Michael R. Corbin, William D. Vacca, John E. Hibbard +2
We present deep U, narrow-V, and I-band images of the ultracompact blue dwarf galaxy HS 0822+3542, obtained with the Advanced Camera for Surveys / High Resolution Channel of the Hu…
FORS spectroscopy of galaxies in the Hubble Deep Field South
Dimitra Rigopoulou, William D. Vacca, Stefano Berta +2
We present low resolution multi-object spectroscopy of an I-band magnitude limited (I_{AB} ~ 23--23.5) sample of galaxies located in an area centered on the Hubble Deep Field-South…
