cds-question@unistra.frx-ray-sourcesspectroscopyvisible-astronomysloan-photometryWe search for nearby, isolated, accreting, "stellar-mass" (3-100M_{sun}_) black holes. Models suggest a synchrotron spectrum in visible wavelengths and some emission in X-ray wavelengths. Of 3.7 million objects in the Sloan Digital Sky Survey Early Data Release, Cat. <J/AJ/123/567>, about 150,000 objects have colors and properties consistent with such a spectrum, and 87 of these objects are X-ray sources from the ROSAT All-Sky Survey (Cat. <IX/10> and <IX/29>). Thirty-two of these have been confirmed not to be black holes using optical spectra. We give the positions and colors of these 55 black hole candidates and quantitatively rank them on their likelihood to be black holes. We discuss uncertainties in the expected number of sources and the contribution of black holes to local dark matter.2003ApJ...596..437Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/596/437CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)IX/29 : ROSAT All-Sky Survey Faint Source Catalog (Voges+ 2000)J/AJ/123/567 : SDSS quasar catalog, I: Early Data Release (Schneider+, 2002)J/AJ/126/2209 : X-ray AGN from RASS and SDSS (Anderson+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/596/437https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/596/437http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/596/437https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/596/437https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/596/437http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/596/437GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/596/437/table3 (Spectroscopically selected remnant black hole candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/596/437/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/596/437/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/596/437/table3?GETtext/xml+votable180.050000true15.2425-0.9299720.005555555555555556Cone search capability for table J/ApJ/596/437/table2 (X-ray selected remnant black hole candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/596/437/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/596/437/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/596/437/table2?GETtext/xml+votable180.050000true28.9308330.4686670.0055555555555555566/10063 10065 10073 10085 10092 10094 10098 10106 10179 10181 10183 10185 10188 10189 10191 10192 10194 10203 10213 10214 10221 10222 11587 11588 11589 11590 11593 11595 11596 11599 11602 11608 11617 17662 17749 17750 17763 17818 17828 17829 17856 18020 18021 18022 18032 18062 18067 18092 18176 18770 23187 23189 23191 23196 23204 23209 25935 25947 25956 26010 26034 26194 26203 26212 26216 26220 26253 26278 26279 26281 26282 26284 26285 26369 26942 26957 26967 26969 26970 26974 26983 26992 27025 27044 27050 27074 27225 27243 31379 31382 31384 31386 31396 31398 31401 314082.040811542443644e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/596/437?format=asciiX-rayOpticaldefaultJ/ApJ/596/437/table3Spectroscopically selected remnant black hole candidatesrecnoRecord number assigned by the VizieR team.
