Description

In this work, we present the first results of integral-field spectroscopy observations with SINFONI, targeting the inner 400 pc of MCG--6-30-15. This Narrow-Line Seyfert 1 galaxy provides an important test case to probe AGN fuelling at higher X-ray luminosities. With the H-band data, we are able to model and remove the AGN contribution and hence probe the galaxy's stellar and gas kinematics at the best spatial resolution up to now. We discovered a counter-rotating stellar core and extended [Fe II] emission in the central 200 pc region. Using the stellar and ionised gas properties and the observed dynamics, we explore the relation between the counter-rotating core formation and the black hole fuelling, and set constraints on the mass of the black hole.
