Fraction of the X-ray selected AGNs with optical emission lines in galaxy groups
Feng Li, Qirong Yuan, Weihao Bian +2
Compared with numerous X-ray dominant active galactic nuclei (AGNs) without emission-line signatures in their optical spectra, the X-ray selected AGNs with optical emission lines a…
Multicolor Photometry of the Merging Galaxy Cluster A2319: Dynamics and Star Formation Properties
Peng-Fei Yan, Qi-Rong Yuan, Li Zhang +1
Asymmetric X-ray emission and powerful cluster-scale radio halo indicate that A2319 is a merging cluster of galaxies. This paper presents our multicolor photometry for A2319 with 1…
Star formation properties of galaxy cluster A1767
Peng-Fei Yan, Feng Li, Qi-Rong Yuan
Abell 1767 is a dynamically relaxed, cD cluster of galaxies with a redshift of 0.0703. Among 250 spectroscopically confirmed member galaxies within a projected radius of 2.5r_{200}…
Merger Dynamics of the Pair of Galaxy Clusters -- A399 and A401
Qirong Yuan, Pengfei Yan, Yanbin Yang +1
Convincing evidence of a past interaction between two rich clusters A399 and A401 was recently found by the X-ray imaging observations. In this paper we examine the structure and d…
