Electromagnetic field solver for QED polarization in super-strong magnetic fields of magnetar and laser plasmas
Mahmoud Alawashra, Jan Benáček, Martin Pohl +1
Super-strongly magnetized plasmas play a crucial role in extreme environments of magnetar and laboratory laser experiments, demanding comprehensive understanding of how quantum ele…
Kinetic simulations of non-relativistic high-Mach-number perpendicular shocks propagating in a turbulent medium
Karol Fulat, Artem Bohdan, Gabriel Torralba Paz +1
Strong non-relativistic shocks are known to accelerate particles up to relativistic energies. However, for Diffusive Shock Acceleration electrons must have a highly suprathermal en…
Magnetic field amplification by the Weibel instability at planetary and astrophysical high-Mach-number shocks
Artem Bohdan, Martin Pohl, Jacek Niemiec +5
Collisionless shocks are ubiquitous in the Universe and often associated with strong magnetic field. Here we use large-scale particle-in-cell simulations of non-relativistic perpen…
Very-High-Energy -Ray Observations of the Blazar 1ES 2344+514 with VERITAS
C. Allen, S. Archambault, A. Archer +79
We present very-high-energy -ray observations of the BL Lac object 1ES 2344+514 taken by the Very Energetic Radiation Imaging Telescope Array System (VERITAS) between 2007 and 2…
Evolution of Global Relativistic Jets: Collimations and Expansion with kKHI and the Weibel Instability
K. I Nishikawa, J. T. Frederiksen, A. Nordlund +10
One of the key open questions in the study of relativistic jets is their interaction with the environment. Here, we study the initial evolution of both electron-proton and electron…
The 2009 multiwavelength campaign on Mrk 421: Variability and correlation studies
MAGIC Collaboration, J. Aleksić, S. Ansoldi +270
We performed a 4.5-month multi-instrument campaign (from radio to VHE gamma rays) on Mrk421 between January 2009 and June 2009, which included VLBA, F-GAMMA, GASP-WEBT, Swift, RXTE…
Reacceleration of electrons in supernova remnants
M. Pohl, A. Wilhelm, I. Telezhinsky
The radio spectra of many shell-type supernova remnants show deviations from those expected on theoretical grounds. In this paper we determine the effect of stochastic reaccelerati…
The most powerful flaring activity from the NLSy1 PMN J0948+0022
F. D'Ammando, M. Orienti, J. Finke +73
We report on multifrequency observations performed during 2012 December-2013 August of the first narrow-line Seyfert 1 galaxy detected in gamma rays, PMN J0948+0022 ( = 0.5846).…
Parametric study of non-relativistic electrostatic shocks and the structure of their transition layer
ME Dieckmann, H Ahmed, G Sarri +5
Nonrelativistic electrostatic unmagnetized shocks are frequently observed in laboratory plasmas and they are likely to exist in astrophysical plasmas. Their maximum speed, expresse…
Radiation from accelerated particles in relativistic jets with shocks, shear-flow, and reconnection
K. -I. Nishikawa, P. Hardee, B. Zhang +11
We have investigated particle acceleration and shock structure associated with an unmagnetized relativistic jet propagating into an unmagnetized plasma. Strong magnetic fields gene…
Simulation of Relativistic Jets and Associated Self-consistent Radiation
K. -I. Nishikawa, E. J. Choi, K. Min +11
lasma instabilities excited in collisionless shocks are responsible for particle acceleration. We have investigated the particle acceleration and shock structure associated with an…
Gamma-ray observations of the Be/pulsar binary 1A 0535+262 during a giant X-ray outburst
VERITAS collaboration, V. A. Acciari, E. Aliu +73
Giant X-ray outbursts, with luminosities of about erg s, are observed roughly every 5 years from the nearby Be/pulsar binary 1A 0535+262. In this article, we pres…
Radiation from relativistic shocks with turbulent magnetic fields
K. -I. Nishikawa, J. Niemiec, M. Medvedev +10
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…
