cds-question@unistra.fractive-galactic-nucleiline-intensitiesultraviolet-astronomyredshiftedh-i-line-emissionWe conduct an ultraviolet (HST and FUSE) spectroscopic survey of HI (Lyman lines) and seven metal ions (OVI, NV, CIV, CIII, SiIV, SiIII, FeIII) in the low-redshift IGM at z<0.4. We analyzed 650 Ly{alpha} absorbers over redshift path length {Delta}z=5.27, detecting numerous absorbers: 83 OVI systems, 39 CIII, 53 SiIII, 24 CIV, 24 NV, and so on. In the low-z IGM, we have accounted for ~40% of the baryons: 30% in the photoionized Ly{alpha} forest and 10% in the (T=10^5^-10^6^) WHIM traced by OVI. Statistical metallicities are consistent with the canonical value of 10% solar, with considerable scatter.2008ApJ...679..194Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/679/194CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/647/328 : FUSE survey of OVI in ISM (Dixon+, 2006)J/ApJ/643/680 : Imaging and spectroscopy around PKS 0405-123 (Prochaska+,https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/679/194https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/679/194http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/679/194https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/679/194https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/679/194http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/679/194GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/679/194/table1 (FUSE+STIS IGM sight lines)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/679/194/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/679/194/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/679/194/table1?GETtext/xml+votable180.050000true1.5812520.2027780.0055555555555555566/5262 5731 7859 8017 8922 10217 10578 11217 11668 11898 12025 13414 15351 18601 19283 19883 22659 25742 25965 26270 26292 27720 27862 28356 32961 35180 47014 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/679/194?format=asciiUVOpticalRadiodefaultJ/ApJ/679/194/table4O VI detectionsl_W1038Limit flag on W1038meta.code.errorcharrecnoRecord number assigned by the VizieR team.
