 3-D relativistic electromagnetic particle (REMP) code parallelized with MPI, we investigated long-term particle acceleration associated with a relativistic electron-p…
Fermi Constrains Dark Matter Origin of High Energy Positron Anomaly
Martin Pohl, David Eichler
Fermi measurements of the high-latitude gamma-ray background strongly constrain a decaying-dark-matter origin for the 1--100 GeV Galactic positron anomaly measured with PAMELA. Inv…
Aperiodic magnetic turbulence produced by relativistic ion beams
Jacek Niemiec, Martin Pohl, Antoine Bret +1
Magnetic-field generation by a relativistic ion beam propagating through an electron-ion plasma along a homogeneous magnetic field is investigated with 2.5D high-resolution particl…
A connection between star formation activity and cosmic rays in the starburst galaxy M 82
V. A. Acciari, E. Aliu, T. Arlen +89
Although Galactic cosmic rays (protons and nuclei) are widely believed to be dominantly accelerated by the winds and supernovae of massive stars, definitive evidence of this origin…
VERITAS Upper Limit on the VHE Emission from the Radio Galaxy NGC 1275
VERITAS Collaboration, V. A. Acciari, E. Aliu +88
The recent detection by the Fermi gamma-ray space telescope of high-energy gamma-rays from the radio galaxy NGC 1275 makes the observation of the very high energy (VHE: E > 100 GeV…
