    Non-instantaneous gas recycling and chemical evolution in N-body disk galaxies
    After briefly recalling basic facts about the metallicity gradients inspiral galaxies, we summarize two recent N-body gas-dynamical modelsthat implement a non...

    OMAIRA GONZÁLEZ MARTÍN: “Los Observatorios en Canarias han sido clave para avanzar en el estudio de la actividad nuclear en galaxias”
    Para los astrónomos, uno de los mayores obstáculos es la oscuridad propia del Universo, especialmente, la que genera el gas y el polvo que ensombrece objetos...

    On the extreme properties of massive galaxies at high redshifts
    Massive (&#8805 10 11 M⊙) galaxies at high redshift (z &#8805 1.5) remain mysterious objects. Their extremely small sizes (effective radii of 1-2 kpc) make them...

    On the Nature of Disks at High Redshift Seen by JWST/CEERS with Contrastive Learning and Cosmological Simulations
    Visual inspections of the first optical rest-frame images from JWST have indicated a surprisingly high fraction of disk galaxies at high redshifts. Here, we...

    Photometric Signature of Ultraharmonic Resonances in Barred Galaxies
    Bars may induce morphological features, such as rings, through their resonances. Previous studies suggested that the presence of "dark gaps," or regions of a...

    Planning the WHT future: the WEAVE wide-field massive-multiplex spectrograph
    The vision for the use of the WHT in the coming decade is taking shape. A key element is the construction and deployment of WEAVE, a wide-field massive...

    Probing the early Universe with radio galaxies
    Luminous high-redshift radio galaxies (HzRGs) are associated with the most massive known galaxies in the early Universe. These galaxies have the properties...
