The mass dependence of structure, star formation rate, and mass assembly mode at 0.5<z< 2.5
Yizhou Gu, Guanwen Fang, Qirong Yuan +5
To investigate the mass dependence of structural transformation and star formation quenching, we construct three galaxy samples using massive () red, green…
Effect of richness on AGN and star formation activities in SDSS galaxy groups
Feng Li, Yi-Zhou Gu, Qi-Rong Yuan +3
Based on a large sample of 254 220 galaxies in 81 089 groups, which are selected from the spectroscopic galaxy sample of the SDSS DR12, we investigate the radial distribution of in…
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…
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}…
Multicolor Photometry of the Galaxies in Abell 1775: Substructures, Luminosity Functions, and Star-Formation Properties
Li Zhang, Qirong Yuan, Qian Yang +4
An optical photometric observation in 15 bands was carried out for nearby galaxy cluster Abell 1775 by the Beijing-Arizona-Taiwan-Connecticut (BATC) multi-color system. Over 5000 s…
