cds-question@unistra.frgalaxiesactive-galactic-nucleiradial-velocitygalaxy-kinematicsaccretionUsing adaptive optics assisted Gemini/NIFS data, I study the present and past gas accretion in the central 3" of the M32 nucleus. From changes in the spectral slope and CO line depths near the center, I find evidence for unresolved dust emission resulting from black hole (BH) accretion. With a luminosity of ~2x10^38^erg/s, this dust emission appears to be the most luminous tracer of current BH accretion, 2 orders of magnitude more luminous than previously detected X-ray emission. These observations suggest that using high-resolution infrared data to search for dust emission may be an effective way to detect other nearby, low-luminosity BHs, such as those in globular clusters. I also examine the fossil evidence of gas accretion contained in the kinematics of the stars in the nucleus. The higher order moments (h3 and h4) of the line-of-sight velocity distribution show patterns that are remarkably similar to those seen on larger scales in elliptical galaxies and in gas-rich merger simulations. The kinematics suggests the presence of two components in the M32 nucleus, a dominant disk overlying a pressure supported component.2010ApJ...725..670Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/725/670CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/539/A138 : RR Lyr variable stars in M32 (Fiorentino+, 2012)J/ApJ/708/817 : RR Lyrae variables in M32 and M31 (Fiorentino+, 2010)J/ApJS/183/1 : Catalog of central stellar velocity dispersions (Ho+, 2009)J/ApJ/707/890 : IR properties of E and S0 galaxies (Temi+, 2009)J/ApJ/702/955 : K-band luminosity function from 2MASX (Devereux+, 2009)J/MNRAS/382/1552 : Multiwavelength study of nearby galaxy nuclei (Lira+, 2007)J/ApJ/532/308 : Hot Horizontal Branch Stars in the Core of M32 (Brown+ 2000)J/ApJ/504/113 : F175W and F275W photometry of M31 and M32 (Brown+, 1998)J/A+AS/127/117 : Kinematics of galaxies (Prugniel+ 1998)J/ApJS/112/315 : Spectroscopic parameters of Seyfert nuclei (Ho+ 1997)J/AJ/104/1349 : Infrared-luminous giants in M32 (Freedman, 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/725/670https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/725/670http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/725/670https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/725/670https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/725/670http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/725/670GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/725/670/table1 (Gemini/NIFS kinematic data of the M32 nucleus)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/725/670/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/725/670/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/725/670/table1?GETtext/xml+votable180.050000true10.6742927840.865240280.0055555555555555566/2622https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/725/670?format=asciiOpticaldefaultJ/ApJ/725/670/table1Gemini/NIFS kinematic data of the M32 nucleusrecnoRecord number assigned by the VizieR team.
