The local properties of supernova explosions and their host galaxies
  We aim to understand the properties at the locations of supernova (SN)
explosion in their host galaxies and compare with the global properties of the
host galaxies. We use the integral field spectrograph (IFS) of Mapping Nearby
Galaxies (MaNGA) at Apache Point Observatory (APO) to get the 2D maps of the
parameter properties for eleven SN host galaxies. The sample galaxies are
analyzed one by one in details on their properties of velocity field, star
formation rate, oxygen abundance and stellar mass etc. This sample of SN host
galaxies have redshifts around $z$ $\sim$ 0.03, which is higher than those of
the previous related works. The higher redshift distribution allows us to
obtain the properties of more distant SN host galaxies. Metallicity (gas-phase
oxygen abundance) estimated from integrated spectra could represent the local
metallicity at SN explosion sites with small bias. All the host galaxies in our
sample are metal-rich galaxies (12+log(O/H) $>$ 8.5) except for NGC 6387, which
means supernovae (SNe) may be more inclined to explode in rich-metallicity
galaxies. There is a positive relation between global gas-phase oxygen
abundance and the stellar mass of host galaxies. We also try to compare the
differences of the host galaxies between SN Ia and SN II. In our sample, both
SNe Ia and SNe II could explode in normal galaxies, while SNe II also could
explode in an interactive or merger system, which has star formation in the
galaxy.
