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 ...
Time dependent hadronic modeling of flat spectrum radio quasars
(American Astronomical Society, 2015)
We introduce a new time-dependent lepto-hadronic model for blazar emission that takes into account the radiation
emitted by secondary particles, such as pions and muons, from photo hadronic interactions. Starting from ...
Discovery of TeV y-ray emission from PKS 0447-439 and derivation of an upper limit on its redshift
(EDP Sciences, 2013)
Very high-energy γ-ray emission from PKS 0447−439 was detected with the H.E.S.S. Cherenkov telescope array in December 2009. This blazar is one of the brightest extragalactic objects in the Fermi bright source list and has ...
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 ...
A multiwavelength view of the flaring state of PKS 2155-304 in 2006
(EDP Sciences, 2012)
Context: Multiwavelength (MWL) observations of the blazar PKS 2155-304 during two weeks in July and August 2006, the period when two exceptional flares at very high energies (VHE, E ≳ 100 GeV) occurred, provide a detailed ...
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 ...
Synchrotron polarization in blazars
(IOP Publishing, 2014)
We present a detailed analysis of time- and energy-dependent synchrotron polarization signatures in a shock-in-jet model for γ-ray blazars. Our calculations employ a full three-dimensional radiation transfer code, assuming ...
Radio to gamma-ray variability study of blazar S5 0716+714
(EDP Sciences, 2013)
We present the results of a series of radio, optical, X-ray, and γ-ray observations of the BL Lac object S50716+714 carried out between April 2007 and January 2011. The multifrequency observations were obtained using several ...
