Spectral and temporal analysis of the joint Swift/BAT-Fermi/GBM GRB sample
Francisco Virgili, Ying Qin, Bing Zhang +1
Using the gamma-ray bursts simultaneously detected by Swift/BAT and Fermi/GBM we performed a joint spectral and temporal analysis of the prompt emission data and confirm the rough…
Lorentz Factor-Isotropic Luminosity/Energy Correlations of GRBS and Their Interpretation
Jing Lv, Yuan-Chuan Zou, Wei-Hua Lei +5
The bulk Lorentz factor of the gamma-ray burst (GRB) ejecta (Gamma_0) is a key parameter to understand the GRB physics. Liang et al. have discovered a correlation between Gamma_0 a…
Radiation Mechanisms and Physical Properties of GeV-TeV BL Lac Objects
Jin Zhang, En-Wei Liang, Shuang-Nan Zhang +1
BL Lac objects are the best candidates to study the jet properties since their spectral energy distributions (SEDs) are less contaminated by the emission from the accretion disk an…
Radiation Mechanisms and Physical Properties of GeV-TeV BL Lac Objects
Jin Zhang, En-Wei Liang, Shuang-Nan Zhang +1
Broadband spectral energy distributions (SEDs) are complied from literature for 24 TeV BL Lac objects. Two SEDs, which are identified as low and high states with their flux densiti…
Observational constraints on the external shock prior emission hypothesis of GRBs
Tesla Birnbaum, Bing Zhang, Bin-Bin Zhang +1
An intriguing hypothesis, that there exists a decaying X-ray emission component before the GRB trigger, has been suggested in order to explain the shallow decay phase of the X-ray…
