  • Green Bank neutral hydrogen survey

    Neutral hydrogen observations at 21cm, made at the Green Bank 91m telescope in 1984, 1985 and 1986, of a large sample of dwarf and other low surface brightness galaxies are...
  • Southern sky survey of 1355 spiral galaxies

    The data from photometric and spectroscopic observations of 1355 southern spiral galaxies are presented and used to determine their distances and peculiar velocities via the...
  • FAST Ultra-Deep Survey: Data Release for FUDS0

    We have used the Five-hundred-meter Aperture Spherical radio Telescope (FAST) to conduct a blind ultradeep survey for neutral hydrogen (HI). We present the complete results from...
  • HI emission line profile of ALFALFA nearby galaxies

    We present a uniform analysis of the integrated profile of the HI emission line of 29958 nearby (z<0.06) galaxies extracted from the ALFALFA 21cm survey. We apply the...
  • Multiwavelength survey of WR stars in LMC

    Surveys of Wolf-Rayet (WR) stars in the Large Magellanic Cloud (LMC) have yielded a fairly complete catalog of 154 known stars. We have conducted a comprehensive,...
  • OH and HI data in molecular clouds

    We have conducted a OH 18cm survey toward 141 molecular clouds in various environments, including 33 optical dark clouds, 98 Planck Galactic cold clumps (PGCCs), and 10 Spitzer...
  • Edge-on HI-rich LSB galaxies from ALFALFA

    Low surface brightness galaxies (LSBGs) are defined as galaxies that are fainter than dark night sky and are important for studying our universe. Particularly, edge-on galaxies...
  • HI 21cm and OH 18cm absorption search with the GBT

    We present the results of a large search for intrinsic HI 21cm and OH 18cm absorption in 145 compact radio sources in the redshift range 0.02<z<3.8 with the Green Bank...
  • ATCA HI absorption survey in Magellanic clouds. I.

    We present the first results from the Small Magellanic Cloud portion of a new Australia Telescope Compact Array HI absorption survey of both of the Magellanic Clouds, comprising...
  • 21-SPONGE HI Absorption Line Survey. I.

    We present 21cm Spectral Line Observations of Neutral Gas with the VLA (21-SPONGE), a Karl G. Jansky Very Large Array (VLA) large project (~600hr) for measuring the physical...
  • The GALFA-HI survey data release 2

    We present the Galactic Arecibo L-Band Feed Array HI (GALFA-HI) survey data release 2 (DR2). The survey covers the 21cm hyperfine transition of Galactic HI from -650 to 650km/s,...
  • Atlas of HI absorption toward HII regions in SGPS I

    We present a complete catalog of H I emission and absorption spectrum pairs, toward H II regions, detectable within the boundaries of the Southern Galactic Plane Survey (SGPS...
  • High-velocity clouds from GASS. I.

    We present a catalog of high-velocity clouds (HVCs) from the Galactic All Sky Survey (GASS) of southern sky neutral hydrogen, which has 57mK sensitivity and 1 km/s velocity...
  • Arecibo Legacy Fast Alfa Survey (ALFALFA) VIII.

    We present a fourth catalog of HI sources from the Arecibo Legacy Fast ALFA (ALFALFA) Survey. We report 541 detections over 136deg^2^, within the region of the sky having...
  • SFI++ II. A new I-band Tully-Fisher catalog

    We present the SFI++ data set, a homogeneously derived catalog of photometric and rotational properties and the Tully-Fisher distances and peculiar velocities derived from them....
  • Catalog of LMC HI clouds

    21cm neutral hydrogen interferometric survey of the Large Magellanic Cloud (LMC) combined with the Parkes multibeam HI single-dish survey (2003MNRAS.339...87S) clearly shows...
  • UCSD/Keck Damped Ly{alpha} Abundance Database

    We publish the Keck/HIRES and Keck/ESI spectra that we have obtained during the first 10 years of Keck observatory operations. Our full sample includes 42 HIRES spectra and 39...
  • Giant molecular clouds in M33

    We present the first interferometric ^12^CO (J=1->0) map of the entire H{alpha} disk of M33. The 13" diameter synthesized beam corresponds to a linear resolution of 50pc,...
  • High-velocity HI observations at 21cm

    Very sensitive HI 21cm observations have been made in 860 directions at {delta}>=-43{deg} in search of weak, Galactic, high-velocity HI emission lines at moderate and high...
  • Gas-rich dwarfs from the POSS-II. III.

    We present Arecibo neutral hydrogen data on a sample of optically selected dwarf galaxies. The sample ranges in H I mass from 10^6^ to 5x10^9^M_{sun}, with a mean of...
