Abstract:
We compare the host galaxies of 902 supernovae (SNe), including SNe
Ia, SNe II, and SNe Ibc, which are selected by cross-matching the
Asiago Supernova Catalog (Barbon et al., cat II/227) with the Sloan
Digital Sky Survey (SDSS) Data Release 7 (Strauss et al.,
2002AJ....124.1810S 2002AJ....124.1810S). We selected an additional 213 galaxies by
requiring the light fraction of spectral observations to be >15%,
which could represent well the global properties of the galaxies.
Among these 213 galaxies, 135 appear on the Baldwin-Phillips-Terlevich
diagram, which allows us to compare the hosts in terms of whether they
are star-forming (SF) galaxies, active galactic nuclei (AGNs;
including composites, LINERs, and Seyfert 2s) or absorption-line
galaxies (Absorps; i.e., their related emission lines are weak or
non-existent). The diagrams related to the parameters Dn(4000),
HδA, stellar masses, star formation rates (SFRs), and specific
SFRs for the SNe hosts show that almost all SNe II and most of the SNe
Ibc occur in SF galaxies, which have a wide range of stellar masses
and low Dn(4000). The SNe Ia hosts as SF galaxies following similar
trends. A significant fraction of SNe Ia occurs in AGNs and
absorption-line galaxies, which are massive and have high Dn(4000).
The stellar population analysis from spectral synthesis fitting shows
that the hosts of SNe II have a younger stellar population than hosts
of SNe Ia. These results are compared with those of the 689 comparison
galaxies where the SDSS fiber captures less than 15% of the total
light. These comparison galaxies appear biased toward higher
12+log(O/H) (∼0.1 dex) at a given stellar mass. Therefore, we believe
the aperture effect should be kept in mind when the properties of the
hosts for different types of SNe are discussed.
Description:
We select the SNe and their host galaxies by cross-matching the Asiago
Supernova Catalog (ASC, Barbon et al., cat II/227) with the SDSS DR7
main galaxy sample (MGS, Strauss et al., 2002AJ....124.1810S 2002AJ....124.1810S), only
retaining spectral observations of the SNe host galaxies with good
quality. In this work, we take into account SNe Ia, SNe II, and SNe
Ibc (the latter two as CC-SNe) together to compare the properties of
their hosts. In particular, we will use a stricter selection criterion
to select the objects, for which the 3 arcsec fiber spectra of SDSS
can represent the global properties of the galaxies better. We believe
it is important to show the global properties of SN host galaxies
since it is often difficult to acquire the local properties at the
sites of an SN explosion.
