    Localized starbursts in dwarf galaxies produced by impact of low metallicity cosmic gas clouds
    Models of galaxy formation predict that gas accretion from the cosmic web is a primary driver of star formation over cosmic history. Except in very dense...

    Lyα Emitting Galaxies (LAEs) at Cosmic Dawn: Implications and Predictions
    The detection of Lyα emitting galaxies (LAEs) puts severe constraints on the reionization history. In this paper, we derive the properties of very high-z LAEs...

    Measuring a Galaxy: Morphology, Mass, Environment and Evolution
    What can the shape and size of a galaxy tell us about how it has evolved across cosmic time? Which evolutionary mechanisms are important, or relevant, and which...

    MIGHTEE-HI: Evolution of HI Scaling Relations of Star-forming Galaxies at z < 0.5
    We present the first measurements of H I galaxy scaling relations from a blind survey at z > 0.15. We perform spectral stacking of 9023 spectra of star-forming...

    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...

    NGDEEP Epoch 1: Spatially Resolved Hα Observations of Disk and Bulge Growth in Star-forming Galaxies at z ∼ 0.6–2.2 from JWST NIRISS Slitless Spectroscopy
    We study the Hα equivalent width (EW(Hα)) maps of 19 galaxies at 0.6 < z < 2.2 in the Hubble Ultra Deep Field using NIRISS slitless spectroscopy as part of the...

    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...
