The formation of the first galaxies in the Universe is the new frontier of both galaxy formation and reionization studies. In fact, we will soon directly observe primeval galaxies thanks to the James Webb Space Telescope, and witness the reionization process through 21cm intensity mapping experiments. This unique moment in human history creates a

El Telescopio Solar Europeo espera alcanzar el diseño preliminar de todo el telescopio en 2023. Algunos subsistemas han pasado la Revisión de Diseño Preliminar (PDR) como es el caso de la Estructura del Telescopio, la Cubierta y Pilar, subsistemas en los que se centrará este seminario repasando su estado actual y sus prestaciones principales, así

Algunas palabras pueden ser seductoras y llegar a impulsar grandes hazañas, o pueden herir y, por despecho, motivar enormes esfuerzos, mover personas y sus creencias y con ellas arrastrar a las naciones. Un grupo de hombres, motivados por estas palabras, se enfrentaron a sus circunstancias y cruzaron las fronteras del mundo conocido, transformando

Vimos Public Extragalactic Redshift Survey (VIPERS) is a spectroscopic survey designed to investigate the spatial distribution of ~90k galaxies on redshift 0.4<z<1.2. The catalogue of spectroscopic observations, combined with auxiliary photometric data, is perfect for evolutionary studies of different types of galaxies. But also for tracing rare

The tidal tails of stellar clusters are an important tool for studying the clusters’ birth conditions, their evolution, coupling, and interaction with the Galactic potential, and to understand how field stars populate the Milky Way. Thanks to Gaia, much progress has been accomplished in finding tails of open clusters. We will show here that the

After placing the Gaia mission in the context of current astrophysical research, the astrometric, photometric, and spectroscopic data provided by the satellite, as presented in its third data archive, DR3, will be reviewed. Gaia third archive contains, in addition to the measurements from the satellite's instruments, an extensive set of
