Abstract:
When the afterglow fades at the site of a long-duration γ-ray
burst (LGRB), Type Ic supernovae (SNe Ic) are the only type of
core-collapse supernova observed. Here we examine 504 supernovae
with types assigned based on their spectra that are located in nearby
(z<0.06) galaxies for which we have constructed surface photometry
from the Sloan Digital Sky Survey (SDSS). The distributions of the
thermonuclear supernovae (SNe Ia) and some varieties of core-collapse
supernovae (SNe II and SNe Ib) follow the galaxy light, but the SNe Ic
(like LGRBs) are much more likely to erupt in the brightest regions of
their hosts.
Description:
Our sample was drawn from 4603 SN discoveries reported to the
International Astronomical Union (IAU) through 2008 March 3, collected
in the Asiago Supernova Catalog (Barbon et al. 1999, Cat. B/sn). We
selected SNe in hosts occurring inside SDSS DR6 coverage with z<0.06.

Note (1): We list data values for SN Ib/Ic and other ambiguously typed SN
as well as SN classified from light curves, even though they are not
included in plots in the main text. Each SN type plotted in this Paper
includes all subtypes and SN with peculiar ("pec") designations. These
subtypes include broad-lined ("Ib-bl") for SN Ic and linear ("IIL"),
plateau ("IIP"), with narrow emission lines ("IIn"), and the
transitional type ("IIb") for SNII.
Note (2): the asterisk (*) indicates a classification made using a light
curve; the other symbols indicate an uncertainty in the classification.
Note (3): The sum of counts registered in all pixels with fewer counts than
measured at the SN location divided by the sum of all counts
associated with the galaxy. See section 3.1 for additional details.
Note (4): For galaxies with bulges, we make an additional calculation of
the fractional flux after removing bulge light by replacing pixels
values inside a circular region encompassing the bulge-dominated
center with the mean of the perimeter pixel values.
