cds-question@unistra.fractive-galactic-nucleiastrophysical-masersradio-astronomyWe report the discovery of water maser emission in five active galactic nuclei (AGNs) with the 100m Green Bank Telescope (GBT). The positions of the newly discovered masers, measured with the VLA, are consistent with the optical positions of the host nuclei to within 1{sigma} (0.3" radio and 1.3" optical) and most likely mark the locations of the embedded central engines. The spectra of three sources, 2MASX J08362280+3327383, NGC 6264, and UGC 09618 NED02 (PGC 053432), display the characteristic spectral signature of emission from an edge-on accretion disk with maximum orbital velocity of ~700, ~800, and ~1300km/s, respectively. We also present a GBT spectrum of a previously known source, Mrk 0034, and interpret the narrow Doppler components reported here as indirect evidence that the emission originates in an edge-on accretion disk with orbital velocity of ~500km/s .2006ApJ...652..136Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/652/136CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/652/136https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/652/136http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/652/136https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/652/136https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/652/136http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/652/136GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/652/136/table1 (Galaxies surveyed for water maser emission with the Green Bank Telescope)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/652/136/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/652/136/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/652/136/table1?GETtext/xml+votable180.050000true3.0742917-0.10294440.0055555555555555566/135 698 4556 4574 4602 4835 4858 5221 5293 5660 8215 8223 8269 8291 8526 8830 9503 9714 9997 10020 10294 10348 11646 13120 13376 15289 17237 17506 17701 18053 18070 18086 18126 18365 18400 18869 19524 19618 19625 20061 22634 23451 26303 26374 27486 27771 28412 28516 31535 31546 36299https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/652/136?format=asciiRadiodefaultJ/ApJ/652/136/table1Galaxies surveyed for water maser emission with the Green Bank TelescoperecnoRecord number assigned by the VizieR team.
