(2) The bulge is offset by ~1.8kpc from a brightness minimum at the center of the optically bright inner disk. (3) A tidal stream, possibly associated with an ongoing satellite interaction, extends from the nucleated bulge along the disk. We interpret these properties as the results of one or more non-disruptive mergers between NGC 5523 and companion galaxies or satellites, raising the possibility that some galaxies become isolated because they have merged with former companions.2017A&A...598A.119Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/598/A119CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/598/A119https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/598/A119http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/598/A119https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/598/A119https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/598/A119http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/598/A119GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/598/A119/list (Information on fits file)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/598/A119/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/598/A119/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/598/A119/list?GETtext/xml+votable180.050000true213.7080725.311980.0055555555555555566/8944https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/598/A119?format=asciiOpticaldefaultJ/A+A/598/A119/ellipseOutput file from the Ellipse analysis (from ngc5523_ellipse_analysis.fits file)recnoRecord number assigned by the VizieR team.
