MaNGA integral-field stellar kinematics of LoTSS radio galaxies: Luminous radio galaxies tend to be slow rotators
Xuechen Zheng, Huub Röttgering, Arjen van der Wel +1
The radio jets of an active galactic nucleus (AGN) can heat up the gas around a host galaxy and quench star formation activity. The presence of a radio jet could be related to the…
Link between radio-loud AGNs and host-galaxy shape
X. C. Zheng, H. J. A. Röttgering, P. N. Best +7
The morphology of quiescent galaxies has been found to be correlated with the activity of their central super massive black hole. In this work, we use data from the first data rele…
Piercing through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields. II. Are Highly Obscured AGNs the Missing Link in the Merger-Triggered AGN-Galaxy Coevolution Models?
Junyao Li, Yongquan Xue, Mouyuan Sun +12
By using a large highly obscured () AGN sample (294 sources at ) selected from detailed X-ray spectral analyses in the deepest Chandra…
Piercing Through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields: I. X-ray Spectral and Long-term Variability Analyses
Junyao Li, Yongquan Xue, Mouyuan Sun +13
We present a detailed X-ray spectral analysis of 1152 AGNs selected in the Chandra Deep Fields (CDFs), in order to identify highly obscured AGNs (…
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…
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…
