First Science with SHARDS: an ESO-GTC large program
Abstract
SHARDS is an ESO/GTC Large Programme that consists in imaging observations of the entire GOODS-North region in 25 medium-band different filters with GTC/OSIRIS covering the wavelength range between 500 and 950 nm.
The main scientific goal of SHARDS is carrying out an unbiased spectro-photometric survey of passively evolving galaxies at 1.0 < z < 2.5 and measuring stellar population ages through the direct measurement of the Mg(UV) absorption index, which is a distinctive, necessary and sufficient feature of massive quiescent Early Type Galaxies (ETGs) at high redshift. A positive detection of the feature with our spectro-photometric technique can confirm that the galaxies are quiescent and provide us with an estimate of the age of the last star formation burst and the galaxy redshift.
The goal of this talk is to present an updated picture of the current status of the project, including first results from already observed filters and future scientific exploitation and perspectives.
