A Supernova at z = 0.458 and Implications for Measuring the Cosmological Deceleration
S. Perlmutter, C. R. Pennypacker, G. Goldhaber +20
We have begun a program to discover high-redshift supernovae ( 0.25--0.5), and study them with follow-up photometry and spectroscopy. We report here our first discovery,…

Feasibility of Measuring the Cosmological Constant Lambda and Mass Density Omega using Type Ia Supernovae
Ariel Goobar, Saul Perlmutter
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 ty…
