The color picture shown here is of Sextans A = DDO 75, a tiny irregular galaxy.
This combination of
UBV images was made by Howard Bond
for the cover of PASP
from images taken by D. Hunter at the 0.9 m at CTIO.
See 1997, PASP, 109, 937 for a review of star formation in irregulars.

A Survey of Dwarf Galaxies
Over the past 15 years, we have conducted a multi-wavelength survey of a large sample of
galaxies without spiral arms for the purposes of understanding how tiny galaxies form
stars. The sample includes 94 dwarf irregular (dIm), 24 Blue Compact Dwarfs (BCD),
and 18 Sm galaxies.
The data are available:
color maps (one filter image divided by
surface brightness plots.
Halpha images are available via NED.

We have put the UBV images together into
color pictures of a selected sub-sample of galaxies.
