Journal ArticleDOI
Thick gas discs in faint dwarf galaxies
TL;DR: In this article, the intrinsic axial ratio distribution of the gas discs of extremely faint MB < −14.5 dwarf irregular galaxies was determined based on the observed apparent axial ratios.
Journal ArticleDOI
New lessons from the H i size–mass relation of galaxies
Jing Wang,Bärbel S. Koribalski,Paolo Serra,Thijs van der Hulst,Sambit Roychowdhury,P. Kamphuis,P. Kamphuis,Jayaram N. Chengalur +7 more
TL;DR: In this paper, the authors revisited the H i size-mass relation of galaxies with a sample of more than 500 nearby galaxies covering over five orders of magnitude in H i mass and more than 10 B-band magnitudes.
Journal ArticleDOI
The spatially resolved Kennicutt–Schmidt relation in the H i-dominated regions of spiral and dwarf irregular galaxies
TL;DR: In this paper, the authors studied the relation between average star formation rate and average cold gas surface density in the Hi dominated ISM of nearby spiral and dwarf irregular galaxies and found that conversion of gas to stars is independent of metallicity in the HI dominated regions of star-forming galaxies.
Journal ArticleDOI
First measurement of H i 21 cm emission from a GRB host galaxy indicates a post-merger system
M. Arabsalmani,M. Arabsalmani,Sambit Roychowdhury,Martin Zwaan,Nissim Kanekar,Michał J. Michałowski +5 more
TL;DR: In this paper, the authors reported the detection and mapping of atomic hydrogen in HI 21cm emission from ESO 184-G82, the host galaxy of the gamma ray burst 980425.
Journal ArticleDOI
The relation between atomic gas and star formation rate densities in faint dwarf irregular galaxies
TL;DR: In this article, the authors used data for faint (M_B > -14.5) dwarf irregular galaxies drawn from the FIGGS survey to study the correlation between the atomic gas density (Sigma_gas,atomic) and star formation rate in the galaxies.
