Descripción
We present the results of our search near the end of the Reionization Epoch for faint galaxies around two close, massive Lyman-α emitters (LAEs) at redshift 6.5, discovered in the SXDS field, using very deep OSIRIS images and spectroscopy obtained at the Gran Telescopio Canarias (GTC). The luminosity function of these LAEs shows that this area is about 1.5 times denser than the general field galaxy population at z = 6.5. Our results implies the discovery of one of the earliest protoclusters in the Universe, which will evolve to resemble the most massive galaxy clusters today.

    ANDES, the high-resolution spectrograph for the ELT: design of the adaptive optics system
    ANDES,the high resolution spectrograph for the ELT, will work both in seeing limited mode and with Adaptive Optics (AO) correction. ANDES-SCAO is a single conjugated AO system working with natural guide stars, feeding the IFU coupled to the YJH spectrograph. The main science goal of the ANDES AO mode is the characterization of the exo-planet

    HARMONI at ELT: verification tests of opto-mechanical mounts for HARMONI preoptics in cryogenic environment
    HARMONI is the high angular optical and near-IR integral field spectrograph (IFS) for the ELT. The instrument covers a large spectral range from 470 to 2450nm with resolving powers from 3300 to 18000 and spatial sampling from 60 to 4mas. A workhorse instrument designed to operate in two Adaptive Optics modes - Single-Conjugate Adaptive Optics (SCAO
