NED Abstract

Copyright by Royal Astronomical Society. 2013MNRAS.428.1790W A blind HI survey in the Ursa Major region Wolfinger, K.; Kilborn, V. A.; Koribalski, B. S.; Minchin, R. F.; Boyce, P. J.; Disney, M. J.; Lang, R. H.; Jordan, C. A. Abstract. We have conducted the first blind HI survey covering 480 deg^2^ and a heliocentric velocity range from 300 to 1900 km s^-1^ to investigate the HI content of the nearby spiral-rich Ursa Major region and to look for previously uncatalogued gas-rich objects. Here we present the catalogue of HI sources. The HI data were obtained with the four-beam receiver mounted on the 76.2-m Lovell telescope [full width at half-maximum (FWHM) 12 arcmin] at the Jodrell Bank Observatory (UK) as part of the HI Jodrell All Sky Survey (HIJASS). We use the automated source finder duchamp and identify 166 H i sources in the data cubes with HI masses in the range of 10^7^-10^10.5^ M_sun_. Our Ursa Major HI catalogue includes 10 first-time detections in the 21-cm emission line. We identify optical counterparts for 165 HI sources (99 per cent). For 54 HI sources (~33 per cent) we find numerous optical counterparts in the HIJASS beam, indicating a high density of galaxies and likely tidal interactions. Four of these HI systems are discussed in detail. We find only one HI source (1 per cent) without a visible optical counterpart out of the 166 HI detections. Green Bank Telescope (FWHM 9 arcmin) follow-up observations confirmed this HI source and its HI properties. The nature of this detection is discussed and compared to similar sources in other HI surveys. Key words: catalogues, surveys, galaxies: fundamental parameters
