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 ...
HESS and Fermi-LAT discovery of γ-rays from the blazar 1ES 1312-423
(Oxford Univ Press, 2013)
A deep observation campaign carried out by the High Energy Stereoscopic System (HESS) on Centaurus A enabled the discovery of γ-rays from the blazar 1ES 1312−423, 2° away from the radio galaxy. With a differential flux at ...
Multi-band implications of external-IC flares
(Elsevier, 2015)
Very fast variability on scales of minutes is regularly observed in Blazars. The assumption that these flares
are emerging from the dominant emission zone of the very high energy (VHE) radiation within the jet
challenges ...
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 ...
Hadronic models of blazars require a change of the accretion paradigm
(Oxford University Press, 2015)
We study hadronic models of broad-band emission of jets in radio-loud active galactic nuclei, and their implications for the accretion in those sources. We show that the models that account for broad-band spectra of blazars ...
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 ...
Seed photon fields of blazars in the internal shock scenario
(IOP Publishing, 2014)
We extend our approach of modeling spectral energy distribution (SED) and light curves of blazars to include external Compton (EC) emission due to inverse Compton scattering of an external anisotropic target radiation ...
