Low-Luminosity Gamma-Ray Bursts as a Distinct GRB Population:A Firmer Case from Multiple Criteria Constraints
Francisco Virgili, Enwei Liang, Bing Zhang
The intriguing observations of Swift/BAT X-ray flash XRF 060218 and the BATSE-BeppoSAX gamma-ray burst GRB 980425, both with much lower luminosity and redshift compared to other ob…
GRB Radiative Efficiencies Derived from the Swift Data: GRBs vs. XRFs, Long vs. Short
Bing Zhang, Enwei Liang, Kim L. Page +17
We systematically analyze the prompt emission and the early afterglow data of a sample of 31 GRBs detected by {\em Swift} before September 2005, and estimate the GRB radiative effi…
On the Spectral Lags of the Short Gamma-Ray Bursts
Tingfeng Yi, Enwei Liang, Yiping Qin +1
We present a detail analysis on the spectral lags of the short gamma-ray bursts (GRBs) and compare them with that of the long GRBs by using the CGRO/BATSE GRB Catalog. Our results…
Very Early Optical Afterglows of Gamma-Ray Bursts: Evidence for Relative Paucity of Detection
P. W. A. Roming, P. Schady, D. B. Fox +38
Very early observations with the Swift satellite of gamma-ray burst (GRB) afterglows reveal that the optical component is not detected in a large number of cases. This is in contra…
Identification of Two categories of optically bright gamma-ray bursts
Enwei Liang, Bing Zhang
We present the results of a systematical analysis of the intrinsic optical afterglow light curves for a complete sample of gamma-ray bursts (GRBs) observed in the period from Feb.…
Testing the Universal Structured Jet Models of Gamma-Ray Bursts by BATSE Observations
X. H. Cui, E. W. Liang, R. J. Lu
Assuming that the observed gamma-ray burst (GRB) rate as a function of redshift is proportional to a corrected star formation rate, we derive the empirical distribution of the view…
