cds-question@unistra.fractive-galactic-nucleiquasarsphotometryredshiftedWe present and discuss optical imaging of 76 active galactic nuclei (AGNs) that represent the selected Two Micron All Sky Survey (2MASS) sample for z<0.3, from a full list of 243. They are found to have dust-obscured nuclei, residing in host galaxies that show a high fraction (greater than 70%) of tidal interactions. The derived luminosities of the AGNs and host galaxies are similar to traditionally selected AGNs, and they may comprise some 40% of the total AGN population at low redshift. We have measured a number of host galaxy properties and discuss their distributions and interrelations. We compare the 2MASS AGNs with optically selected samples and the IRAS-selected galaxy samples and discuss the differences in terms of merger processes and initial conditions.2003AJ....126...63Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/126/63CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/126/63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/126/63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/126/63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/126/63https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/126/63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/126/63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/126/63/table1 (2MASS sample and measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/126/63/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/126/63/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/126/63/table1?GETtext/xml+votable180.050000true33.91-15.17011110.0055555555555555566/27 74 236 429 530-531 534 4443 5071-5072 5074 5285 5300 5697 5711 5732 6078 6413 6593 7375 7397 8264 8273 8390 8587 8590 8612 8636 8973 9208 9246 9779 10522 10591 10647 11283 11356 21148 21177 22583 23153 23254 23348 23437 24725 24923 24927 25239 25323 25325 25363 25366 25420 26378 26393 26410 26572 26593 27075 27225 27357 27529 28031 28175 28196 28232 28238 28374 31456 36183 36559 44463 44852 44873 485618.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/126/63?format=asciiOpticaldefaultJ/AJ/126/63/table12MASS sample and measurementszRedshiftsrc.redshiftfloatrecnoRecord number assigned by the VizieR team.
