    Testing fundamental physics with ESPRESSO
    Many of the most basic and important physical phenomena are determined by a set of “fundamental constants”, whose values are experimentally known to high...

    Testing the extreme acceleration mechanisms in the supermassive black holes neighborhood
    Blazars, Active Galactic Nuclei (AGN) whose relativistic jets point in the direction of the Earth, dominate the VHE (VHE, E>100 GeV) gamma-ray extragalactic sky...

    The adequacy of stellar evolution models for the interpretation of the color-magnitude diagrams of resolved stellar populations
    Work by C. Gallart, M. Zoccali y A. Aparicio has been published in the Annual Review of Astronomy and Astrophysics. The article reviews current knowledge about...

    The central molecular gas structure in LINERs with low luminosity AGN: evidence for gradual disappearance of the torus.
    We present observations of the molecular gas in the nuclear environment of three prototypical low luminosity AGN (LLAGN), based on VLT/SINFONI AO-assisted...

    The changing-look optical wind of the flaring X-ray transient Swift J1858.6-0814
    The large amount of mass and angular momentum carried by disc winds makes them key processes to understand accretion onto compact objects, such as black holes...

    The chemistry of Planetary Nebulae (PNe) and HII regions in the Local Group
    Chemical abundances have been measured of PNe and HII regions in Sex A and Sex B, two galaxies located on the outskirts of the Local Group. These PNe are the...

    The dark side of the fluffiest galaxies
    Ultra diffuse galaxies (UDGs) have the sizes of giants but the luminosities of dwarfs. A key to understanding their origins comes from their total masses, but...

    The DESIRED electron temperature relations in star-forming regions of the local Universe
    H II regions are clouds of glowing, ionised gas associated with regions of recent star formation. By studying the light emitted by these regions, we can learn...
