Gamma rays from the quasar PKS 1441+25: story of an escape
A. U. Abeysekara, S. Archambault, A. Archer +103
Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the Universe. The det…
Multiwavelength Study of Quiescent States of Mrk 421 with Unprecedented Hard X-Ray Coverage Provided by NuSTAR in 2013
M. Baloković, D. Paneque, G. Madejski +305
We present coordinated multiwavelength observations of the bright, nearby BL Lac object Mrk 421 taken in 2013 January-March, involving GASP-WEBT, Swift, NuSTAR, Fermi-LAT, MAGIC, V…
A recent change in the optical and γ-ray polarization of the Crab nebula and pulsar
Paul Moran, Gillian Kyne, Christian Gouiffes +5
We report on observations of the polarization of optical and γ-ray photons from the Crab nebula and pulsar system using the Galway Astronomical Stokes Polarimeter (GASP), the Hubbl…
VLT polarimetry observations of PSR B0656+14
R. P. Mignani, P. Moran, A Shearer +5
Optical polarisation measurements are key tests for different models of the pulsar magnetosphere. Furthermore, comparing the relative orientation of the phase-averaged linear polar…
First NuSTAR Observations of Mrk 501 within a Radio to TeV Multi-Instrument Campaign
A. Furniss, K. Noda, S. Boggs +273
We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 1 April and 10 August 2013, including the first detailed characterization of the s…
VERITAS detection of -ray flaring activity from the BL Lac object 1ES 1727+502 during bright moonlight observations
S. Archambault, A. Archer, M. Beilicke +80
During moonlit nights, observations with ground-based Cherenkov telescopes at very high energies (VHE, GeV) are constrained since the photomultiplier tubes (PMTs) in the te…
Circular polarisation of synchrotron radiation in high magnetic fields
Diarmaid de Búrca, Andrew Shearer
The general model for incoherent synchrotron radiation has long been known, with the first theory being published by Westfold in and continued by Westfold and Legg in …
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…
