Classifications of the Host Galaxies of Supernovae
Classifications on the DDO system are given for the host galaxies of 177 supernovae (SNe) that have been discovered since 1997 during the course of the Lick Observatory Supernova Search with the Katzman Automatic Imaging Telescope. Whereas SNe Ia occur in all galaxy types, it is found, at a high level of statistical confidence, that SNe Ib, Ic, and II are strongly concentrated in late-type gala...
متن کامل2 00 5 Classifications of the Host Galaxies of Supernovae , Set III
A homogeneous sample comprising host galaxies of 604 recent supernovae, including 212 objects discovered primarily in 2003 and 2004, has been classified on the David Dunlap Observatory system. Most SN 1991bg-like SNe Ia occur in E and E/Sa galaxies, whereas the majority of SN 1991T-like SNe Ia occur in intermediate-type galaxies. This difference is significant at the 99.9% level. As expected, a...
متن کاملDust in the Host Galaxies of Supernovae
We present Spitzer/MIPS 24μm observations of 50 supernova host galaxies at 0.1 < z < 1.7 in the Great Observatories Origins Deep Survey (GOODS) fields. We also discuss the detection of SN host galaxies in SCUBA/850μm observations of GOODS-N and Spitzer/Infrared Spectrograph (IRS) 16μm observations of GOODS-S. About 60% of the host galaxies of both Type Ia and core-collapse supernovae are detect...
متن کامل5 v 1 1 1 A ug 2 00 3 Classifications of the Host Galaxies of Supernovae , Set II
Classifications on the DDO system are given for an additional 231 host galaxies of supernovae that have been discovered during the course of the Lick Observatory Supernova Search with the Katzman Automatic Imaging Telescope (KAIT). This brings the total number of hosts of supernovae discovered (or independently rediscovered) by KAIT, which have so far been classified on a homogeneous system, to...
