Marginal Role of the Electrostatic Instability in the GeV-scale Cascade Flux from 1ES 0229+200
Mahmoud Alawashra, Ievgen Vovk, Martin Pohl
Relativistic pair beams produced in the intergalactic medium (IGM) by TeV gamma rays from blazars are expected to generate a detectable GeV-scale electromagnetic cascade, yet this…
Stochastic re-acceleration and magnetic-field damping in Tycho's supernova remnant
A. Wilhelm, I. Telezhinsky, V. V. Dwarkadas +1
A number of studies suggest that shock acceleration with particle feedback and very efficient magnetic-field amplification combined with Alfvénic drift are needed to explain the ra…
Non-thermal emission from the reverse shock of the youngest galactic Supernova remnant G1.9+0.3
R. Brose, I. Sushch, M. Pohl +3
Context. The youngest Galactic supernova remnant G1.9+0.3 is an interesting target for next generation gamma-ray observatories. So far, the remnant is only detected in the radio an…
Multiband variability studies and novel broadband SED modeling of Mrk 501 in 2009
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +290
We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1 which inc…
Acceleration of cosmic rays by young core-collapse supernova remnants
I. Telezhinsky, V. V. Dwarkadas, M. Pohl
Context. Supernova remnants (SNRs) are thought to be the primary candidates for the sources of Galactic cosmic rays. According to the diffusive shock acceleration theory, SNR shock…
Time-Dependent Escape of Cosmic Rays from Supernova Remnants, and their Interaction with Dense Media
I. Telezhinsky, V. V. Dwarkadas, M. Pohl
Context. Supernova remnants (SNRs) are thought to be the main source of Galactic cosmic rays (CRs) up to the "knee" in CR spectrum. During the evolution of a SNR, the bulk of the C…
Veritas: Status c. 2009
T. C. Weekes, the VERITAS Collaboration
VERITAS is a ground-based gamma-ray observatory that uses the imaging atmospheric Cherenkov technique and operates in the very high-energy (VHE) region of the gamma- ray spectrum f…
