Title:Kinematic standard stars for NIFS

Abstract

This is a proposal to obtain K-band spectra of a number of giant G, K and M stars using NIFS. Our goal is to build a small library of spectra to be used in stellar kinematic studies of nearby galaxies. We are interested, in particular, in using NIFS to to probe the stellar kinematics of the innermost regions of nearby active galaxies. For a few of them, it may be possible to resolve the radius of influence of the nuclear supermassive black hole using NIFS in combination with ALTAIR. As we intend to use the direct pixel fitting technique to obtain velocity dispersions from measurements of the K-band CO absorption features, we need a number of template K-band stellar spectra observed with NIFS.
