Abstract:
We have observed the nearby, nearly face-on, Seyfert 2 galaxy,
NGC 5427, using optical integral field spectroscopy of both the
nuclear regions and the HII regions in the spiral arms. The observed
spectra have been modelled using the MAPPINGS IV photoionisation code,
both to derive the chemical abundances in the HII regions and the
Seyfert nucleus, and to constrain the EUV spectral energy distribution
of the AGN illuminating the extended narrow-line region.
Description:
The six fields on NGC 5427 were observed using the Wide Field
Spectrograph (WiFeS, Dopita et al. 2010Ap&SS.327..245D 2010Ap&SS.327..245D) at the ANU
2.3m telescope at Siding Spring (Australia) on 2010 June 12-14 under
non-photometric conditions. The data were obtained using the R_S∼3000
grating in the blue (B3000) and the R_S∼7000 grating in the red
(R7000) and cover a total wavelength region from 3500 Å to 7016
Å. The data were reduced using an adapted version of PyWiFeS 0.5.0
(Childress et al. 2014Ap&SS.349..617C 2014Ap&SS.349..617C). The data cubes have spatial
pixels of 1x1arcsec2. The telescope pointing used for each of the
six fields is reported in the header RA and DEC keywords.
