TL;DR: Gaia as discussed by the authors is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach.

TL;DR: In this article, the authors used a light-curve width-corrected magnitudes as a function of redshift of distant (z = 0.35-0.46) supernovae to obtain a global measurement of the mass density.

TL;DR: In this paper, a technique to systematically discover and study high-redshift supernovae that can be used to measure the cosmological parameters has been developed, based on the initial seven of >28 supernova discovered to date in the Supernova Cosmology Project.

TL;DR: In this paper, the authors describe the pipeline architecture being developed to deal with the IR imaging data from WFCAM and VISTA, and discuss the primary issues involved in an end-to-end system capable of: robustly removing instrument and night sky signatures; monitoring data quality and system integrity; providing astrometric and photometric calibration; and generating photon noise-limited images and astronomical catalogues.
