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 methods that employ relations between SN Ia luminosity and light curve shape. Combined with previous data from our High-z Supernova Search Team and recent results by Riess et al., this expanded set of 16 high-redshift supernovae and a set of 34 nearby supernovae are used to place constraints on the following… 
Type Ia Supernovae and Cosmology
I discuss the use of Type Ia supernovae (SNe Ia) for cosmological distance determinations. Low-redshift SNe Ia (z ≲ 0.1) demonstrate that the Hubble expansion is linear with H 0 = 72±8 km s−1 Mpc−1,
Cosmological Results from High-z Supernovae
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 by similar but distinct methods,
The Accelerating Universe and Dark Energy: Evidence from Type Ia Supernovae
� 0.1) demonstrate that the Hubble expansion is linear, that H0 = 72 ± 8 km s 1 Mpc 1 , and that the properties of dust in other galaxies are similar to those of dust in the Milky Way. The light
Cosmological constraints from supernova data set with corrected redshift
Observations of distant type Ia supernovae (SNe Ia), used as standard candles, support the notion that the Cosmos is filled with a mysterious form of energy, the dark energy. The constraints on
Constraints on cosmological anisotropy out to z = 1 from Type Ia supernovae
A combined sample of 79 high- and low-redshift Type Ia supernovae (SNe) is used to set constraints on the degree of anisotropy in the Universe out to z similar or equal to 1. First, we derive the
Using bright ellipticals as dark energy cosmic clocks
The age of the Universe has been increasingly constrained by different techniques, such as the observations of type Ia supernovae (SNIa) at high redshift or dating the stellar populations of globular
Cosmological parameters from velocities, cosmic microwave background and supernovae
We compare and combine likelihood functions of the cosmological parameters Omega (m), h and sigma (8), from peculiar velocities, cosmic microwave background (CMB) and type la supernovae. These three
Cosmological General Relativity against high redshift observations
Several key relations are derived for Cosmological General Relativity which are used in standard observational cosmology. These include the luminosity distance, angular size, surface brightness and
Cosmological constraints from X-ray AGN clustering and Type Ia supernova data
We put constraints on the main cosmological parameters of different spatially flat cosmological models by combining the recent clustering results of XMM–Newton soft (0.5–2 keV) X-ray sources, which

Feasibility of measuring the cosmological constant {Lambda} and mass density {Omega} using Type Ia supernovae
We explore the feasibility of resurrecting the apparent magnitude-redshift relation for a 'standard candle' to measure the cosmological constant and mass density. We show that type Ia supernovae, if
Gravitational lensing limits on the cosmological constant in a flat universe
Inflationary cosmological theories predict, and some more general aesthetic criteria suggest, that the large-scale spatial curvature of the universe k should be accurately zero (i.e., flat), a
Discovery of a supernova explosion at half the age of the Universe
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 expansion rate. We

The usefulness of type Ia supernovae as distance indicators is a metter of current study and discussion. The avaialbel data suggest that the intrinsic dispersion in the absolute B magnitudes of SNe
Type Ia supernovae in late type galaxies : reddening correction, scale height, and absolute maximum magnitude
We have collected and analyzed the color excess data for the best photometrically studied type Ia supernovae (SN Ia) which occurred in late type galaxies. From these data, a ratio of the B band to

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
Why not consider closed universes
We consider structure formation and CMB anisotropies in a closed universe, both with and without a cosmological constant. The CMB angular power spectrum and the matter transfer function are

We analyze the monopole in the peculiar velocities of 44 Type Ia supernovae (SNe Ia) to test for a local void. The sample extends from 20 to 300 h-1 Mpc, with distances, deduced from light-curve

We have developed a quantitative, empirical method for estimating the age of Type Ia supernovae (SNe Ia) from a single spectral epoch. The technique examines the goodness of fit of spectral features
