di↵erent SN types. In this first study of a series we focus on the properties related with star formation (SF). We recover the sequence
in association of di↵erent SN types to the star-forming regions by using several indicators of the ongoing and recent SF related to
both the ionized gas and the stellar populations. While the total ongoing SF is on average the same for the three SN types, SNe Ibc/IIb
tend to occur closer to star-forming regions and in higher SF density locations than SNe II and SNe Ia; the latter shows the weakest
correlation. SNe Ia host galaxies have masses that on average are ⇠0.3-0.8 dex higher than those of the core collapse (CC) SNe hosts
because the SNe Ia hosts contain a larger fraction of old stellar populations. Using the recent SN Ia delay-time distribution and the
SFHs of the galaxies, we show that the SN Ia hosts in our sample are expected to produce twice as many SNe Ia as the CC SN hosts.
Since both types occur in hosts with a similar SF rate and hence similar CC SN rate, this can explain the mass di↵erence between the
SN Ia and CC SN hosts, and reinforces the finding that at least part of the SNe Ia originate from very old progenitors. By comparing
the mean SFH of the eight least massive galaxies with that of the massive SF SN Ia hosts, we find that the low-mass galaxies formed
their stars during a longer time (0.65%, 24.46%, and 74.89% in the intervals 0–0.42 Gyr, 0.42–2.4 Gyr, and > 2.4 Gyr, respectively)
than the massive SN Ia hosts (0.04%, 2.01%, and 97.95% in these intervals). We estimate that the low-mass galaxies produce ten
Collaboration
times fewer SNe Ia and three times fewer CC SNe than the high-mass group. Therefore the ratio between the number of CC SNe and
SNe Ia is expected to increase with decreasing galaxy mass. CC SNe tend to explode at positions with younger stellar populations
than the galaxy average, but the galaxy properties at SNe Ia locations are one average the same as the global galaxy properties.

ABSTRACT
1. Introduction
We present the second study using optical Integral Field Spectroscopy (IFS) of nearby supernova (SN) host galaxies (0.005 < z < 0.03)
to characterize the environmental parameters at the location of di↵erent SN types. We increased the sample from Galbany
et al. (2014)
Supernova
(SN) explosions are one of the key processes that
with 29 objects, which makes a total sample of 125 SNe of all types in 110 galaxies. In this work we focused ondrive
studying
the SN evolution of galaxies. Throughout their lifethe chemical
environmental metallicities, for which wide-field IFS enables proper comparisons of di↵erent approaches. Using the

stars
fuse lighter into heavier chemical elements in their
from Marino et al. (2013), we found that the average metallicity at the location of SNe Ia is higher than at the position
of
CC
cores, andSNe
the by
explosion at the end of a star’s life is responsible
0.05 dex, being similar but slightly higher for Ibc than for SN II. While the central and total metal abundances are similar for CC SN
for dispersing the newly synthesized heavy elements into the inand SNIa hosts, the stellar metallicity of SN Ia host is significantly higher than that of CC SN host galaxies (< Z>⇠ 0.010). When
terstellar
medium
the AGN contribution is excluded from the total spectra, the average metallicity of the SNe Ia host galaxies is 0.03
dex higher
than (ISM). The next generation of stars form from
gas

has
already been enriched by heavier elements. Thus,
the measured not excluding the AGN. This can be interpreted as a systematic e↵ect when measuring metallicities of galaxies which
starting
from
gas consisting of only H, He, and a tiny fraction of
structure cannot be resolved (dwarf galaxies at lower redshifts or any galaxy at higher redshifts). By comparing the SN environmental
Li, the heavy-element content of galaxies gradually increases to
collapse SNe (CC SNe). The end product of stars with m
between ⇠0.5 and 8 M is a degenerate carbon-oxygen (
white dwarf (WD) (Becker & Iben 1980). The upper mass
of C/O WDs is ⇠ 1.1 M (Dominguez et al. 1999), but if
a star can increase its mass to ⇠1.4 M , thermonuclear reac
can ignite in the center and the WD can be completely disru
in a very bright thermonuclear explosion that leads to a ty
SN (SNe Ia, Hoyle & Fowler 1960). CC SNe disperse
amounts of intermediate mass elements (IME) such as oxyg
carbon, but most of the synthesized iron-group elements re
