A test of the power law relationship between gamma-ray burst pulse width ratio and energy expected in fireballs or uniform jets
Z. -Y. Peng, Y. -P. Qin, B. -B. Zhang +3
Recently, under the assumption that the Doppler effect of the relativistically expanding fireball surface is important, Qin et al. showed that in most cases the power law relations…
The FWHM of local pulses and the corresponding power-law index of gamma-ray burst FRED pulses
L. -W. Jia, Y. -P. Qin
The FWHM of gamma-ray burst (GRB) pulses is known to be related with energy by a power-law. We wonder if the power-law index is related with the corresponding local pulse width…
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…
Relationship between the gamma-ray burst pulse width and energy due to the Doppler effect of fireballs
Y. -P. Qin, Y. -M. Dong, R. -J. Lu +2
We study in details how the pulse width of gamma-ray bursts is related with energy under the assumption that the sources concerned are in the stage of fireballs. Due to the Doppler…
