TL;DR: In this article, the authors present a new compilation of Type Ia supernovae (SNe Ia), a new dataset of low-redshift nearby-Hubble-flow SNe and new analysis procedures to work with these heterogeneous compilations.

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.

Effects of Explosion Asymmetry and Viewing Angle on the Type Ia Supernova Color and Luminosity Calibration
Keiichi Maeda,Giorgos Leloudas,S. Taubenberger,M. Stritzinger,Jesper Sollerman,N. Elias-Rosa,S. Benetti,Mario Hamuy,G. Folatelli,Paolo A. Mazzali +9 more
TL;DR: In this paper, the color and luminosity residual are related to the wavelength shift of nebular emission lines observed at approximately 150 days after maximum light, and it is suggested that the viewing direction is a dominant factor controlling the SN color and that a large part of the color variations is intrinsic, rather than due to the host extinction.
