cds-question@unistra.frgalaxiesphotometryvisible-astronomysloan-photometryA spiral galaxy partially overlapping a more distant elliptical offers a unique opportunity to measure the dust extinction in the foreground spiral. From the Sloan Digital Sky Survey (SDSS) DR4 spectroscopic sample, we selected 83 occulting galaxy pairs and measured disk opacity over the redshift range z=0.0-0.2 with the goal of determining the recent evolution of disk dust opacity. The enrichment of the ISM changes over the lifetime of a disk, and it is reasonable to expect the dust extinction properties of spiral disks as a whole to change over their lifetime. When they do, the change will affect our measurements of galaxies over the observable universe. From the SDSS pairs we conclude that spiral disks show evidence of extinction to ~2 effective radii.2007AJ....134.2385Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/2385CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/134/2385https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/2385http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/2385https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/2385https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/2385http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/2385GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/134/2385/table1 (SDSS basic data of the occulting galaxy pairs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/134/2385/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/134/2385/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/134/2385/table1?GETtext/xml+votable180.050000true148.311890.649980.0055555555555555566/5019 5034 5098 5532 5698 5776 5853 5898 5984 6008 6026 6236 6247 6494 6541 6545 6593 6602 6644 7195 7212 7379 7556 8703 9055 9247 9301 9504 9641 9656 9743 9776 9954 10092 10862 10997 11001 11002 11037 11049 11124 11176 11203 11220 11231 11265 11398 11432 11434 11448 11458 11490 11846 11875 17771 17778 17819 23058 23209 25599 25992 26333 26345 26384 26970 26983 26991 27046 27078 27102 27246 27291 27381 27394 27447 27622 27760 27782 27827 28174 31387 32502 490992.040811542443644e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/134/2385?format=asciiOpticaldefaultJ/AJ/134/2385/table1SDSS basic data of the occulting galaxy pairsrecnoRecord number assigned by the VizieR team.
