X-ray and gamma-ray polarization in leptonic and hadronic jet models of blazars
(IOP Science, 2013)
We present a theoretical analysis of the expected X-ray and γ-ray polarization signatures resulting from synchrotron self-Compton emission in leptonic models compared to the polarization signatures from proton synchrotron ...
Studies of active galactic nuclei with CTA
(Elsevier, 2013)
In this paper, we review the prospects for studies of active galactic nuclei (AGN) using the envisioned
future Cherenkov Telescope Array (CTA). This review focuses on jetted AGN, which constitute the vast
majority of AGN ...
Discovery of a new TeV gamma-ray source: Ver J0521+211
(IOP Science, 2013)
We report the detection of a new TeV gamma-ray source, VER J0521+211, based on observations made with the VERITAS imaging atmospheric Cherenkov Telescope Array. These observations were motivated by the discovery of a cluster ...
Discovery of very high energy γ-ray emission from the BL Lacertae object PKS 0301-243 with H.E.S.S.
(EDP Sciences, 2013)
The active galactic nucleus PKS 0301−243 (z = 0.266) is a high-synchrotron-peaked BL Lac object that is detected at high energies (HE, 100 MeV < E < 100 GeV) by Fermi/LAT. This paper reports on the discovery of PKS 0301−243 ...
Long term observations of B2 1215+30 with Veritas
(IOP Science, 2013)
We report on VERITAS observations of the BL Lac object B2 1215+30 between 2008 and 2012. During this period, the source was detected at very high energies (VHEs; E > 100 GeV) by VERITAS with a significance of 8.9σ and ...
Leptonic and hadronic modeling of Fermi-detected blazars
(IOP Science, 2013)
We describe new implementations of leptonic and hadronic models for the broadband emission from relativistic jets in active galactic nuclei in a temporary steady state. For the leptonic model, a temporary equilibrium between ...
Multiwavelength observations and modeling of 1ES 1959+650 in low flux state
(IOP Science, 2013)
We report on the VERITAS observations of the high-frequency peaked BL Lac object 1ES 1959+650 in the period 2007–2011. This source is detected at TeV energies by VERITAS at 16.4 standard deviation (σ) significance in 7.6 ...
The 72-h WEBT microvariability observation of blazar S5 0716+714 in 2009
(EDP Sciences, 2013)
Context. The international Whole Earth Blazar Telescope (WEBT) consortium planned and carried out three days of intensive micro-variability observations of S5 0716+714 from February 22, 2009 to February 25, 2009. This ...
The awakening of BL Lacertae: observations by Fermi, Swift and the GASP-WEBT
(Oxford University Press, 2013)
Since the launch of the Fermi satellite, BL Lacertae has been moderately active at γ-rays and optical frequencies until 2011 May, when the source started a series of strong flares. The exceptional optical sampling achieved ...
Gamma-ray observational properties of TeV-detected blazars
(IOP Science, 2013)
The synergy between the Fermi-LAT and ground-based Cherenkov telescope arrays gives us the opportunity for the first time to characterize the high-energy emission from blazars over 5 decades in energy, from 100 MeV to 10 ...
