Descripción
We are presenting new empirical fitting functions for the Lick/IDS line-strength indices as measured in MILES (Medium-resolution INT Library of Empirical Spectra). Following previous work in the field, these functions describe the empirical behaviour of the line-strength indices with the atmospheric stellar parameters (T eff, logg, [Fe/H]). In order to derive the fitting functions we have devised a new procedure which, being fully automatic, provides a better description of the line-strength index variations in the stellar parameter space.

    European Solar Telescope expected performance
    The European Solar Telescope (EST) will be the biggest solar telescope in Europe and it is currently concluding its preliminary design that includes adaptive optics from its first light. In this phase of the project, the feasibility of the project is demonstrated and the design must meet the requirements after having mitigated the major risks. The

    A multi-wavelength view of AGN feedback in the central kiloparsecs of quasar host galaxies
    Active galactic nuclei (AGN) winds and jets are potential drivers of multi-phase outflows and can significantly modify the interstellar medium (ISM) properties of their host galaxies. The Quasar Feedback (QSOFEED) project aims to investigate the impact of multi-phase quasar-driven outflows and jets on the nuclear regions of quasar host galaxies

    The Undiscovered Ultra Diffuse galaxies of the Local Group: predictions from constrained cosmological simulations
    Ultra-diffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are difficult to detect because of their low surface brightness. In the Local Group a handful of UDGs have been found to date, most of which are satellites of the Milky Way and M31, and only two are
