Descripción
Line profiles in ensuremath {{H}alpha } emission from H II region populations in spiral galaxies show emission features at +/-50 km/s from the main emission peaks of a significant fraction of regions, which are characteristic of expanding shells. We interpret these in two possible scenarios: mass-loaded wind outflows from the central OB stars, or dust-coupled, radiation-driven outflows, caused by the same objects.

    Conceptual design of the infrared integral field spectropolarimeter for the European Solar Telescope
    The European Solar Telescope (EST) will be Europe's most ambitious ground-based infrastructure in solar physics. It will have a primary mirror with a diameter of 4.2m, which will make it the largest in Europe, and of identical aperture as the largest solar telescope available worldwide, namely the Daniel K. Inouye Telescope (DKIST) installed at the

    Detector upgrade in EMIR@GTC: on-sky performances
    EMIR was shipped to the GTC on May 2016 and had its first light on June 2016. Since the beginning, the EMIR performances have been severely hampered by the many instabilities in the infrared detector, a 2048x2048 Hawaii2, built with the old original technology of the Teledyne Hawaii series. Despite of this, the instrument has proven to be powerful

    The Large Interferometer For Exoplanets (LIFE): a space mission for mid-infrared nulling interferometry
    The Large Interferometer For Exoplanets (LIFE) is a proposed space mission that enables the spectral characterization of the thermal emission of exoplanets in the solar neighborhood. The mission is designed to search for global atmospheric biosignatures on dozens of temperate terrestrial exoplanets and it will naturally investigate the diversity of
