cds-question@unistra.frredshiftedgalaxiesinfrared-sourcesradio-galaxiesTo increase the redshift range and look-back time over which the radio luminosity function can be measured directly, we identified 1157 galaxies in the Las Campanas Redshift Survey (LCRS, Cat. <VII/203>) having isophotal (red) magnitudes m_ISO_<=18.0 with radio sources brighter than 2.5mJy/beam in the 1.4GHz NRAO VLA Sky Survey (NVSS, 1998AJ....115.1693C). Since the NVSS has 45" FWHM angular resolution, these radio and optical limits include nearly all LCRS galaxies with 1.4GHz luminosities L>=10^22.4^W/Hz at z~0.05 to L>=10^23.6^W/Hz at z~0.2. The mean redshift <z>~0.14 of the radio-detected galaxies is higher than the mean redshift <z>~0.10 of the optical sample. This indicates that, statistically, the radio emission was detected from galaxies with the highest optical luminosities. Of the 1157 galaxies, 261 were also identified with far-infrared (FIR) sources in the IRAS Point Source Catalog and Faint Source Catalog. The principal radio energy sources in all identified galaxies were classified as either "starburst" or "AGN" on the basis of their FIR-radio flux ratios, FIR spectral indices, and radio-optical flux ratios. We show that the radio-optical flux ratio can be effectively used to classify the dominant energy source for the radio emission even if FIR fluxes and radio morphological data are not available.1999ApJS..123...41Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/123/41CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/203 : Las Campanas Redshift Survey (Shectman+ 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/123/41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/123/41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/123/41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/123/41https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/123/41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/123/41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/123/41/table2 (Optical, radio, and infrared data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/123/41/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/123/41/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/123/41/table2?GETtext/xml+votable180.050000true151.82975-2.90722220.0055555555555555565/4097 4098 6269 6370 6383 6387 6388 6391 6392 6417 6472 6535 6689 6708 6711 6712 6715 6716 6723 8606 8626 8798 8813 8818 8862 8961 11198 11256 11629 11694 11714 12033 6/16400 16416 25071 25075 25080 25081 25082 25329 25331 25334 25336 25337 25338 25340 25389 25390 25391 25393 25394 25395 25396 25397 25398 25400 25401 25402 25411 25412 25413 25415 25417 25418 25462 25463 25465 25466 25467 25469 25470 25471 25473 25474 25475 25476 25477 25478 25484 25488 25527 25531 25541 25542 25543 25547 25572 25575 25576 25581 25582 25583 25584 25585 25586 25592 25629 25631 25647 25651 25654 25656 25657 25667 25672 25673 25675 25676 25680 25696 25717 25719 25723 25724 25725 25726 25731 25732 25733 25736 25738 25781 25782 25783 25786 25787 25788 25789 25790 25798 25799 25801 25804 25805 25806 25808 25809 25810 25816 25821 25822 25823 25824 25825 25826 25832 25835 25837 25838 25839 25841 25842 25843 25844 25848 25849 25867 25868 25869 25870 25873 25874 25880 25883 25887 25892 25895 25899 25901 25902 25905 25907 25908 25912 25913 25920 25922 25924 25926 25928 25929 25930 25985 25986 25989 25992 25994 26118 26119 26121 26123 26124 26126 26127 26129 26130 26135 26136 26146 26151 26152 26157 26161 26162 26163 26164 26165 26166 26168 26177 26178 26179 26180 26181 26184 26185 26241 26242 26243 26244 26246 26248 26654 26655 26671 26676 26677 26680 26681 26682 26684 26690 26691 26692 26693 26694 26696 26698 26699 26704 26741 26742 26743 26745 26748 26749 26750 26753 26755 26768 26805 26807 26812 26813 26815 26823 26825 26826 26827 26828 26829 26830 26839 26855 26856 26868 26870 26872 26885 26887 26889 26890 26891 26896 26897 26899 26900 26904 26907 26908 26910 26913 26914 26919 26920 26925 26926 26930 26931 26932 26933 26937 26938 26945 26946 26947 26948 26950 26954 27009 27011 27012 27016 27017 27203 27204 31361 31363 31364 31368 31369 31370 34399 34415 34420 34421 34463 34479 34483 34484 34485 34486 34488 34490 34491 34500 34501 34502 34508 34528 34563 34564 34565 34566 34569 34570 34571 35167 35187 35189 35190 35247 35251 35256 35257 35258 35260 35267 35269 35296 35443 35444 35446 35447 35507 35508 35509 35511 35512 35513 35514 35516 35523 35524 35525 35526 35528 35529 35530 35588 35591 35592 35593 35595 35596 35616 35849 35850 35852 35856 44767 44785 44787 44790 44847 44853 44855 44856 44857 44858 44867 44868 44869 44875 44930 44933 44934 44936 44937 44938 44940 44960 44983 44989 44990 45001 45003 45004 45005 45006 45008 45009 45010 45016 45021 45023 45028 45032 45037 45038 45040 45041 45043 45044 45045 45046 45048 45050 46431 46447 46453 46454 46455 46456 46457 46458 46460 46495 46511 46515 46520 46521 46522 46531 46532 46533 46534 46536 46537 46538 46540 46544 46687 46708 46709 46710 46714 46715 46751 46767 46773 46774 46775 46787 46789 46792 46793 46794 46800 46851 46852 46853 46854 46864 46880 48144https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/123/41?format=asciiOpticalInfraredRadiodefaultJ/ApJS/123/41/table2Optical, radio, and infrared datarecnoRecord number assigned by the VizieR team.
