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, all types of SNe II are rare in early‐type galaxies, whereas normal SNe Ia occur in all Hubble types… 

Figures and Tables from this paper

Recent studies find that some early-type galaxies host Type II or Ibc supernovae (SNe II, Ibc). This may imply recent star formation activities in these SNe host galaxies, but a massive star origin
Early-type galaxies with core collapse supernovae
Aims. It is widely accepted that the progenitors of core collapse SNe are young massive stars and therefore their host galaxies are mostly spiral or irregular galaxies dominated by a young stellar
Investigating the diversity of supernovae type Iax: a MUSE and NOT spectroscopic study of their environments
SN 2002cx-like Type Ia supernovae (also known as SNe Iax) represent one of the most numerous peculiar SN classes. They differ from normal SNe Ia by having fainter peak magnitudes, faster decline
Paired galaxies with different activity levels and their supernovae
We investigate the influence of close neighbor galaxies on the properties of supernovae (SNe) and their host galaxies using 56 SNe located in pairs of galaxies with different levels of star formation
SN Ia host galaxy properties and the dust extinction distribution.
Type Ia supernovae (SNeIa) display a complex relation with their host galaxies. An important prior to the fit of the supernovae’s light curve is the distribution of host galaxy extinction values that
Two populations of progenitors for type ia supernovae
We use recent observations of the evolution of the Type Ia supernova (SN Ia) rate with redshift, the dependence of the SN Ia rate on the colours of the parent galaxies, and the enhancement of the SN
Active and Star-forming Galaxies and Their Supernovae
To investigate the extent to which nuclear starbursts or other nuclear activity may be connected with enhanced star formation activity in the host galaxy, we perform a statistical investigation of
NGC 2770 has been the host of three supernovae (SNe) of Type Ib during the last ten years, SN 1999eh, SN 2007uy, and SN 2008D. SN 2008D attracted special attention due to the serendipitous discovery
Using light curves and host galaxy spectra of 101 Type Ia supernovae (SNe Ia) with redshift z ≲ 0.3 from the Sloan Digital Sky Survey Supernova Survey (SDSS-SN), we derive the SN Ia rate as a
Supernovae and their host galaxies. I. The SDSS DR8 database and statistics
(Abridged) In this first paper of a series, we report the creation of large and well-defined database that combines extensive new measurements and a literature search of 3876 supernovae (SNe) and
