Query: Spatially-resolved spectroscopy of narrow-line Seyfert 1 host galaxies   We present optical integral field spectroscopy for five $z<0.062$ narrow-line
Seyfert 1 galaxies (NLS1s) host galaxies, probing their host galaxies at
$\gtrsim 2-3$ kpc scales. Emission lines in the nuclear AGN spectra and the
large-scale host galaxy are analyzed separately, based on an AGN-host
decomposition technique. The host galaxy gas kinematics indicates large-scale
gas rotation in all five sources. At the probed scales of $\gtrsim 2-3$ kpc,
the host galaxy gas is found to be predominantly ionized by star formation
without any evidence of a strong AGN contribution. None of the five objects
shows specific star formation rates exceeding the main sequence of low-redshift
star forming galaxies. The specific star formation rates for MCG-05-01-013 and
WPVS 007 are roughly consistent with the main sequence, while ESO 399-IG20, MS
22549-3712, and TON S180 show lower specific star formation rates, intermediate
to the main sequence and red quiescent galaxies. The host galaxy metallicities,
derived for the two sources with sufficient data quality (ESO 399-IG20 and
MCG-05-01-013), indicate central oxygen abundances just below the low-redshift
mass-metallicity relation. Based on this initial case study, we outline a
comparison of AGN and host galaxy parameters as a starting point for future
extended NLS1 studies with similar methods.
