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, confirm the results of Riess and Perlmutter and coworkers that supernova luminosity distances imply an accelerating universe. More importantly, they extend the redshift range of consistently observed Type Ia supernovae (SNe Ia) to z ≈ 1, where the signature of cosmological effects has the opposite sign… 

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,

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

Weak lensing of the high redshift SNIa sample

The current sample of high-redshift Type Ia supernovae (SNeIa), which combines results from two teams, the High-z Supernova Search Team and the Supernova Cosmology Project, is analysed for the

Low Redshift (z < 1) Supernova Studies

The evidence for an accelerating universe, with its implication for the existence of a repulsive dark energy, is of profound significance for particle physics and cosmology. Yet the explanation for


Dark energy and the accelerated expansion of the universe have been the direct predictions of the distant supernovae Ia observations which are also supported, indirectly, by the observations of the

The Type Ia Supernova Rate at z ≈ 0.5 from the Supernova Legacy Survey

We present a measurement of the distant Type Ia supernova (SN Ia) rate derived from the first 2 yr of the Canada-France-Hawaii Telescope Supernova Legacy Survey. We observed four 1° × 1° fields with

Constraining Dark Energy and Cosmological Transition Redshift with Type Ia Supernovae

The property of dark energy and the physical reason for the acceleration of the present universe are two of the most difficult problems in modern cosmology. The dark energy contributes about


Supernova rates (SNRs) are directly coupled to high-mass stellar birth and evolution. As such, they are one of the few direct measures of the history of cosmic stellar evolution. In this paper, we

Imaging and Demography of the Host Galaxies of High-Redshift Type Ia Supernovae

We present the results of a study of the host galaxies of high-redshift Type Ia supernovae (SNe Ia). We provide a catalog of 18 hosts of SNe Ia observed with the Hubble Space Telescope (HST) by the

Gravitational lensing of the SNLS supernovae

Type Ia supernovae have become an essential tool of modern observational cosmology. By studying the distance-redshift relation of a large number of supernovae, the nature of dark energy can be



Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant

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

The Distant Type Ia Supernova Rate

We present a measurement of the rate of distant Type Ia supernovae derived using four large subsets of data from the Supernova Cosmology Project. Within this fiducial sample, which surveyed about 12

Do Type Ia supernovae prove Λ>0?

The evidence for positive cosmological constantfrom Type Ia super- novae is reexamined. Both high redshift supernova teams are found to underestimate the effects of host galaxy extinction. The

The discovery of a type Ia supernova at a redshift of 0.31

OBSERVATIONS indicate that nearby supernova of type Ia have similar peak brightnesses, with a spread of less than 0.3 mag (ref. 1), so that they can potentially be used as 'standard candles' to

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

Type Ia Supernovae, Evolution, and the Cosmological Constant

We explore the possible role of evolution in the analysis of data on Type Ia supernovae (SNe Ia) at cosmological distances. First, using a variety of simple sleuthing techniques, we find evidence

The High-Z Supernova Search: Measuring Cosmic Deceleration and Global Curvature of the Universe Using Type Ia Supernovae

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 deceleration and global curvature. Our

The host galaxies of Type Ia supernovae at z= 0.6

We examine the host galaxies of high-redshift Type Ia supernovae (SNe Ia) using archival I- and R-band data from the Hubble Space Telescope. The SNe Ia host galaxies show a wide variety of


▪ Abstract Distant type Ia supernovae (SNe Ia) appear fainter than their local counterparts. Independent of what explanation will eventually be found to be correct, this implies a significant change

The Type Ia Supernova Rate at z ~ 0.4

We present the first measurement of the rate of Type Ia supernovae at high redshift. The result is derived by using a large subset of data from the Supernova Cosmology Project. Three supernovae were
