cds-question@unistra.fractive-galactic-nucleispectroscopyapparent-magnitudex-ray-sourcesradio-sourcesWe present an expanded sample of low-mass black holes (BHs) found in galactic nuclei. Using standard virial mass techniques to estimate BH masses, we select from the Fourth Data Release of the Sloan Digital Sky Survey all broad-line active galaxies with masses <2x10^6^M_{sun}_ BHs in this mass regime provide unique tests of the relationship between BHs and galaxies, since their late-type galaxy hosts do not necessarily contain classical bulges. Furthermore, they provide observational analogs of primordial seed BHs and are expected, when merging, to provide strong gravitational signals for future detectors such as LISA. From our preliminary sample of 19, we have increased the total sample by an order of magnitude to 174, as well as an additional 55 (less secure) candidates.2007ApJ...670...92Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/670/92CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/667/131 : Mass function of active black holes (Greene+, 2007)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/670/92https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/670/92http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/670/92https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/670/92https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/670/92http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/670/92GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/670/92/sample (The SDSS extended sample with emission-line measurements, luminosities and mass measurements and radio detections from FIRST)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/670/92/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/670/92/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/670/92/sample?GETtext/xml+votable180.050000true0.2964583-10.03208330.0055555555555555566/1 4115 4122 4151 4155 4171 4196 4226 4237 4260 4750 4838 4847 4848 5002 5033 5079 5099 5100 5103 5370 5437 5455 5479 5500 5541 5563 5566 5569 5582 5587 5628 5631 5662 5698 5715 5730 5770 5862 5890 5910 5931 5939 5946 5955 5959 5977 5982 5983 5985 5988 6098 6115 6139 6166 6396 6490 6504 6564 6571 6588 6589 6599 6600 6611 6617 6631 7169 7173 7181 7227 7258 7273 7288 7298 7299 7320 7432 7466 7479 7485 7488 7536 8740 9053 9085 9150 9170 9242 9441 9444 9465 9601 9730 9750 9771 9812 9824 9869 9883 9923 9957 9972 10085 10214 10515 10658 10702 10730 10839 10869 10878 10879 10979 11056 11065 11067 11072 11097 11109 11191 11209 11241 11253 11254 11354 11405 11419 11438 11445 11446 11843 11851 11875 11909 16891 17215 17229 17259 17308 17555 17557 17565 17773 17777 17825 18028 18063 18077 18084 18299 18367 19021 19023 19048 19121 19137 19417 19456 19697 19778 21982 22005 23194 23211 23233 25837 25919 25926 25936 25948 25982 26019 26167 26260 26265 26296 26402 26405 26411 26414 26525 26606 26948 26973 26999 27005 27043 27077 27081 27098 27105 27227 27229 27342 27358 27364 27370 27375 27428 27447 27524 27590 27801 27815 27823 27873 28171 31146 31315 31316 31323 31406 31436 31459 31656 32509 36724 36763 36767 36780 36792 48989 49097https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/670/92?format=asciiX-rayOpticalRadiodefaultJ/ApJ/670/92/table4ROSAT detectionsrecnoRecord number assigned by the VizieR team.
