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…
Why are some galaxy disks extremely thin?
Arunima Banerjee, Chanda J. Jog
Some low surface brightness galaxies are known to have extremely thin stellar disks with the vertical to planar axes ratio 0.1 or less, often referred to as superthin disks. Althou…
Theoretical determination of HI vertical scale heights in the dwarf galaxies: DDO 154, HoII, IC2574 & NGC2366
Arunima Banerjee, Chanda J. Jog, Elias Brinks +1
In this paper, we model dwarf galaxies as a two-component system of gravitationally coupled stars and atomic hydrogen gas in the external force field of a pseudo-isothermal dark ma…
Dark matter dominance at all radii in the superthin galaxy UGC 7321
Arunima Banerjee, Lynn D. Matthews, Chanda J. Jog
We model the shape and density profile of the dark matter halo of the low surface brightness, superthin galaxy UGC 7321, using the observed rotation curve and the HI scale height d…
