Testing a new luminosity/redshift indicator for -ray bursts
Zhi-Bin Zhang, Guang-Zhong Xie
We have tested a relative spectral lag (RSL) method suggested earlier as a luminosity/redshift (or distance) estimator, using the generalized method by Schaefer & Collazzi. We find…
An analysis of the durations of Swift Gamma-Ray Bursts
Zhi-Bin Zhang, Chul-Sung Choi
We report the systematic analysis of the durations for Swift gamma-ray bursts (GRBs) and compare the results with those of pre-Swift data. For 95 GRBs with known redshift, we show…
Inferring the emission regions for different kinds of gamma-ray bursts
Zhibin Zhang, G. Z. Xie, J. G. Deng +1
Using a theoretical model describing pulse shapes, we have clarified the relations between the observed pulses and their corresponding timescales, such as the angular spreading tim…
Method of determining cosmological parameter ranges with samples of candles with an intrinsic distribution
Yi-Ping Qin, Bin-Bin Zhang, Yun-Ming Dong +8
In this paper, the effect of the intrinsic distribution of cosmological candles is investigated. We find that, in the case of a narrow distribution, the deviation of the observed m…
Characteristics of profiles of gamma-ray burst pulses associated with the Doppler effect of fireballs
Yi-Ping Qin, Zhi-Bin Zhang, Fu-Wen Zhang +1
In this paper, we derive in a much detail the formula of count rates, in terms of the integral of time, of gamma-ray bursts in the framework of fireballs, where the Doppler effect…
