M. Newberg,Alexei V. Filippenko,Thomas Matheson,Michael A. Dopita,Warrick J. Couch +33 more
TL;DR: In this article, the authors used a light-curve width-corrected magnitudes as a function of redshift of distant (z = 0.35-0.46) supernovae to obtain a global measurement of the mass density.
Journal ArticleDOI
Measurements of the Cosmological Parameters Omega and Lambda from the First 7 Supernovae at z >= 0.35
Saul Perlmutter,S. Gabi,G. Goldhaber,D. E. Groom,I. M. Hook,A. G. Kim,M. Y. Kim,Janice C. Lee,C. R. Pennypacker,I. Small,A. Goobar,R. Pain,Richard S. Ellis,R. G. McMahon,B. J. Boyle,P. S. Bunclark,D.

TL;DR: In this paper, a technique to systematically discover and study high-redshift supernovae that can be used to measure the cosmological parameters has been developed, based on the initial seven of >28 supernova discovered to date in the Supernova Cosmology Project.
Journal ArticleDOI
The Type Ia Supernova Rate at z ~ 0.4
Reynald Pain,I. M. Hook,Susana E. Deustua,S. Gabi,G. Goldhaber,Donald E. Groom,Alex G. Kim,Min Kook Kim,Julia C. Lee,Carlton R. Pennypacker,Saul Perlmutter,I. A. Small,Ariel Goobar,Richard S. Ellis,Richard G. McMahon,Karl Glazebrook,B. J. Boyle,P. S. Bunclark,David Carter,Mike Irwin +19 more
TL;DR: In this paper, the first measurement of the rate of Type Ia supernovae at high redshift was presented, using a large subset of data from the Supernova Cosmology Project as described in more detail at this meeting.

TL;DR: In this article, the first results from a systematic search for high redshift Type Ia supernovae were reported, and the light curves were all broadened (time dilated) as expected from the expanding universe hypothesis.
