The hardness-duration correlation in the two classes of gamma-ray bursts
Yi-Ping Qin, Guang-Zhong Xie, Sui-Jian Xue +2
The well-known hardness-duration correlation of gamma-ray bursts (GRBs) is investigated with the data of the 4B catalog. We find that, while the hardness ratio and the duration are…
Correlations between various hardness ratios of gamma-ray bursts
Yi-Ping Qin, Guang-Zhong Xie, Xue-Tang Zheng +1
We study correlations between various hardness ratios of gamma-ray bursts (GRBs) and investigate if there are any differences between the two classes of the objects in the distribu…
Evidence consistent with the cosmological interpretation of quasar redshifts
Yi-Ping Qin, Guang-Zhong Xie, Xue-Tang Zheng +1
In this letter, the old issue of whether redshifts of quasars are of cosmological origin is investigated. We make a plot of absorption redshifts versus emission redshifts for quasa…
