Descripción
A survey of 380 sq. deg. of the sky with the 1m Schmidt telescope at the Observatorio Nacional de Llano del Halo and the QUEST camera has found 498 RR Lyrae variables lying from 4 to 60 kpc from the Sun. We describe the halo substructure revealed by these data and the results of measuring some of the stars' radial velocities and metal abundances.

    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

    Contrast optimization in wide-field AO
    In Solar Adaptive Optics (AO), it is common to work with a wide Field of View (FoV), which necessitates special control techniques to enhance system performance. Ground-Layer Adaptive Optics (GLAO) configurations lack sufficient degrees of freedom to correct altitude layers individually, resulting in an averaged correction across the entire FoV. In
