KiDS: the Kilo Degree Survey
KiDS, the Kilo-Degree Survey, is a new, large-scale optical imaging survey in the Southern sky, designed to tackle some of the most fundamental questions of cosmology and galaxy formation of today. Using the VLT Survey Telescope (VST), located at the ESO Paranal Observatory, KiDS will map 1500 square degrees of the night sky in four filters (u, g, r, i).
On this website you will find extensive information about KiDS, including details of the survey specifications, the main scientific drivers, and data availability. Please contact us if you want to know even more about the project!
News: First science results from KiDS published
6 Jul 2015
Today the first scientific results from the Kilo-Degree Survey have been published. Among the first batch of papers are early weak gravitational lensing analyses, demonstrating the power of the superb image quality of KiDS for this type of research. Other results presented include the discovery of four high-redshift quasars, a sample of super-compact massive galaxies, and a catalog of photometric redshift based on machine learning techniques. Links to the papers are provided on the Papers page, and press releases highlighting these first results can be found via the Press releases page.
News: Lensing catalogs available
6 Jul 2015
With the announcement of the first weak lensing analyses using KiDS data, the weak lensing shear catalogs are also released. The area covered is the overlap of the combined data set of the first two KiDS public data releases with the equatorial regions covered by the GAMA survey. Shear measurements are made using a dedicated pipeline using THELI and Lensfit, while the included photometry and photometric redshifts are derived from the DR1/2 coadded images using image gaussianization and Gaussian-weighted aperture photometry.
