  • WSRT wide-field HI survey. II.

    We have used the Westerbork array to carry out an unbiased wide-field survey for HI emission features, achieving an RMS sensitivity of about 18mJy/Beam at a velocity resolution...
  • Starbursts in barred spiral galaxies. VI.

    This paper reports a study of the effect of a bar on the neutral hydrogen (HI) content of starburst and Seyfert galaxies. We also make comparisons with a sample of "normal"...
  • CO observation of isolated galaxies

    We present ^12^CO(J=1-0) line observations of 99 galaxies obtained with the SEST 15m, the Kitt Peak 12m and the IRAM 30m telescopes. The target galaxies were selected from the...
  • LSB galaxies in near-infrared. II.

    A total of 367 Low Surface Brightness galaxies detected in the 2MASS all-sky near-infrared survey have been observed in the 21 cm H I line using the Arecibo telescope. All have...
  • LSB galaxies in near-infrared. III.

    A total of 334 Low Surface Brightness galaxies detected in the 2MASS all-sky near-infrared survey have been observed in the 21 cm H I line using the Nancay telescope. All have a...
  • Background galaxies in the WSRT wide-field Survey

    We have used the Westerbork array to carry out an unbiased wide-field survey for H I emission features, achieving an RMS sensitivity of about 18mJy/beam at a velocity resolution...
  • HI survey of polar ring galaxies. IV.

    A total of 33 polar ring galaxies and polar ring galaxy candidates were observed in the 21-cm HI line with the 64-m Parkes radio telescope. The objects, selected by their...
  • Fourth list of the Karachentsev catalog

    This paper presents HI observations of 165 dwarf galaxy candidates from the Karachentsev catalog of candidates for nearby dwarf galaxies prepared from film copies of POSSII and...
  • HI observations of nearby dwarf galaxies

    We carried out a systematic search for nearby dwarf galaxies in the northern sky based on POSS-II film copies. As a result we present a list of 101 nearby dwarf galaxy...
  • HI observations of LSB galaxies

    We have used the Nancay Radio Telescope to obtain new global HI data for 16 giant low surface brightness (LSB) galaxies. Our targets have optical luminosities and disk scale...
  • Hydrogen-line survey of M31. III. HI Holes

    An analysis is carried out of HI holes in M 31 as detected with the Westerbork radiotelescope (WSRT). The holes range from 100-1000pc across and represent missing masses ranging...
  • HI data for 392 spiral galaxies

    392 spiral galaxies with type Sb or later have been detected in the 21-cm line of neutral hydrogen with the Nancay radiotelescope, and among them 172 HI fluxes are obtained for...
  • Argentina High-Latitude H I Survey

    This survey consists of H I 21-cm spectra covering the southern sky with absolute galactic latitude |b|>10 degrees and a declination dec<-25 degrees. The observations were...
  • Parkes High-Latitude H I Survey

    This survey consists of HI 21-cm spectra covering the southern sky with absolute galactic latitude |b|>=10 degrees and declination dec<=-30 degrees. The observations were...
  • Northern HI Parkes All Sky Survey Catalogue (HIPASS)

    The Northern HIPASS catalogue (NHICAT) is the northern extension of the HIPASS catalogue, HICAT. This extension adds the sky area between the declination (Dec.) range of...
  • Hat Creek High-Latitude H I Survey

    This survey consists of H I 21-cm spectra covering the entire northern sky with absolute Galactic latitude |b|>10 degrees and declination dec>-30degrees. The observations...
  • HI spectral properties of galaxies

    We present a homogeneous compilation of HI spectral parameters extracted from global 21cm line spectra for some 9000 galaxies in the local universe (heliocentric velocity -200
  • Leiden/Argentine/Bonn (LAB) Survey of Galactic HI

    The LAB survey contains the final data release of observations of 21-cm emission from Galactic neutral hydrogen over the entire sky, merging the Leiden/Dwingeloo Survey (LDS:...
  • HI survey of the sky DE<+25{deg}

    We present the final data release of the high sensitivity {lambda}21-cm neutral hydrogen survey of the sky south of {delta}<=-25{deg}. A total of 50980 positions lying on a...
  • HI Parkes All Sky Survey Catalogue (HIPASS)

    The HI Parkes All-Sky Survey (HIPASS) Catalogue forms the largest uniform catalogue of HI sources compiled to date, with 4315 sources identified purely by their HI content. The...
