Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) broad-band imaging and GBT HI line observations of 11 nearby (z<0.03) Ultra-compact (diameter less than 1 kpc) Blue Dwarf Galaxies (UCBDs). Results from HST cycle13 program GO-10180 and GBT program GBT05A-034.

Note: All data on Pox 186 was taken by Michael Corbin (ASU) & William Vacca (SOFIA) prior to the above two programs. It was the main motivation for the work reported on here.
