Distinguishing RBL-like objects and XBL-like objects with the peak emission frequency of the overall energy spectrum
Yi-Ping Qin, G. Z. Xie, Xue-Tang Zheng
We investigate quantitatively how the peak emission frequency of the overall energy spectrum is at work in distinguishing RBL-like and XBL-like objects. We employ the sample of Gio…

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…
