NED Abstract

Copyright by Royal Astronomical Society. 2007MNRAS.379..909N The supermassive black hole in NGC 4486a detected with SINFONI at the Very Large Telescope N. Nowak, R. P. Saglia, J. Thomas, R. Bender, M. Pannella, K. Gebhardt and R. I. Davies Abstract. The near-infrared (IR) integral field spectrograph SINFONI at the European Southern Observatory Very Large Telescope opens a new window for the study of central supermassive black holes. With a near-IR spatial resolution similar to Hubble Space Telescope optical and the ability to penetrate dust, it provides the possibility to explore the low-mass end of the relation where so far very few black hole masses were measured with stellar dynamics. With SINFONI, we observed the central region of the low-luminosity elliptical galaxy NGC 4486a at a spatial resolution of ~=0.1 arcsec in the K band. The stellar kinematics were measured with a maximum penalized likelihood method considering the region around the CO absorption band heads. We determined a black hole mass of M_{bullet}_;_ = (1.25^+0.75^_-0.79_) x 10^7^ M_sun_ (90 per cent confidence limit) using the Schwarzschild orbit superposition method including the full two-dimensional spatial information. This mass agrees with the predictions of the relation, strengthening its validity at the lower {sigma} end. Key words: galaxies: kinematics and dynamics, galaxies: individual: NGC4486a
