Title: The Co-Evolution of Supermassive Black Holes and Galaxies probed with NIFS
Abstract:
Theoretical studies attribute a fundamental role for nuclear supermassive
black holes, via their feeding and the feedback they generate, in the
evolution of galaxies. A number of prescriptions for the physical processes
involved (e.g. gas inflows and outflows) have been assumed in order to
reproduce the so-called M_BH-sigma relation. However, these prescriptions are
not well constrained and are sometimes even at odds with observations of
active galaxies (where these processes occur). We propose to constrain the
relevant physical processes in a systematic way using integral field
spectroscopic observations in the near-IR (J, H and K bands) with the
instrument NIFS+ALTAIR of a well-defined sample of nearby 22 Seyfert
galaxies. Our sample covers a broad range of luminosities and their proximity
allows us to resolve scales of a few to tens of parsecs, ideal to resolve
circum-nuclear inflows and outflows. Our goal is to homogeneously quantify
both the feeding (inflows and also the young stellar population contribution)
and feeedback processes (outflows), and look for correlations with the
Seyfert type and power. For the next semester, we propose such observations
for the galaxies Mrk 607 and Mrk 620.
