Chemical evolution of irregular galaxies [PDF]
arXiv, 1998 The state-of-the-art of chemical evolution models for Irregular and Blue Compact galaxies is reviewed. The resulting scenarios for the initial mass function, the regime of star formation and the efficiency of gas outflows are described: The IMF appears to be roughly the same everywhere; the SF has possibly followed a bursting regime in BCGs and a more ...

A High-Resolution Study of the HI Content of Local Group Dwarf Irregular Galaxy WLM [PDF]
, 2007 Dwarf irregular galaxies are unique laboratories for studying the interaction between stars and the interstellar medium in low mass environments. We present the highest spatial resolution observations to date of the neutral hydrogen content of the Local ...

The star formation history of the Sculptor Dwarf Irregular Galaxy [PDF]
, 2012 [abridged] We study the resolved stellar populations and derive the SFH of the SDIG, a gas-rich dwarf galaxy member of the NGC7793 subgroup in the Sculptor group. We construct a CMD using archival HST observations and examine its stellar content.

Genuine Irregular Galaxies as a Relic of Building Blocks of Galaxies [PDF]
arXiv, 2013 In order to understand nature of building blocks of galaxies in the early universe, we investigate "genuine irregular galaxies (GIGs)" in the nearby universe. Here, GIGs are defined as isolated galaxies without regular structures (spheroid, bulge, disk, bar, spiral arm, and nucleus). Using the results of two excellent studies on galaxy morphology based

FIGGS: Faint Irregular Galaxies GMRT Survey [PDF]
, 2007 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).

Developing and adult reef fish show rapid light‐induced plasticity in their visual system
Molecular Ecology, Volume 32, Issue 1, Page 167-181, January 2023., 2023 Abstract The visual capabilities of fish are optimized for their ecology and light environment over evolutionary time. Similarly, fish vision can adapt to regular changes in light conditions within their lifetime, e.g., ontogenetic or seasonal variation.

UVIT Imaging of WLM: Demographics of Star-forming Regions in the Nearby Dwarf Irregular Galaxy [PDF]
Astronomical Journal, 2018 We present a study of star-forming regions and their demographics in the nearby dwarf irregular galaxy WLM using Ultraviolet Imaging Telescope (UVIT) multiband observations in three filters, F148W, N245M, and N263M.
