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.

TL;DR: In this paper, an extensive time series of spectroscopic data of the peculiar SN 1999aa in NGC 2595 is presented, including 25 optical spectra between -11 and +58 days with respect to B-band maximum light, providing an unusually complete time history.

TL;DR: Conley et al. as discussed by the authors used color information to verify the acceleration of the universe using a blind analysis of Type Ia supernovae with CMAGIC, which has several advantages over current techniques based on maximum magnitudes.

TL;DR: In this article, the authors presented a technique for fitting restframe I-band light curves on a data set of 42 type la supernovae (SNe Ia) and constructed a Hubble diagram with 26 SNe from the subset at 0.01 < z < 0.1.
