Dynamic changes of emitting electron distribution in the jet of 3C 279: signatures of acceleration and cooling
Dahai Yan, Jianjian He, Jinyuan Liao +2
We study the dynamic changes of electron energy distribution (EED) through systematically analysing the quasi-simultaneous spectral energy distributions (SEDs) of the flat spectrum…
Formation of very hard electron and gamma-ray spectra of flat spectrum radio quasar in fast-cooling regime
Dahai Yan, Li Zhang, Shuang-Nan Zhang
In external Compton scenario, we investigate the formation of the very hard electron spectrum in the fast-cooling regime, using a time-dependent emission model. It is shown that a…
Parameter constraints in a near-equipartition model with multi-frequency \emph{NuSTAR}, \emph{Swift} and \emph{Fermi-LAT} data from 3C 279
Dahai Yan, Li Zhang, Shuang-Nan Zhang
Precise spectra of 3C 279 in the 0.5-70 keV range, obtained during two epochs of \emph{Swift} and \emph{NuSTAR} observations, are analyzed using a near-equipartition model. We appl…
Near-Equipartition Jets with Log-Parabola Electron Energy Distribution and the Blazar Spectral-Index Diagrams
Charles D. Dermer, Dahai Yan, Li Zhang +2
Fermi-LAT analyses show that the gamma-ray photon spectral indices Gamma_gamma of a large sample of blazars correlate with the vFv peak synchrotron frequency v_s according to the r…
