cds-question@unistra.frsurveysradio-sourcesh-i-line-emissionWe have conducted the first blind HI survey covering 480deg^2^ and a heliocentric velocity range from 300 to 1900km/s 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 HI sources in the data cubes with HI masses in the range of 107-1010.5M_{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%). For 54 HI sources (~33%) 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%) 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.2013MNRAS.428.1790Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/428/1790CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/105/226 : UMa Group (Soderblom+ 1993)J/A+A/370/765 : HI synthesis observations in UMa cluster (Verheijen+, 2001)J/PAZh/27/170 : BR photometry of the UMa galaxy supercluster (Kopylov+, 2001)J/PAZh/27/403 : CCD R photometry in the UMa supercluster (Kopylova+, 2001)J/MNRAS/342/738 : HI Jodrell All Sky Survey (Lang+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/428/1790https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/428/1790http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/428/1790https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/428/1790https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/428/1790http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/428/1790GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/428/1790/table3 (The HI properties of all HIJASS detections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/428/1790/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/428/1790/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/428/1790/table3?GETtext/xml+votable180.050000true162.180541746.71944440.005555555555555556Cone search capability for table J/MNRAS/428/1790/table2 (The HIJASS detections with optical counterparts within the gridded beam size)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/428/1790/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/428/1790/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/428/1790/table2?GETtext/xml+votable180.050000true162.180541746.71944440.0055555555555555565/2724 2744 6/5440 5451 5456 5463 5469 5490 5492 5495 5500 5503 5559 5581 5584 5586-5587 5589-5591 5594-5596 5598-5599 5617 5623 5625 5628-5629 5631 5906 5918 5943 5956 5960 5966-5967 5976 5987 5992 10755 10761-10762 10767 10784 10787 10793 10798-10800 10809 10856 10881 10888-10889 10892 10901 10905 10908 10910-10912 10914 10924-10925 10927 10930 10935 10941 10950 10955 10980 10982 10986 10990-10991 10998-11000 11005-11006 28087 28091 28123 28126 28131 28133 28141 28147 28149 28156 28438 28486-28487 28493 28495-28496 28505 28508 28510-28511 28515-28516 28521 28526 28529 28531 28535 28538 28543 28567 28596 28604 28607-28608 28612 28620 28630-28631 28636-28638 28651 28653 28659 286669.459244390355668e-25 9.459244390355668e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/428/1790?format=asciiRadiodefaultJ/MNRAS/428/1790/table3The HI properties of all HIJASS detectionsrecnoRecord number assigned by the VizieR team.
