Cold HI in faint dwarf galaxies
Narendra Nath Patra, Jayaram N. Chengalur, Igor D. Karachentsev +2
We present the results of a study of the amount and distribution of cold atomic gas, as well its correlation with recent star formation in a sample of extremely faint dwarf irregul…
Andromeda IV, a solitary gas-rich dwarf galaxy
I. D. Karachentsev, Jayaram. N. Chengalur, R. B. Tully +4
Observations are presented of the isolated dwarf irregular galaxy And IV made with the Hubble Space Telescope Advanced Camera for Surveys and the Giant Metrewave Radio Telescope in…
Modeling HI distribution and kinematics in the edge-on dwarf irregular galaxy KK250
Narendra Nath Patra, Arunima Banerjee, Jayaram N. Chengalur +1
We model the observed vertical distribution of the neutral hydrogen (HI) in the faint (M_B ~ -13.7 mag) edge-on dwarf irregular galaxy KK250. Our model assumes that the galaxy cons…
Characterizing the Turbulent Properties of the Starless Molecular Cloud MBM16
Nickolas M. Pingel, Snezana Stanimirovic, J. E. G. Peek +13
We investigate turbulent properties of the non-star-forming, translucent molecular cloud, MBM16 by applying the statistical technique of a two-dimensional spatial power spectrum (S…
A slow bar in the dwarf irregular galaxy NGC 3741
Arunima Banerjee, Narendra Nath Patra, Jayaram N. Chengalur +1
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 {H\,{\sc i}} disk which extend…
The HI column density distribution function in faint dwarf galaxies
Narendra Nath Patra, Jayaram N. Chengalur, Ayesha Begum
We present the HI column density distribution function,\fnh, as measured from dwarf galaxies observed as part of the Faint Irregular Galaxy GMRT (FIGGS) survey. We find that the sh…
