FIGGS: Faint Irregular Galaxies GMRT Survey – overview, observations and first results
Monthly Notices of the Royal Astronomical Society, 2008 The Faint Irregular Galaxies GMRT Survey (FIGGS) is a Giant Metrewave Radio Telescope (GMRT) based HI imaging survey of a systematically selected sample of extremely faint nearby dwarf irregular galaxies.

Chemical evolution of dwarf irregular and blue compact galaxies
Astronomy and Astrophysics, 2011 Aims: Dwarf irregular and blue compact galaxies are very interesting objects since they are relatively simple and unevolved. We aim at deriving the formation and chemical evolution history of late-type dwarf galaxies and at comparing it with DLA systems.

Star Formation in Irregular Galaxies
Science, 1989Irregular 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, 1978The 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.

Periodic bursts of star formation in irregular galaxies [PDF]
Astronomy and Astrophysics, 2004 We present N-body/SPH simulations of the evolution of an isolated dwarf galaxy including a detailed model for the ISM, star formation and stellar feedback. Depending on the strength of the feedback, the modelled dwarf galaxy shows periodic or quasi-periodic bursts of star formation of moderate strength.

Starbursts in Ring and Irregular Galaxies
Publications of the Astronomical Society of Australia, 1991AbstractThis 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 ...
