cds-question@unistra.frgalaxiesh-i-line-emissionradio-galaxiesUsing archival data from the Hi Parkes All-Sky Survey (HIPASS), we have searched for 21cm line absorption in 204 nearby radio and star-forming galaxies with continuum flux densities greater than S_1.4_~250mJy within the redshift range 0<cz<12000km/s. By applying a detection method based on Bayesian model comparison, we successfully detect and model absorption against the radio-loud nuclei of four galaxies, of which the Seyfert 2 galaxy 2MASX J130804201-2422581 was previously unknown. All four detections were achieved against compact radio sources, which include three active galactic nuclei (AGNs) and a nuclear starburst, exhibiting high dust and molecular gas content. Our results are consistent with the detection rate achieved by the recent ALFALFA (Arecibo Legacy Fast Arecibo L-band Feed Array) Hi absorption pilot survey by Darling et al. and we predict that the full ALFALFA survey should yield more than three to four times as many detections as we have achieved here. Furthermore, we predict that future all-sky surveys on the Square Kilometre Array precursor telescopes will be able to detect such strong absorption systems associated with type 2 AGNs at much higher redshifts, providing potential targets for detection of H_2_O megamaser emission at cosmological redshifts.2014MNRAS.440..696Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/440/696CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)VIII/81 : Sydney University Molonglo Sky Survey (SUMSS V2.1) (Mauch+ 2008)VIII/82 : 2nd Epoch Molonglo Galactic Plane Survey (MGPS-2) (Murphy+, 2007)VIII/73 : HI Parkes All Sky Survey Catalogue (HIPASS) (Meyer+, 2004)VIII/89 : Northern HI Parkes All Sky Survey Catalogue (HIPASS) (Wong+, 2006)J/A+A/544/A18 : Radio galaxies of the local universe (van Velzen+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/440/696https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/440/696http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/440/696https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/440/696https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/440/696http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/440/696GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/440/696/tableb1 (Properties of 204 galaxies searched for HI absorption in HIPASS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/440/696/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/440/696/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/440/696/tableb1?GETtext/xml+votable180.050000true0.7942917-54.74891670.0055555555555555566/18 50 87 90 141 246 4373 4511 8220 8225 8264 8393 8506 8521 8526 8575 8673 8705 8763 16480 16655 16755 17529 17595 17662 17754 17779 18016 18123 18241 18387 18629 18935 19157 19432 19619 20078 20193 20527 20640 20707 20778 20875 21133 21168 21171 21450 21836 22343 22425 22577 22702 23223 23323 23401 23469 23886 24133 24772 24885 25055 25344 25586 25610 25669 25707 25762 25907 26175 26303 26422 26708 26808 26867 27022 27030 27714 27719 27736 27765 27773 27861 27945 28035 28075 28167 28184 28237 28249 29199 29221-29222 29234 29240 29625 31029 31074 31080 31158 31461 31572 32059 32150 32175 32324 33228 33670 33920 33958 33968 34039 34272-34273 34493 34531 34535 34955 34961 34986 35338 35365 35514 35608 35691 35993 36163 36194 36472 36785 36789 38139 38347 38364 38655 38817 38842 39467 39614 39693 39715 39725 39858 39961 39982-39983 40410 40454 41310 41510 41586 41836 41973 42113 42683 43078 43107 43233 43259 43262 43342 43383 43451 43503 43585 43626 43649 43828 43881 43915 43974 43978 43991 44010 44247 44554 44584 44710 44812 45227 45446 45571 45883 45908 46399 46499 46526 46568 46715 46773 47154 47187 47854 48064 48189 48323 48344 48519 489455.585776613014535e-25 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/440/696?format=asciiRadiodefaultJ/MNRAS/440/696/tableb1Properties of 204 galaxies searched for HI absorption in HIPASSSimbadNameSimbad column added by the CDSmeta.idcharNameGalaxy namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
