    Gas expulsion by quasar-driven winds as a solution to the overcooling problem in galaxy groups and clusters
    Galaxy groups are not scaled down versions of massive galaxy clusters - the hot gas in groups [known as the intragroup medium (IGrM)] is, on average, less dense...

    Giant galaxy growing from recycled gas: ALMA maps the circumgalactic molecular medium of the Spiderweb in [C I]
    The circumgalactic medium (CGM) of the massive Spiderweb Galaxy, a conglomerate of merging proto-cluster galaxies at z = 2.2, forms an enriched interface where...

    High-velocity clouds as dark matter in the Local Group
    The High-Velocity Clouds (HVCs) observed in the Galactic neighbourhood, have been proposed to be remnants of the formation of the galaxies in the Local Group...

    History of the gas fuelling star formation in EAGLE galaxies
    Theory predicts that cosmological gas accretion plays a fundamental role fuelling star formation in galaxies. However, a detailed description of the accretion...

    Internal dynamics of the massive cluster Abell 697: a multiwavelength analysis
    Aims.We conduct an intensive study of the rich, X-ray luminous, and hot galaxy cluster Abell 697 (at z=0.282), likely containing a diffuse radio-emission, to...

    Internal dynamics of the radio-halo cluster A2219: A multi-wavelength analysis
    We present the results of the dynamical analysis of the rich, hot, and X-ray very luminous galaxy cluster A2219, containing a powerful diffuse radio-halo. Our...

    JWST view of Polycyclic Aromatic Hydrocarbons and dust in local active galaxies
    Nowadays, it is widely accepted that most galaxies undergo an active phase in their evolution. The impact of the energy released by active galactic nuclei (AGN)...

    Kinematics of Extremely Metal-poor Galaxies: Evidence for Stellar Feedback
    The extremely metal-poor (XMP) galaxies analyzed in a previous paper have large star-forming regions with a metallicity lower than the rest of the galaxy. Such...

    Localized Starbursts in Dwarf Galaxies Produced by the 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...
