We present neutral hydrogen (H{\sc i}) observations with the Giant Metrewave Radio Telescope ({\it GMRT}) of the interacting galaxies NGC5996 and NGC5994, which make up the Arp72 system. Arp72 is an M51-type system and shows a complex distribution of H{\sc i} tails and a bridge due to tidal interactions. H{\sc i} column densities ranging from 0.8$-1.8\times10^{20}$ atoms cm$^{-2}$ in the eastern tidal tail to 1.7$-2\times10^{21}$ atoms cm$^{-2}$ in the bridge connecting the two galaxies, are…

Dark matter and H i in ultra-diffuse galaxy UGC 2162

Our GMRT (Giant Metrewave Radio Telescope) H i observations of the ultra-diffuse galaxy (UDG) UGC 2162, projected ∼ 300 kpc from the centre of the M 77 group, reveal it to a have an extended H i

Arp 65 interaction debris: massive H I displacement and star formation

Context. Pre‐merger tidal interactions between pairs of galaxies are known to induce significant changes in the morphologies and kinematics of the stellar and interstellar medium components. Large


Using archival data from ATCA, WHISP, and the Very Large Array, we have analyzed the H i emission of 22 tidal tail regions of the Mullan et al. sample of pairwise interacting galaxies. We have

The Origin of Faint Tidal Features around Galaxies in the RESOLVE Survey

We study tidal features around galaxies in the REsolved Spectroscopy Of a Local VolumE (RESOLVE) survey. Our sample consists of 1048 RESOLVE galaxies that overlap with the DECam Legacy Survey, which



H i content and star formation in the interacting galaxy Arp86

We present the results of Giant Metrewave Radio Telescope (GMRT) observations of the interacting system Arp86 in both neutral atomic hydrogen, H I, and in radio continuum at 240 606 and 1394 MHz. In

The Parkes HI survey of the Magellanic System

We present the first fully and uniformly sampled, spatially complete $\ion{H}{i}$ survey of the entire Magellanic System with high velocity resolution ($\Delta v = 1.0$ km s -1 ), performed with the


This paper presents new VLA observations in the 21 cm H I line of the Sc spiral galaxy M51 (NGC 5194) at resolutions ranging from 5 arcsec to 34 arcsec. The H I in the inner regions follows the

Star Formation in M51 Triggered by Galaxy Interaction

We have mapped the inner 360'' regions of M51 in the 158 μm [C II] line at 55'' spatial resolution using the far-infrared imaging Fabry-Perot interferometer (FIFI) on the Kuiper Airborne Observatory

Intergalactic H II Regions Discovered in SINGG

A number of very small isolated H II regions have been discovered at projected distances up to 30 kpc from their nearest galaxy. These H II regions appear as tiny emission-line objects in narrowband
