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.

The intrinsic shapes of dwarf irregular galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2013 Abstract We use the measured B-band axial ratios of galaxies from an updated catalogue of Local Volume galaxies to determine the intrinsic shape of dwarf irregular galaxies (de Vaucouleurs’ morphological types 8–10). We find that the shapes change systematically with luminosity, with fainter galaxies being thicker.

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.

GALACTIC WINDS IN IRREGULAR STARBURST GALAXIES [PDF]
, 2001 In this paper we present some results concerning the study of the development of galactic winds in blue compact galaxies. In particular, we model a situation very similar to that of the galaxy IZw18, the most metal poor and unevolved galaxy known locally.

The Astronomical Journal, 2023 The ongoing and forthcoming surveys will result in an unprecedented increase in the number of observed galaxies. As a result, data-driven techniques are now the primary methods for analyzing and interpreting this vast amount of information.

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.

The Astrophysical Journal Supplement Series, 2023 By applying our previously developed two-step scheme for galaxy morphology classification, we present a catalog of galaxy morphology for H -band-selected massive galaxies in the COSMOS-DASH field, which includes 17,292 galaxies with stellar mass M _ ...

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

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.
