HI Selected Galaxies in the Sloan Digital Sky Survey II: The Colors of Gas-Rich Galaxies

Autor: West, Andrew A., Garcia-Appadoo, Diego A., Dalcanton, Julianne J., Disney, Mike J., Rockosi, Constance R., Ivezic, Zeljko

Publikováno v: Astron.J.138:796,2009

We utilize color information for an HI-selected sample of 195 galaxies to explore the star formation histories and physical conditions that produce the observed colors. We show that the HI selection creates a significant offset towards bluer colors t

HI Selected Galaxies in the Sloan Digital Sky Survey I: Optical Data

Autor: West, Andrew A., Garcia-Appadoo, Diego A., Dalcanton, Julianne J., Disney, Mike J., Rockosi, Constance M., Ivezic, Zeljko, Bentz, Misty C., Brinkmann, J.

We present the optical data for 195 HI-selected galaxies that fall within both the Sloan Digital Sky Survey (SDSS) and the Parkes Equatorial Survey (ES). The photometric quantities have been independently recomputed for our sample using a new photome

We present HST/WFPC2 observations of the dwarf galaxy HIPASS J1321-31. This unusual galaxy lies in the direction of the Centaurus A group of galaxies, and has a color-magnitude diagram with a distinctive red plume of luminous stars. This feature coul
