cds-question@unistra.frgalaxiesgalaxy-kinematicsSemi-analytical models in a {Lambda} cold dark matter cosmology have predicted the presence of outlying, 'overmassive' black holes at the high-mass end of the (black hole mass-galaxy velocity dispersion) M_BH_-{sigma} diagram (which we update here with a sample of 89 galaxies). They are a consequence of having experienced more dry mergers - thought not to increase a galaxy's velocity dispersion - than the 'main-sequence' population. Wet mergers and gas-rich processes, on the other hand, preserve the main correlation. Due to the scouring action of binary supermassive black holes, the extent of these dry mergers (since the last significant wet merger) can be traced by the ratio between the central stellar mass deficit and the black hole mass (M_def,*_/M_BH_). However, in a sample of 23 galaxies with partially depleted cores, including central cluster galaxies, we show that the 'overmassive' black holes are actually hosted by galaxies that appear to have undergone the lowest degree of such merging. In addition, the rotational kinematics of 37 galaxies in the M_BH_-{sigma} diagram reveals that fast and slow rotators are not significantly offset from each other, also contrary to what is expected if these two populations were the product of wet and dry mergers, respectively. The observations are thus not in accordance with model predictions and further investigation is required.2015MNRAS.446.2330Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/446/2330CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/146/45 : Spectroscopy of 6 early-type galaxies (Rusli+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/446/2330https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/446/2330http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/446/2330https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/446/2330https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/446/2330http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/446/2330GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/446/2330/table1 (Galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/446/2330/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/446/2330/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/446/2330/table1?GETtext/xml+votable180.050000true210.4244375-11.60698890.0055555555555555566/2374 2622 2709 4439 5075 5182 5196 5599 5975 7037 7132 7355 7424 7606 7941 8195-8196 9287 9368 9672 10379 10856 10912 10977 12025 12241 13128 14744 16655 17754 18269 18325 18935 20282 23306 25083 25100 25647 25669 26055 26125 26803 27186 27342 27512 27515 27604 27714 27718-27719 27735 27743 27765 27767 27773 27907 27913 27936 27938 27944 28015 28200 28221 28251 34493 34535 34540 36231 36247 36261 36861 38703 38868 40294 41586 43233 43262 43289 43619 43828 43891 46399 46568 47397https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/446/2330?format=asciidefaultJ/MNRAS/446/2330/table1Galaxy sampleSimbadNameSimbad column added by the CDSmeta.idcharGalaxyGalaxy namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
