Spatially Resolved Properties of Supernova Host Galaxies in SDSS-IV
  MaNGA
  We crossmatch galaxies from Mapping Nearby Galaxies at Apache Point
Observatory with the Open Supernova Catalog, obtaining a total of 132 SNe
within MaNGA bundle. These 132 SNe can be classified into 67 Type Ia and 65
Type CC. We study the global and local properties of supernova host galaxies
statistically. Type Ia SNe are distributed in both star-forming galaxies and
quiescent galaxies, while Type CC SNe are all distributed along the
star-forming main sequence. As the stellar mass increases, the Type Ia/CC
number ratio increases. We find: (1) there is no obvious difference in the
interaction possibilities and environments between Type Ia SN hosts and a
control sample of galaxies with similar stellar mass and SFR distributions,
except that Type Ia SNe tend to appear in galaxies which are more
bulge-dominated than their controls. For Type CC SNe, there is no difference
between their hosts and the control galaxies in galaxy morphology, interaction
possibilities as well as environments; (2) the SN locations have smaller
velocity dispersion, lower metallicity, and younger stellar population than
galaxy centers. This is a natural result of radius gradients of all these
parameters. The SN location and the its symmetrical position relative to the
galaxy center, as well as regions with similar effective radii have very
similar [Mg/Fe], gas-phase metallicity, gas velocity dispersion and stellar
population age.
