  • Velocities of RFGC galaxies

    A list of radial velocities, HI line widths and peculiar velocities of 1327 galaxies from the RFGC catalogue has been compiled using actual observations and literature data. The...
  • Star formation in isolated galaxies

    We use the FUV fluxes measured with the GALEX to study the star formation properties of galaxies collected in the Local Orphan Galaxies catalog (LOG, 2011AstBu..66....1K). Among...
  • Neutral hydrogen evolution over the past 11Gyr

    We present the results of a blind search for intervening HI 21cm absorption towards 260 radio sources in the redshift range 0<z<2.74 with the Green Bank Telescope. The...
  • Radio tails of galaxies in the Coma cluster

    Previous studies have revealed a population of galaxies in galaxy clusters with ram pressure stripped (RPS) tails of gas and embedded young stars. We observed 1.4GHz continuum...
  • Abell 963 and Abell 2192 HI data

    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...
  • HI angular momentum on late-type galaxies

    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...
  • GRB hydrogen column densities

    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...
  • Group galaxies in ALFALFA survey

    We estimate the HI mass function (HIMF) of galaxies in groups based on thousands of ALFALFA (Arecibo Legacy Fast ALFA survey) HI detections within the galaxy groups of four...
  • HI asymmetries with LVHIS, VIVA, and HALOGAS

    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...
  • HI-bearing ultra-diffuse ALFALFA galaxies

    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....
  • ASKAP HI imaging of the Lyon Group of Galaxies 351

    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...
  • The EZOA survey

    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 Ly{alpha} systems in XQ-100 survey

    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,...
  • HISS HI stacking tool applied to NIBLES spectra

    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...
  • Star formation on LV dwarf galaxies

    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...
  • LVHIS. far-infrared radio correlation

    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...
  • SDSS post-merger galaxies HI data

    We present a detailed assessment of the global atomic hydrogen gas fraction (f_gas_=log[M_HI_/M) in a sample of post-merger galaxies identified in the Sloan Digital Sky Survey...
  • Local Volume H I Survey (LVHIS)

    The 'Local Volume HI Survey' (LVHIS) comprises deep HI spectral line and 20-cm radio continuum observations of 82 nearby, gas-rich galaxies, supplemented by multiwavelength...
  • xGASS catalog

    We present the extended GALEX Arecibo SDSS Survey (xGASS), a gas fraction-limited census of the atomic hydrogen (HI) gas content of 1179 galaxies selected only by stellar mass...
  • LSBG HI and optical properties

    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...
