TL;DR: In this paper, the mass density, Omega_M, and cosmological-constant energy density of the universe were measured using the analysis of 42 Type Ia supernovae discovered by the Supernova Cosmology project.

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.

Sn 2006gy : Discovery of the most luminous supernova ever recorded, powered by the death of an extremely massive star like η carinae
Nathan Smith,Weidong Li,Ryan J. Foley,J. Craig Wheeler,David Pooley,Ryan Chornock,Alexei V. Filippenko,Jeffrey M. Silverman,Robert Quimby,Joshua S. Bloom,Charles E. Hansen +10 more
TL;DR: The Type IIn supernova (SN) 2006gy is the most luminous supernova known to date as discussed by the authors, with a peak visual magnitude of about -22, its very slow rise to maximum took ~70 days, and it stayed brighter than -21 mag for about 100 days.

TL;DR: The Nearby Supernova Factory (SNfactory) as mentioned in this paper is an international experiment designed to lay the foundation for the next generation of cosmology experiments (such as CFHTLS, wP, SNAP and LSST) which will measure the expansion history of the Universe using Type Ia supernovae.
Journal ArticleDOI
Automating Discovery and Classification of Transients and Variable Stars in the Synoptic Survey Era

TL;DR: In this paper, the authors present the inner workings of a framework, based on machine-learning algorithms, that captures expert training and ground-truth knowledge about the variable and transient sky to automate the process of discovery on image differences, and the generation of preliminary science-type classifications of discovered sources.
