Radiative Efficiency of Disk Accretion in Individual SDSS QSOs
Shumei Wu, Youjun Lu, Fupeng Zhang +1
We estimate the radiative efficiency (epsilon) of individual type 1 SDSS QSOs by using their bolometric luminosities (L_{bol}) and accretion rates (\dot{M}_{\bullet,acc}), which ma…
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…
A Comptonization Model for the Prompt Optical and Infrared Emission of GRB 041219A
Zheng Zheng, Ye Lu, Yong-Heng Zhao
Prompt optical emission from the -ray burst of GRB 041219A has been reported by Vestrand et al. There was a fast rise of optical emission simultaneous with the dominant -ray…
A Possible Energy Mechanism for Cosmological Gamma-ray Bursts
K. S. Cheng, Y. Lu
We suggest that an extreme Kerr black hole with a mass , a dimensionless angular momentum and a marginal stable orbital radius $r_{ms}\sim 3r_s\sim 10^{…
