From magnitudes and redshifts of supernovae, their light-curves, and angular sizes of galaxies to a tenable cosmology
- Physics
- 2012
Early physical cosmologies were based on interpretations of the cosmic redshift for which there was insufficient evidence and on theories of gravitation that appear to be falsified by galactic…

X-ray observations with Chandra and XMM are providing valuable new measurements of the baryonic and dark matter content of groups and clusters. Masses of cD clusters obtained from X-ray and…
Type Ia supernovae: their origin and possible applications in cosmology.
- PhysicsScience
- 1997
Spectroscopic and photometric evidence indicates that Type Ia supernovae (SNe Ia) are the thermonuclear explosions of accreting white dwarfs. However, the progenitor binary systems and hydrodynamical…
A New Upper Limit on the Large Angular Scale Polarization of the Cosmic Microwave Background Radiation

We present a cosmographic study designed to test the simplest type of accelerating cosmology: a flat universe with matter and a cosmological constant ($\Lambda$). Hubble series expansions are fit to…
Einstein's Biggest Blunder? High-Redshift Supernovae and the Accelerating Universe 1
- Physics
- 2001
Nearly 4 years ago, two teams of observational astronomers reported that high-redshift Type Ia supernovae are fainter than expected in a decelerating or freely coasting universe. The radical…
Evidence for the fifth element

This work is based on the first results from a systematic search for high redshift Type Ia supernovae. Using filters in the R-band we discovered seven such SNe, with redshift z = 0.3 — 0.5, before or…
The discovery of a type Ia supernova at a redshift of 0.31
- PhysicsNature
- 1989
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…
Constraints on Cosmological Models from Hubble Space Telescope Observations of High-z Supernovae
