    The enrichment history of cosmic metals
    We use a suite of cosmological, hydrodynamical simulations to investigate the chemical enrichment history of the Universe. Specifically, we trace the origin of...

    The filling factor of intergalactic metals at redshift z= 3
    Observations of quasar absorption-line systems reveal that the z= 3 intergalactic medium (IGM) is polluted by heavy elements down to H I optical depths τH I≪ 10...

    The First Billion Years project: the impact of stellar radiation on the co-evolution of Populations II and III
    With the first metal enrichment by Population III (Pop III) supernovae (SNe), the formation of the first metal-enriched, Pop II stars becomes possible. In turn...

    The galaxy-halo connection in the cosmic web
    Galaxies and the dark matter halos in which they reside are intrinsically connected. That relationship holds information about key processes in galaxy and...

    The impact of different physical processes on the statistics of Lyman-limit and damped Lyman α absorbers
    We compute the z = 3 neutral hydrogen column density distribution function f(NHI) for 19 simulations drawn from the Overwhelmingly Large Simulations project...

    The Lyman-α forest catalogue from the Dark Energy Spectroscopic Instrument Early Data Release
    We present and validate the catalogue of Lyman-α forest fluctuations for 3D analyses using the Early Data Release (EDR) from the Dark Energy Spectroscopic...

    The Milky Way as you never saw it before
    Abstract: The study of the structure of our Galaxy, particularly its inner disc, has always been hindered by two factors: interstellar extinction dims even the...

    The multiple routes of galaxy transformation across the cosmic epochs
    In the local universe most of the stellar mass is in passive galaxies, where star formation isabsent or at very low levels. Understanding what are the...

    The Origin of the Relation between Metallicity and Size in Star-forming Galaxies
    For the same stellar mass, physically smaller star-forming galaxies are also metal richer. What causes the relation remains unclear. The central star-forming...
