The oxygen abundance deficiency in irregular galaxies [PDF]
, 2000 The observed oxygen abundances in a number of irregular galaxies have been compared with predictions of the closed-box model of chemical and photometric evolution of galaxies. Oxygen is found to be deficient with respect to the predicted abundances. This

TRANSFORMATION OF A VIRGO CLUSTER DWARF IRREGULAR GALAXY BY RAM PRESSURE STRIPPING: IC3418 AND ITS FIREBALLS [PDF]
, 2013 We present optical imaging and spectroscopy and H i imaging of the Virgo Cluster galaxy IC 3418, which is likely a “smoking gun” example of the transformation of a dwarf irregular into a dwarf elliptical galaxy by ram pressure stripping.

EVIDENCE FOR AN INTERACTION IN THE NEAREST STARBURSTING DWARF IRREGULAR GALAXY IC 10 [PDF]
, 2013 Using deep 21 cm H i data from the Green Bank Telescope we have detected an ≳18.3 kpc long gaseous extension associated with the starbursting dwarf galaxy IC 10.

A slow bar in the dwarf irregular galaxy NGC 3741 [PDF]
, 2013 Using the Tremaine-Weinberg method, we measure the speed of the HI bar seen in the disk of NGC 3741. NGC 3741 is an extremely gas rich galaxy with an Hi disk which extends to about 8.3 times its Holmberg radius.

THE STELLAR AND GAS KINEMATICS OF THE LITTLE THINGS DWARF IRREGULAR GALAXY NGC 1569 [PDF]
, 2012 In order to understand the formation and evolution of Magellanic-type dwarf irregular (dIm) galaxies, one needs to understand their three-dimensional structure.

On the massive star content of the nearby dwarf irregular Wolf-Rayet galaxy IC 4662 [PDF]
, 2009 Aims. We investigate the massive stellar content of the nearby dwarf irregular Wolf-Rayet galaxy IC 4662, and consider its global star forming properties in the context of other metal-poor galaxies, the SMC, IC 10 and NGC 1569. Methods.

Distance and reddening of the Local Group dwarf irregular galaxy NGC 6822 [PDF]
, 2012 On the basis of a new photometric analysis of the Local Group dwarf irregular galaxy NCG 6822 based on observations obtained with the Advanced Camera for Surveys onboard the Hubble Space Telescope, we have obtained a new estimate of the extinction of two

THE CLUSTER POPULATION OF THE IRREGULAR GALAXY NGC 4449 AS SEEN BY THE HUBBLE ADVANCED CAMERA FOR SURVEYS [PDF]
, 2011 We present a study of the star cluster population in the starburst irregular galaxy NGC 4449 based on B, V, I, and Hα images taken with the Advanced Camera for Surveys on the Hubble Space Telescope. We derive cluster properties such as size, ellipticity,
