Abstract:
Here we describe the Siding Spring Southern Seyfert Spectroscopic
Snapshot Survey (S7) and present results on 64 galaxies drawn from the
first data release. The S7 uses the Wide Field Spectrograph (WiFeS)
mounted on the ANU 2.3m telescope located at the Siding Spring
Observatory to deliver an integral field of 38x25 arcsec at a spectral
resolution of R=7000 in the red (530-710nm), and R=3000 in the blue
(340-560nm). From these data cubes we have extracted the narrow-line
region spectra from a 4 arcsec aperture centered on the nucleus. We
also determine the Hβ and [OIII]λ5007 fluxes in the narrow
lines, the nuclear reddening, the reddening-corrected relative
intensities of the observed emission lines, and the Hβ and
[OIII]λ5007 luminosities determined from spectra for which the
stellar continuum has been removed. We present a set of images of the
galaxies in [OIII]λ5007, [NII]λ6584, and Hα, which
serve to delineate the spatial extent of the extended narrow-line
region and also to reveal the structure and morphology of the
surrounding HII regions. Finally, we provide a preliminary discussion
of those Seyfert 1 and Seyfert 2 galaxies that display coronal
emission lines in order to explore the origin of these lines.
