Environmental Effects on Galaxy Evolution Based on the Sloan Digital Sky Surveyrelation, we have found two characteristic environments where galaxy morphologies change dramatically, indicating there exist two different physical mechanisms responsible for the cluster galaxy evolution. We also found an unusual population of galaxies, which have spiral morphology but do not have

The Low-luminosity Galaxy Population in the NGC 5044 Groupong objects originally classified as early-type dwarfs. Particularly, a significant fraction of bright dwarf “ellipticals” show a distinct bulge+disc structure; we thus re-classify these objects as dwarf lenticulars (dS0).

We measured radial velocities for 87 LMC RR Lyrae, and metallicities for 78 RR Lyrae, nearly tripling the previous sample. These targets are located in 11 fields covering a wide range of
