New Constraints on ΩM, ΩΛ, and w from an Independent Set of 11 High-Redshift Supernovae Observed with the Hubble Space Telescope*

TL;DR: In this paper, a set of high-redshift supernovae were used to confirm previous supernova evidence for an accelerating universe, and the supernova results were combined with independent flat-universe measurements of the mass density from CMB and galaxy redshift distortion data, they provided a measurement of $w=-1.05^{+0.15}-0.09$ if w is assumed to be constant in time.

Improved Cosmological Constraints from New, Old, and Combined Supernova Data Sets

Marek Kowalski, +74 more
TL;DR: A new compilation of Type Ia supernovae (SNe Ia), a new data set of low-redshift nearby-Hubble-flow SNe, and new analysis procedures to work with these heterogeneous compilations is presented in this article.

The sloan digital sky survey-II supernova survey: technical summary

Joshua A. Frieman, +108 more
TL;DR: The Sloan Digital Sky Survey-II (SDSS-II) as mentioned in this paper is a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (SNe Ia) using repeated five-band imaging over an area of 300 sq. deg.
