In this paper, we present data from the Blind Ultra-Deep HI Environmental Survey (BUDHIES), which is a blind 21-cm HI spectral line imaging survey undertaken with the Westerbork...

We use high-resolution HI data from the Westerbork HI Survey of Spiral and Irregular Galaxies (WHISP) to study the HI and angular momentum properties of a sample of 114...

It is known that the GRB equivalent hydrogen column density (N_HX_) changes with redshift and that, typically, N_HX_ is greater than the GRB host neutral hydrogen column...

We present an analysis of morphological, kinematic, and spectral asymmetries in observations of atomic neutral hydrogen (HI) gas from the Local Volume HI Survey (LVHIS), the VLA...

We explore the environment of 252 HI-bearing ultra-diffuse galaxies (HUDs) from the 100 per cent ALFALFA survey catalogue in an attempt to constrain their formation mechanism....

We present an HI study of the galaxy group LGG 351 using Widefield ASKAP L-band Legacy All-sky Blind Survey (WALLABY) early science data observed with the Australian Square...

We present a catalogue of galaxies in the northern Zone of Avoidance (ZoA), extracted from the shallow version of the blind HI survey with the Effelsberg 100m radio telescope,...

Sub-damped Lyman {alpha} systems (subDLAs; HI column densities of 19.0<=logN(HI)<20.3) are rarely included in the cosmic HI census performed at redshifts z_abs_>=1.5,...

HI stacking has proven to be a highly effective tool to statistically analyse average HI properties for samples of galaxies which may or may not be directly detected. With the...

Spatially resolved HI studies of dwarf galaxies have provided a wealth of precision data. However these high-quality, resolved observations are only possible for handful of...

In this paper we measure the far-infrared (FIR) and radio flux densities of a sample of 82 local gas-rich galaxies, including 70 "dwarf" galaxies (M_*<10^9^M{sun}_), from the...

We present a study of the HI and optical properties of nearby (z<=0.1) Low Surface Brightness galaxies (LSBGs). We started with a literature sample of ~900 LSBGs and divided...

In this paper, we test if nearby blue spheroid (BSph) galaxies may become the progenitors of star-forming spiral galaxies or passively evolving elliptical galaxies. Our sample...

We present the first estimate of the Ly{alpha} luminosity function using blind spectroscopy from the Multi Unit Spectroscopic Explorer, MUSE, in the Hubble Deep Field-South....

We have selected a sample of 41 extremely isolated galaxies (EIGs) from the local Universe using both optical and HI Arecibo Legacy Fast ALFA survey redshifts. Narrow-band...

We have developed a parallel code called the VoIgt profile Parameter Estimation Routine (VIPER) for automatically fitting the HI Ly{alpha} forest seen in the spectra of...

We present the results from our survey of HI 21-cm absorption, using Giant Metrewave Radio Telescope, Very Large Array and Westerbork Radio Synthesis Telescope, in a sample of...

The star-forming reservoir in the distant Universe can be detected through HI 21-cm absorption arising from either cool gas associated with a radio source or from within a...

High-accuracy HI profiles and linewidths are presented for inclined ((b/a)^o^<0.5) spiral galaxies in the southern Zone of Avoidance (ZOA). These galaxies define a sample for...

We present the properties of the first 250 {mu}m blind sample of nearby galaxies (15<D<46Mpc) containing 42 objects from the Herschel Astrophysical Terahertz Large Area...
