Dark Matter and the Chemical Evolution of Irregular Galaxies [PDF]
, 1998 We present three types of chemical evolution models for irregular galaxies: closed-box with continuous star formation rates (SFRs), closed-box with bursting SFRs, and O-rich outflow with continuous SFRs. We discuss the chemical evolution of the irregular

Disk Galaxies Are Self-similar: The Universality of the H i-to-Halo Mass Ratio for Isolated Disks
The Astrophysical Journal Letters, 2023 Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter.

Pavo: Discovery of a Star-forming Dwarf Galaxy Just Outside the Local Group
The Astrophysical Journal Letters, 2023 We report the discovery of Pavo, a faint ( M _V = −10.0), star-forming, irregular, and extremely isolated dwarf galaxy at D ≈ 2 Mpc. Pavo was identified in Dark Energy Camera Legacy Survey imaging via a novel approach that combines low surface brightness

The History of Galaxies and Galaxy Number Counts [PDF]
, 1997 (Abridged) A simple quantitative model is presented for the history of galaxies to explain galaxy number counts, redshift distributions and some other related observations. We first infer that irregular galaxies and the disks of spiral galaxies are young,

FIGGS Faint Irregular Galaxies GMRT Survey [PDF]
, 2008 The Faint Irregular Galaxies GMRT Survey (FIGGS) is a large program aimed at providing a comprehensive and statistically robust characterisation of the neutral ISM properties of faint (M_B > -14.5), nearby, gas rich, dwarf irregular galaxies using the Giant Metrewave Radio Telescope (GMRT). Here we briefly describe the survey and discuss some of the

THE CRITERIA FOR MORPHOLOGICAL CLASSIFICATION OF PF GALAXY CLUSTERS
Odessa Astronomical Publications, 2013 The morphological types of galaxy clusters resulting from their out ward appearance is physically related to the clusters and their member galaxies. Presented here is an adopted system of morphological types of galaxy clusters based on the Zwicky, Boutz ...

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 extended structure of the dwarf irregular galaxy Sagittarius [PDF]
, 2014 We present a detailed study of the stellar and HI structure of the dwarf irregular galaxy Sagittarius. We use new deep and wide field photometry to trace the surface brightness profile of the galaxy out to ~5.0' (corresponding to ~1600 pc) and down to ...
