Resum

In this talk I will introduce the SHARDS (Survey for High-z Absorption 
Red & Dead Sources; Perez-Gonzalez P.G., Cava A., Barro G. et al. 2013) 
project, an unbiased ultra-deep spectro-photometric survey with 
OSIRIS en GTC aimed at selecting and studying massive passively evolving 
galaxies at z=1.0-2.3 using a set of 24 medium-band filters (FWHM ~17 
nm) at 500-950 nm in GOODS-N. Our observing strategy is optimized to 
detect at z>1 the prominent MgUV absorption feature at rest-frame ~280 
nm, a distinctive, necessary, and sufficient feature of evolved stellar 
populations. Nonetheless, the data quality allow a plethora of studies 
on galaxy populations, including Emission Lines Galaxies (ELGs) about 
which we have started one of our first science verification projects. 
The first analysis of ELGs in SHARDS, demonstrate the huge capability of 
this survey in providing physical information for a large sample of 
emitters, spanning from local H_alpha to high-z Lyman-alpha emitters.
