Title: Studying the Black Hole in the Compact, High-Dispersion Galaxy Mrk 1216

Abstract: Correlations linking the mass of the black hole in the centers of galaxies to bulge properties have been clearly established over the past decade. However, there still remain major open questions, particularly concerning the sparsely populated upper end of the black hole mass distribution. With an extreme stellar velocity dispersion of \sigma=354 km s^-1, the nearby galaxy Mrk 1216 could host one of the most massive black holes known. This galaxy is rapidly rotating, very compact, and has a small luminosity for its large dispersion, in sharp contrast to the objects typically found at the upper end of the black hole mass - bulge relations. We propose to use AO-assisted NIFS observations to carry out a stellar dynamical measurement of the black hole in the galaxy, leading to a better understanding of the poorly characterized high end of the scaling relationships.
