Journal ArticleDOI
Implications For The Hubble Constant from the First Seven Supernovae at z >= 0.35
Supernova Cosmology,A. G. Kim,S. Gabi,G. Goldhaber,D. E. Groom,I. M. Hook,M. Y. Kim,Janice C. Lee,C. R. Pennypacker,Saul Perlmutter,I. Small,A. Goobar,R. Pain,Richard S. Ellis,R. G. McMahon,B. J. Boyle,P. S. Bunclark,D. Carter,Mike Irwin,Karl Glazebrook,Heidi Jo Newberg,Alexei V. Filippenko,Thomas Matheson,Michael A. Dopita,W. J. Couch +24 more
TL;DR: In this article, the Supernova Cosmology Project has discovered over twenty-eight supernovae (SNe) at 0.35 = 0.2, and they find that H_0^G < 70 km/s/Mpc in a Lambda=0 universe and H_ 0^G > 78 km/m/MPC in a flat universe, correcting the distant and local SN apparent magnitudes for light curve width.
Journal ArticleDOI
A highly magnified supernova at z=1.703 behind the massive galaxy cluster Abell 1689
Rahman Amanullah,A. Goobar,B. Clement,J. G. Cuby,H. Dahle,Tomas Dahlen,Jens Hjorth,S. Fabbro,Jakob Jonsson,J. P. Kneib,C. Lidman,M. Limousin,B. Milvang-Jensen,Edvard Mörtsell,J. Nordin,K. Paech,J. Richard,Teresa Riehm,Vallery Stanishev,Dan M. Watson +19 more
TL;DR: In this article, the discovery of one of the most distant supernovae ever found, at redshift, z = 1.703, was reported. But this supernova was found in a galaxy with a magnification of only 4.3 × p 0.0.
Journal ArticleDOI
An Intermediate Type Ia Supernova Between Normal And Super-Chandrasekhar
Yi Cao,Joel Johansson,Peter Nugent,A. Goobar,J. Nordin,Shrinivas R. Kulkarni,S. Bradley Cenko,Ori D. Fox,Mansi M. Kasliwal,Christoffer Fremling,Rahman Amanullah,Eric Hsiao,Daniel A. Perley,Brian D. Bue,Frank J. Masci,William H. Lee,N. Chotard +16 more
TL;DR: The early phase spectra of iPTF13asv showed absence of iron absorption, indicating that synthesized iron elements are confined to low-velocity regions of the ejecta, which implies a stratified ejecta structure along the line of sight.

TL;DR: The Supernova/Acceleration Probe (SNAP) as mentioned in this paper is a space-based experiment designed to study the dark energy and alternative explanations of the acceleration of the Universe's expansion by performing a series of complementary systematics-controlled astrophysical measurements.
