  • Arecibo Dual-Beam Survey

    The Arecibo Dual-Beam Survey is a "blind" 21 cm search for galaxies covering ~430deg^2^ of sky. We present the data from the detection survey as well as from the follow-up...
  • Deep survey of HI-selected galaxies

    In a 21cm neutral hydrogen survey of approximately 55{deg}^2^ out to a redshift of cz=8340km/s, we have identified 75 extragalactic HI sources. These objects comprise a...
  • Galactic H I column densities

    We have determined accurate values of the Galactic neutral hydrogen column density, N_H_, toward 220 quasars and active galactic nuclei from 21cm H I measurements made on the...
  • PANDISC. I. HI model applied to ALFAFA & SPARC gal.

    Modeling the integrated HI spectra of galaxies has been a difficult task, due to their diverse shapes, but more dynamical information is waiting to be explored in HI line...
  • WALLABY pilot survey: HI gas in Hydra cluster

    This study uses HI image data from the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) pilot survey with the Australian Square Kilometre Array Pathfinder (ASKAP)...
  • Gas content of the dwarf gal. within 2Mpc of the MW

    The gas content of the complete compilation of Local Group dwarf galaxies (119 within 2Mpc) is presented using HI survey data. Within the virial radius of the Milky Way (224kpc...
  • FUSE survey of H_2_ in the Galactic disk

    We report results from a Far Ultraviolet Spectrographic Explorer (FUSE) survey of interstellar molecular hydrogen (H_2_) in the Galactic disk toward 139 O-type and early B-type...
  • HST obs. of MADCASH-1 and MADCASH-2

    We present a deep Hubble Space Telescope (HST) imaging study of two dwarf galaxies in the halos of Local Volume Large Magellanic Cloud (LMC) analogs. These dwarfs were...
  • SDSS-IV/MaNGA ; galaxy stellar and HI masses

    Gaseous inflows are necessary suppliers of galaxies star-forming fuel, but are difficult to characterize at the survey scale. We use integral-field spectroscopic measurements of...
  • GBT HI obs. of ultradiffuse galaxies

    We present neutral hydrogen (HI) observations using the Robert C. Byrd Green Bank Telescope (GBT) of 70 optically detected UDG candidates in the Coma region from the...
  • Cosmicflows-4: Tully-Fisher distances

    We present the distances of 9792 spiral galaxies lying within 15000km/s using the relation between luminosity and rotation rate of spiral galaxies. The sample is dominantly, but...
  • Parameters for the 58 {tau}HI(v) sightlines

    Resolving the phase structure of neutral hydrogen (HI) is crucial for understanding the life cycle of the interstellar medium (ISM). However, accurate measurements of HI...
  • Cosmicflows-4: Tully-Fisher relation calibrations

    This study is a part of the Cosmicflows-4 project with the aim of measuring the distances of more than ~10000 spiral galaxies in the local universe up to ~15000km/s. New HI line...
  • COS CGM compendium (CCC). III. z<=1 Ly{alpha} syst.

    We characterize the metallicities and physical properties of cool, photoionized gas in a sample of 152 z<=1 strong Ly{alpha} forest systems (SLFSs, absorbers with...
  • OB stars embedded in the HI gas of SMC

    We investigate the kinematics of neutral gas in the Small Magellanic Cloud (SMC) and test the hypothesis that it is rotating in a disk. To trace the 3D motions of the neutral...
  • SDSS, WISE and HI data of local spiral galaxies

    The emerging light from a galaxy is under the influence of its own interstellar medium, as well as its spatial orientation. Considering a sample of 2239 local spiral galaxies in...
  • GALFA-HI search for local dwarf galaxies

    In recent years, ultrafaint dwarf (UFD) galaxies have been found through systematic searches of large optical surveys. However, the existence of Leo T, a nearby gas-rich dwarf,...
  • The COS CGM Compendium (CCC). II. Lyman limit syst.

    We present the results from our COS circumgalactic medium (CGM) compendium (CCC), a survey of the CGM at z<~1 using HI-selected absorbers with 15<logN_HI_<19. We focus...
  • The COS CGM compendium. I. Initial results

    We present a neutral hydrogen-selected absorption-line survey of gas with HI column densities 15<logN_HI_<19 at z<~1 using the Cosmic Origins Spectrograph on the Hubble...
  • The HIPASS Catalog (HICAT) + WISE galaxies

    We have measured the relationships between HI mass, stellar mass, and star formation rate using the HI Parkes All-Sky Survey Catalog (HICAT) and the Wide-field Infrared Survey...
