HI environment
HI-rich galaxies have more HI in the 500 kpc envrionment which is outside individually detected sources but cumulates to significant mass.. (Wang et al.2015MNRAS)
HI in satellites
HI-rich galaxies have HI-rich satellites within a distance of 1 Mpc around them.. (E.Wang et al.2015MNRAS)
Radial HI distribution
Different kind of galaxies have surprisingly similar outer HI disk after a very simple scaling... (Wang et al.2014MNRAS)
HI morphology
The extremely HI-rich galaxies have only normal HI morpholgies.. (Wang et al.2013MNRAS)
The stellar halo
The radial and azimuthal distributions of optical light in the region dominated by stellar halos depend on both the stellar mass and concentration of the galaxies (D'Souza et al.2014)
Bars and central SF
Galaxies hosting bars tend to have significant enhanced central star formation but also tend to have suppressed central star formation.. (Wang et al.2012MNRAS)
Outer disk and HI gas
Stellar population in galactic outer disks are only determined by HI gas content.. (Wang et al.2011MNRAS)
BGCs
Brightest cluster galaxies are on average old and dead, despite the cooling flow of gas in some really massive clusters.. (Wang et al.2010MNRAS)
