Abstract:
The Kyoto tridimensional spectrograph II (3DII) 
is so far the only spectrograph with Fabry-Perot and/or
integral field spectrograph (IFS) modes
on the Subaru Telescope.
Its pixel/lenslet sampling of ~0".1
matches Subaru's excellent image quality.

One of main targets is to resolve activities in galaxies.
The IFS observations of the AGN outflow in NGC 1052
was carried out with the spatial resolution of 0".4.
The decrease of its opening angle with velocity shift
from the systemic velocity both in bluer and redder
velocity channels
is explained only
if the outflow has intrinsically higher-velocity
components inside.
At both sides of the bipolar outflow,
the highest velocity components are detached from the nucleus.
This gap is indicative of some acceleration of matter
or of the existence of undetected, even higher velocity outflow 
components.

The IFS observations of a gravitationally lensed quasar
1RXS J1131-1231 has enabled us to investigate both of
i)
the mass distribution within the lensing galaxy,
including possible dark matter clumps,
and of
ii) the structure of emission line regions of the lensed quasar.
Our accurate measurements,
through post-determined small apertures,
of line flux ratios among 
quasar images have shown that the 
narrow line [OIII] ratios are
consistent with those predicted by smooth-lens
models.
In contrast, the line flux ratios in 
the broad line H_beta emission are anomalous,
most likely caused by a small-mass lens.
We also have found the spatially extended component of
the [OIII] emission.
The asymmetric configurations of this component suggest
asymmetric structure in the narrow line region.

These works have been carried out through collaborations
with non 3DII members.
