Using natural guide star adaptive optics assisted observations with the Gemini Near-Infrared Integral Field Spectrometer (NIFS) and the natural seeing Gemini Multi-Object Spectrographs-North (GMOS), we derived two-dimensional stellar kinematic maps of NGC 4414 covering the central 1.5-arcsec and 10-arcsec, respectively, at a NIFS spatial resolution of 0.13-arcsec. The kinematic maps reveal a regular rotation pattern and a central velocity dispersion dip down to around 105km/s. We constructed dynamical methods using two different methods: Jeans anisotropic dynamical modeling and axisymmetric Schwarzschild modeling. Both modeling methods give consistent results, but we cannot constrain the lower mass limit and only measure an upper limit for the black hole mass of M_bh_=1.56x10^6^M_{sun}_ (at 3{sigma{ level) which is at least 1{sigma} below the recent Mbh-sigma_e relations. Further tests with dark matter, mass-to-light ratio variation and different light models confirm that our results are not dominated by uncertainties. The derived upper limit mass is not only below the Mbh-sigma_e relation, but is also five times lower than the lower limit black hole mass anticipated from the resolution limit of the sphere of influence. This proves that via high quality integral field data we are now able to push black hole measurements down to at least five times less than the resolution limit.2017A&A...597A..18Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/597/A18CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/597/A18https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/597/A18http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/597/A18https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/597/A18https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/597/A18http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/597/A18GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/597/A18/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/597/A18/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/597/A18/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/597/A18/list?GETtext/xml+votable180.050000true185.6128731.223560.0055555555555555566/28528https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/597/A18?format=asciiOpticalInfrareddefaultJ/A+A/597/A18/listList of fits filesrecnoRecord number assigned by the VizieR team.
