cds-question@unistra.frradial-velocitygalaxy-kinematicsgalaxiesinfrared-astronomyspectroscopyMrk 1216 is a nearby, early-type galaxy with a small effective radius of 2.8kpc and a large stellar velocity dispersion of 308km/s for its K-band luminosity of 1.4x10^11^L_{sun}_. Using integral field spectroscopy assisted by adaptive optics from Gemini North, we measure spatially resolved stellar kinematics within ~450pc of the galaxy nucleus. The galaxy exhibits regular rotation with velocities of +/-180km/s and a sharply peaked velocity dispersion profile that reaches 425km/s at the center. We fit axisymmetric, orbit-based dynamical models to the combination of these high angular resolution kinematics, large-scale kinematics extending to roughly three effective radii, and Hubble Space Telescope imaging, resulting in a constraint of the mass of the central black hole in Mrk 1216. After exploring several possible sources of systematics that commonly affect stellar-dynamical black hole mass measurements, we find a black hole mass of M_BH_=(4.9+/-1.7)x10^9^M_{sun}_ and an H-band stellar mass-to-light ratio of {Upsilon}_H_=1.3+/-0.4{Upsilon}_{sun}_ (1{sigma} uncertainties). Mrk 1216 is consistent with the local black hole mass-stellar velocity dispersion relation, but is a factor of ~5-10 larger than expectations from the black hole mass-bulge luminosity and black hole mass-bulge mass correlations when conservatively using the galaxy's total luminosity or stellar mass. This behavior is quite similar to the extensively studied compact galaxy NGC 1277. Resembling the z~2 quiescent galaxies, Mrk 1216 may be a passively evolved descendant, and perhaps reflects a previous era when galaxies contained over-massive black holes relative to their bulge luminosities/masses, and the growth of host galaxies had yet to catch up.2017ApJ...835..208Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/835/208CatalogResearchIsServedByTAP VizieR generic servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/AJ/113/950 : Kinematic Profiles of S0 Galaxies (Fisher 1997)J/ApJS/152/251 : Indo-US library of coude feed stellar spectra (Valdes+, 2004)J/MNRAS/371/703 : MILES library of empirical spectra (Sanchez-Blazquez+, 2006)J/ApJ/662/808 : Cusp radius in luminous elliptical galaxies (Lauer+, 2007)J/ApJ/690/20 : Models of the AGN and black hole populations (Shankar+, 2009)J/A+A/521/A55 : The mass function of nearby black holes (Caramete+, 2010)J/ApJS/203/24 : Structural param. of galaxies in CANDELS (van der Wel+, 2012)J/AJ/146/45 : Spectroscopy of 6 early-type galaxies (Rusli+, 2013)J/ApJS/218/10 : HET Massive Galaxy Survey (HETMGS) (van den Bosch+, 2015)J/ApJ/808/183 : NGC1271 stellar kinematics (Walsh+, 2015)J/ApJ/826/L32 : Black hole masses in megamaser disk galaxies (Greene+, 2016)J/ApJ/831/134 : BH masses & host galaxy dispersion vel.
