Nearby galaxies observed with the Kyoto tridimensional spectrograph II

Abstract

The integral field spectrograph mode of the Kyoto tridimensional spectrograph II is optimized for a high spatial resolution with the ∼ 0″.1 sampling when mounted on the Subaru Telescope, while a wider field of view is emphasized on the University of Hawaii 88-inch Telescope (UH88). One of our main targets is to resolve activities in nearby galaxies. Examples are shown: one is the low ionization emission line region in the galaxy NGC 1052 observed with the Subaru. The spatial resolution of ∼ 0″.4 has revealed the structures, both in space and velocity, of the AGN outflow. An example observed with the UH88 is an interacting galaxy system NGC 6090. Through analyses of the spatial variations of emission line ratios, we have found rapid large-scale metal/abundance enhancement in starbursts. © 2007 Springer-Verlag Berlin Heidelberg.
