Star Formation in Irregular Galaxies

Science, 1989
Irregular galaxies can be viewed as laboratories for studying the processes of star formation. This class of galaxy, unlike the more familiar spiral galaxies, forms stars without spiral arms and does so from a chemically less-evolved interstellar medium.

The Kinematics of Spiral and Irregular Galaxies

Annual Review of Astronomy and Astrophysics, 1978
The present status of kinematical studies of intermediate- and late-type galaxies is reviewed. The emphasis is on observations that result in extensive maps of velocity fields rather than determinations of rotation curves from major axis observations only.

Starbursts in Ring and Irregular Galaxies

Publications of the Astronomical Society of Australia, 1991
AbstractThis paper presents the current status of a Ph.D. project undertaken to search for extended-scale bursts of star formation (> 1 kpc) in irregular and collisionally produced ring galaxies, principally in the southern half of the sky. Results of recent 8.4 GHz radio continuum observations and UBVRI CCD imaging of some of the program galaxies ...

Dwarf Irregular Galaxies

2004
Dwarf irregular galaxies at optical wavelengths are small, faint and appear to be unstructured and irregular in shape. They are typically gas-rich, metal-poor systems, with varying levels of STAR FORMATION occurring in a haphazard manner across the ...
