Radiation Properties of GeV Narrow Line Seyfert 1 Galaxies

Jin Zhang, X. N. Sun, S. N. Zhang +1

The broadband SEDs of four gamma-ray NLS1s are compiled and explained with the leptonic model. It is found that their characteristics and fitting parameters of the observed SEDs ar…

A Comprehensive Study of Gamma-Ray Burst Optical Emission: II. Afterglow Onset and Late Re-Brightening Components

En-Wei Liang, Liang Li, He Gao +12

We continue our systematic statistical study of various components in gamma-ray burst (GRB) optical lightcurves. We decompose the early onset bump and the late re-brightening bump…

GRB 110721A: photosphere "death line" and the physical origin of the GRB "Band" function

Bing Zhang, Rui-Jing Lu, En-Wei Liang +1

The prompt emission spectra of gamma-ray bursts (GRBs) usually have a dominant component that is well described by a phenomenological "Band" function. The physical origin of this s…

Hyper-accreting black hole as GRB central engine. I: Baryon loading in GRB jets

Wei-Hua Lei, Bing Zhang, En-Wei Liang

A hyper-accreting stellar-mass black hole has been long speculated as the best candidate of central engine of gamma-ray bursts (GRBs). Recent rich observations of GRBs by space mis…

A Comprehensive Analysis of Fermi Gamma-ray Burst Data: III. Energy-Dependent T90 Distributions of GBM GRBs and Instrumental Selection Effect on Duration Classification

Ying Qin, En-Wei Liang, Yun-Feng Liang +8

The durations (T90) of 315 GRBs detected with Fermi/GBM (8-1000 keV) by 2011 September are calculated using the Bayesian Block method. We compare the T90 distributions between this…

Blazar Anti-Sequence of Spectral Variability for Individual TeV Blazars

Jin Zhang, Shuang-Nan Zhang, En-Wei Liang

We compile from literature the broadband SEDs of twelve TeV blazars observed simultaneously or quasi-simultaneously with Fermi/LAT and other instruments. Two SEDs are available for…
