    Nature of High Equivalent Width Emitters in the Epoch of Reionization Revealed by JWST Medium-band Imaging
    Extreme emission line galaxies (EELGs) at high redshifts are considered key contributors to cosmic reionization at z > 6 due to their higher ionization...

    Negative feedback in the most powerful active galaxies - NO STREAMING -
    Evidence for an intimate connection between supermassive black hole (SMBH) growth and the evolution of galaxies is nowadays compelling. Not only have SMBHs been...

    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: “The Canary Observatories have been essential in the advance of the study of nuclear activity in galaxies”
    For astronomers one of the biggest obstacles is the darkness of the Universe itself, above all the darkness caused by the gas and dust which surround active...

    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...
