Discerning the -ray emitting region in the flat spectrum radio quasars
Y. G. Zheng, C. Y. Yang, L. Zhang +1
A model-dependent method is proposed to determine the location of the -ray emitting region for a given flat spectrum radio quasar (FSRQ). In the model, the extra-relativistic el…
Evidence for the Secondary Emission as the Origin of Hard Spectra in TeV Blazars
Y. G. Zheng, T. Kang
We develop a model for a possible origin of hard very high energy spectra from a distant blazar. In the model, both the primary photons produced in the source and secondary photons…
Rapid TeV Flaring in Markarian 501
Y. G. Zheng, L. Zhang
We investigate rapid TeV flaring in markarian 501 in the frame of a time-dependent one-zone synchrotron self-Compton (SSC) model. Inthis model, electrons are accelerated to extra-r…
X-ray and gamma-ray variability of Mrk 421
Y. G. Zheng, S. J. Kang, J. Li
We present an ordinary case in the momentum diffusion equation for the electron spectrum evolution and investigate the energy spectra and time dependent properties of flare in Mrk…
Modelling the -ray variability of 3C 273
Y. G. Zheng, L. Zhang, B. R. Huang +1
We investigate MeV-GeV -ray outbursts in 3C 273 in the frame of a time-dependent one-zone synchrotron self-Compton (SSC) model. In this model, electrons are accelerated to extra…
Modelling the multi-wavelength emission of flat spectrum radio quasar 3C 279
Y. G. Zheng, C. Y. Yang
We employ a length-dependent conical jet model for the jet structure and emission properties of flat spectrum radio quasar 3C 279 in the steady state. In the model, ultra-relativis…
Bethe-Heitler cascades as a plausible origin of hard spectra in distant TeV blazars
Y. G. Zheng, C. Y. Yang, S. J. Kang
Context. Very high-energy (VHE) -ray measurements of distant TeV blazars can be nicely explained by TeV spectra induced by ultra high-energy cosmic rays. Aims. We develop a mode…
