This article gives an overview of the constitution, physical conditions, and observables of
dust in the interstellar medium of nearby galaxies. We first review the macroscopic, spatial …

▪ 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 …

We report measurements of the mass density, Ω $\mathstrut {_ {M}} $, and cosmological-
constant energy density, Ω $\mathstrut {_ {{\Lambda}}} $, of the universe based on the …

We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the
redshift range 0.16≤ z≤ 0.62. The luminosity distances of these objects are determined by …

Absolute magnitudes in the B, V, and I bands are derived for nine well-observed Type Ia
supernovae using host galaxy distances estimated via the surface brightness fluctuations or …

ABSTRACT The High-Z Supernova Search is an international collaboration to discover and
monitor Type Ia supernovae (SNe Ia) at z> 0.2 with the aim of measuring cosmic …

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 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) …

We develop a method for estimating the host galaxy dust extinction for type Ia supernovae
based on an observational coincidence first noted by Lira, who found that the BV evolution …
