We present an empirical method which uses visual band light curve shapes (LCS) to estimate the luminosity of type Ia supernovae (SN Ia). This method is rst applied to a \training set" of 8 SN Ia light curves with independent distance estimates to derive the correlation between the LCS and the luminosity. We employ a linear estimation algorithm of the type developed by Rybicki and Press (1992). The result is similar to that obtained by Hamuy et al. (1995a) with the advantage that LCS produces…

Light Curves of Type Ia Supernovae from Near the Time of Explosion
We present a set of 11 Type Ia supernova (SN Ia) light curves with dense, premaximum sampling. These supernovae (SNe), in galaxies behind the Large Magellanic Cloud (LMC), were discovered by the
Improving the calibration of Type Ia supernovae using late-time light curves
The use of Type la supernovae (SNe Ia) as cosmological standard candles is a key to solving the mystery of dark energy. Improving the calibration of SNe Ia increases their power as cosmological
The Type Ia Supernova 1998bu in M96 and the Hubble Constant
We present optical and near-infrared photometry and spectroscopy of the Type Ia SN 1998bu in the Leo I Group galaxy M96 (NGC 3368). The data set consists of 356 photometric measurements and 29
Results from the High-z Supernova Search Team
Abstract We review the use of Type Ia supernovae for cosmological distance determinations. Low-redshift SNe Ia (z≲0.1) demonstrate that (a) the Hubble expansion is linear, (b) H0=65±2 (statistical)
The Mount Stromlo A bell Cluster Supernova Search
We have initiated a 3 year project to find supernovae in a well-defined sample of high-density southern Abell clusters with redshifts z ≤ 0.08. These observations will provide a volume-limited sample
Type Ia supernova parameter estimation: a comparison of two approaches using current datasets
We compare the traditional χ 2 and complete-likelihood approaches for determining parameter constraints from type Ia supernovae (SNe Ia) when the magnitude dispersion is to be estimated as well. The
The Hubble diagram of type Ia supernovae as a function of host galaxy morphology
We present new results on the Hubble diagram of distant type Ia supernovae (SNe Ia) segregated according to the type of host galaxy. This makes it possible to check earlier evidence for a
The Peak Brightness of Supernovae in the U Band and the Hubble Constant
The peak magnitudes of Type I supernovae in the U band can be used to answer various questions relating to supernovae and the Hubble constant: (1) Well-observed normal Type Ia supernovae are placed
The absolute infrared magnitudes of type ia supernovae
The absolute luminosities and homogeneity of early-time infrared (IR) light curves of type Ia supernovae are examined. Eight supernovae are considered. These are selected to have accurately known
Think Global, Act Local: The Influence of Environment Age and Host Mass on Type Ia Supernova Light Curves
The reliability of Type Ia supernovae (SNIa) may be limited by the imprint of their galactic origins. To investigate the connection between supernovae and their host characteristics, we developed an
