Recent studies indicate that Type Ia supernovae (SNe Ia) consist of two groups—a "prompt" component whose rates are proportional to the host galaxy star formation rate, whose members have broader light curves and are intrinsically more luminous, and a "delayed" component whose members take several Gyr to explode, have narrower light curves, and are intrinsically fainter. As cosmic star formation density increases with redshift, the prompt component should begin to dominate. We use a two… Expand

The dependence of Type Ia Supernovae luminosities on their host galaxies
Precision cosmology with Type la supernovae (SNe Ia) makes use of the fact that SN Ia luminosities depend on their light-curve shapes and colours. Using Supernova Legacy Survey (SNLS) and other data,Expand
THE MEAN TYPE IA SUPERNOVA SPECTRUM OVER THE PAST NINE GIGAYEARS
We examine the possibility of evolution with redshift in the mean rest-frame ultraviolet (UV; λ ≾ 4500 A) spectrum of Type Ia Supernovae (SNe Ia) sampling the redshift range 0 < z < 1.3. We find newExpand
Evidence of short-lived SN Ia progenitors
We use the VESPA algorithm and spectra from the Sloan Digital Sky Survey to investigate the star formation history of the host galaxies of 257 Type Ia supernovae. We find 5$\sigma$ evidence for aExpand
THE LOCAL HOSTS OF TYPE Ia SUPERNOVAE

The influence of Host Galaxies in Type Ia Supernova Cosmology
We use a sample of 1338 spectroscopically confirmed and photometrically classified Type Ia Supernovae (SNe Ia), sourced from the CSP, CfA, SDSS-II, and SNLS supernova samples, to examine theExpand
Implications of Two Type Ia Supernova Populations for Cosmological Measurements
Recent work suggests that Type Ia supernovae (SNe) are composed of two distinct populations: prompt and delayed. By explicitly incorporating properties of host galaxies, it may be possible to targetExpand
Subluminous Type Ia Supernovae at High Redshift from the Supernova Legacy Survey

THE RELATION BETWEEN EJECTA VELOCITY, INTRINSIC COLOR, AND HOST-GALAXY MASS FOR HIGH-REDSHIFT TYPE Ia SUPERNOVAE
Recently, using a large low-redshift sample of Type Ia supernovae (SNe Ia), we discovered a relation between SN Ia ejecta velocity and intrinsic color that improves the distance precision of SNe IaExpand

We present a sample of 23 spectroscopically confirmed Type Ia supernovae (SNe Ia) that were discovered in the background of galaxy clusters targeted by ROTSE-IIIb and use up to 18 of these toExpand
The Type Ia supernovae rate with Subaru/XMM-Newton Deep Survey
We present measurements of the rates of high-redshift Type Ia supernovae derived from the Subaru/XMM-Newton Deep Survey (SXDS). We carried out repeated deep imaging observations with Suprime-Cam onExpand
