Radiation Mechanism and Jet Composition of Gamma-Ray Bursts and GeV-TeV selected Radio Loud Active Galactic Nuclei
Jin Zhang, En-Wei Liang, Xiao-Na Sun +3
Gamma-ray bursts (GRBs) and GeV-TeV selected radio loud Active Galactic Nuclei (AGNs) are compared based on our systematic modeling of the observed spectral energy distributions of…
Relativistic Jet Properties of GeV-TeV Blazars and Possible Implications for the Jet Formation, Composition, and Cavity Kinematics
Jin Zhang, Xiao-Na Sun, En-Wei Liang +3
We fit the spectral energy distributions (SEDs) of a GeV-TeV FSRQ sample with the leptonic model. Their gamma_min of the relativistic electron distributions, which significantly af…
Spectral Variation of NLS1 Galaxy PMN J0948+0022
X. N. Sun, Jin Zhang, Y. Lu +2
Four well-sampled spectral energy distributions (SEDs) of PMN J0948+0022 are fitted with the syn+SSC+EC model to derive the physical parameters of its jets and to investigate the s…
GRB 121027A: long-lasting, energetic X-ray flares and clues to radiation mechanism and progenitor star
Fang-kun Peng, You-Dong Hu, Shao-Qiang Xi +4
GRB 121027A is un-usual with its extremely long-lasting, energetic X-ray flares. The total energy release in X-ray flares is about one order of magnitude higher than prompt gamma-r…
Blazar Anti-Sequence of Spectral Variation within individual Blazars: Cases for Mrk 501 and 3C 279
Jin Zhang, Shuang-Nan Zhang, En-Wei Liang
The jet properties of Mrk 501 and 3C 279 are derived by fitting the broadband spectral energy distributions with the lepton models. The derived gamma_b (the break Lorenz factor of…
