We present a measurement of the Type I quasar luminosity function at z = 5 using a large sample of spectroscopically confirmed quasars selected from optical imaging data. We measure the bright end (M 1450

We present a general overview and the first results of the SUMO project (a SUrvey of Multiple pOpulations in Globular Clusters). The objective of this survey is the study of multiple stellar populations in the largest sample of globular clusters homogeneously analysed to date. To this aim we obtained high signal-to-noise (S/N > 50) photometry for

The aim of this short contribution is to inform the Spanish Society of Astronomy about the theoretical background and scientific motivation for the Chromospheric Lyman-alpha Spectropolarimeter (CLASP), whose goal is to open up a diagnostic window for magnetic field measurements in the outer solar atmosphere. CLASP is an experiment for measuring the

CanariCam is a mid-IR camera and spectrograph with coronographic and polarimetric capabilities, built by the University of Florida to operate at the GTC. CanariCam is designed to work at the diffraction limit of the GTC at 8 μm. To reach the required image quality and sensitivity, the operation must be carried out under stringent atmospheric

The OTELO Project is an extragalactic survey under way using the tunable filters of the instrument OSIRIS at the GTC. OTELO is already providing the deepest emission line survey of the universe up to a redshift 7. In this contribution, the status of the survey and the first preliminary results obtained will be presented.

LINERs have been a class of low-luminosity AGN difficult to explain under the unified model. It has been claimed (González-Martín et al. 2009b) that a high percentage of them are obscured sources. Mid-infrared high spatial resolution data will bring us the oportunity to study the obscuration of these intringuing sources. However, these observations
