TL;DR
The FIGGS survey uses the GMRT to study the neutral interstellar medium in faint, nearby dwarf irregular galaxies, aiming to improve understanding of their gas properties and galaxy evolution.
Contribution
This survey provides the first large, statistically robust dataset of neutral ISM properties in faint dwarf irregular galaxies using GMRT observations.
Findings
Characterization of neutral gas in faint dwarf irregulars
Statistically significant data on ISM properties
Foundation for future galaxy evolution studies
Abstract
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 science that we anticipate can be done with this data set.
