In this paper, we report the peculiar HI morphology of the cluster spiral galaxy NGC 6145, which has a 150 kpc HI filament on one side that is nearly parallel to its major axis. This filament is made up of several HI clouds and the diffuse HI gas between them, with no optical counterparts. We compare its HI distribution with other one-sided HI distributions in the literature, and find that the overall HI distribution is very different from the typical tidal and ram-pressure stripped HI shape…

The Cold Gaseous Halo of NGC 891
We present H I observations of the edge-on galaxy NGC 891. These are among the deepest ever performed on an external galaxy. They reveal a huge gaseous halo, much more extended than seen previously
VLA H I Observations of Gas Stripping in the Virgo Cluster Spiral NGC 4522
We present VLA H I observations at ~20'' 1.5 kpc resolution of the highly inclined, H I–deficient Virgo Cluster spiral galaxy NGC 4522, which is one of the clearest and nearest cases of ongoing
Deep H I Survey of the Spiral Galaxy NGC 2403
Published in: Astron. J. 123 (2002) 3124-3140 citations recorded in [Science Citation Index] Abstract: High sensitivity H I observations of the nearby spiral galaxy NGC 2403 obtained with the VLA are
The `shook up' galaxy NGC 3079: The complex interplay between H I, activity and environment
We present deep neutral hydrogen (H I) observations of the starburst/Seyfert galaxy NGC 3079 and its environment, obtained with the Westerbork Synthesis Radio Telescope. Our observations reveal
A 180 Kiloparsec Tidal Tail in the Luminous Infrared Merger Arp 299
We present VLA H I observations and University of Hawaii 88 inch (2.2 m) deep optical B- and R-band observations of the IR-luminous merger Arp 299 (= NGC 3690 + IC 694). These data reveal a gas-rich
The Interacting Galaxies NGC 5394/5395: A Post-Ocular Galaxy and Its Ring/Spiral Companion
H I, radio continuum, Fabry-Perot Hα, and 12CO J = 1 → 0 observations and broadband optical and near infrared images are presented of the interacting spiral galaxies NGC 5395 and NGC 5394.
The Westerbork HI survey of spiral and irregular galaxies - I. HI imaging of late-type dwarf galaxies
Neutral hydrogen observations with the Westerbork Synthesis Radio Telescope are presented for a sample of 73 late-type dwarf galaxies. These observations are part of the WHISP project (Westerbork Hi
As part of several H I synthesis-mapping studies of merging galaxies, we have mapped the tidal gas in the three disk-disk merger systems Arp 157 (NGC 520), Arp 220, and Arp 299 (NGC 3690). These
High-Resolution H I Mapping of NGC 4038/39 (“The Antennae”) and Its Tidal Dwarf Galaxy Candidates
We present new VLA C + D array H I observations and optical and near-infrared imaging of the well-known interacting system NGC 4038/39, "The Antennae." At low spatial resolution (similar to 40"), the
Collisional removal of H I from the inner disks of Virgo Cluster galaxies
There is sufficient observational evidence to show that many Virgo Cluster spirals are H I deficient in their inner disks (in addition to being H I deficient globally, as previously established). It
