Proposed as an ESO/GTC Large Program in March 2009 (PI: Pérez-González, 19 co-I’s).
20 nights awarded in 2010A and 2011A. 2 OSIRIS pointings in GOODS-N with 25 filters each. GTC/Consolider Project approved grant to buy dedicated set of 25 medium-band (FWHM=17 nm) filters.

SHARDS: observational facts
25 filters from 500 to 950 nm: 22 with FWHM=17 nm 3 reddest filters with FWHM=25-35 nm.
Blue filters (l<660 nm) to reach 27.0mag at 3s. Red filters (l>660 nm) to reach 26.5mag at 3s. Exposure times will range from 4 to 30 ks. 2 OSIRIS pointings x25 filters to cover GOODS-N. Detailed calibration needed, including imaging & spectroscopic observations: effect of sky variability, spatial variation of passband,…

December 2009 AEGIS MeetingToledo, December 9-11 2009
SHARDS: Summary Main science case:
Detection of z>1 ETGs, ages with Mg(UV). Examples of other science cases:
Balmer breaks and D(4000) for z<1 sources. Accurate photo-z’s for all sources in field. Stellar population modeling with 25 filters. ELGs: star-forming and AGN.
Program to start in March 2010 Extension to other fields (such as EGS) with other telescopes (such as Subaru)?
