▪ Abstract The temporal evolution of the optical spectra of various types of supernovae (SNe)
is illustrated, in part to aid observers classifying supernova candidates. Type II SNe are …

▪ Abstract The focus of this review is the work that has been done during the 1990s on using
Type Ia supernovae (SNe Ia) to measure the Hubble constant (H 0). SNe Ia are well suited …

We present a new and independent determination of the local value of the Hubble constant
based on a calibration of the tip of the red giant branch (TRGB) applied to Type Ia …

The ultimate fate of the Universe, infinite expansion or a big crunch, can be determined by
using the redshifts and distances of very distant supernovae to monitor changes in the …

A spectral-energy distribution (SED) model for Type Ia supernovae (SNe Ia) is a critical tool
for measuring precise and accurate distances across a large redshift range and constraining …

ABSTRACT The High-z Supernova Search Team has discovered and observed eight new
supernovae in the redshift interval z= 0.3–1.2. These independent observations, analyzed …

Aims. We present photometric properties and distance measurements of 252high redshift
Type Ia supernovae (0.15< z< 1.1) discovered during the first three years of the Supernova …

Aims. We present an empirical model of type Ia supernovae spectro-photometric evolution
with time. Methods. The model is built using a large data set including light-curves and …

We report measurements of Ω M, Ω Λ, and w from 11 supernovae (SNe) at z= 0.36–0.86 with
high-quality light curves measured using WFPC2 on the Hubble Space Telescope (HST) …

We present an empirical method that uses multicolor light-curve shapes (MLCSs) to estimate
the luminosity, distance, and total line-of-sight extinction of Type Ia supernovae (SNe Ia) …
