Descripción
We give a progress report on the activities within the CIFIST Team
related to the search for extremely metal-poor (EMP) stars in the Sloan
Digital Sky Survey's (SDSS) spectroscopic catalogue. So far, the search
has provided 25 candidates with metallicities around or smaller than -3.
For 15 candidates, high-resolution spectroscopy with UVES at the VLT has
confirmed their EMP status. Work is under way to extend the search to
the SDSS's photometric catalogue by augmenting the SDSS photometry and
by gauging the capabilities of X-shooter when going to significantly
fainter targets.
