Paul A. Price,Antoinette Songaila,Lennox L. Cowie,J. Bell Burnell,Edo Berger,Antonino Cucchiara,Derek B. Fox,I. M. Hook,Shrinivas R. Kulkarni,Bryan E. Penprase,Katherine C. Roth,Brian P. Schmidt +11 more
TL;DR: In this article, the authors describe the properties of the host galaxy of the gamma-ray burst GRB060510B based on a spectrum of the burst afterglow obtained with the Gemini North 8m telescope.
Journal ArticleDOI

Kronborg,Nathalie Palanque-Delabrouille,Saul Perlmutter,V. Ruhlmann-Kleider,Tianmeng Zhang +30 more
TL;DR: In this paper, the authors measured pseudo-equivalent widths (EWs) of three spectral features (CaII H&K, SiII and MgII) in 144 objects and compared them to the EWs of low-redshift SNe Ia.

TL;DR: In this article, the authors show that the scatter in the SNe Ia Hubble diagram is smallest for SNe occurring in early-type hosts and largest for those occurring in late-type galaxies.
