    Time variation of the fine structure constant in the early universe and the Bekenstein model
    Aims:We calculate the bounds on the variation in the fine structure constant at the time of primordial nucleosynthesis and at the time of neutral hydrogen...

    Tracing the cosmic web
    The cosmic web is one of the most striking features of the distribution of galaxies and dark matter on the largest scales in the Universe. It is composed of...

    Tracing the Evolution of Dust Obscured Star Formation and Accretion Back to the Reionisation Epoch with SPICA
    Our current knowledge of star formation and accretion luminosity at high redshift (z > 3-4), as well as the possible connections between them, relies mostly on...

    Tracking the impact of environment on the galaxy stellar mass function up to z ~ 1 in the 10 k zCOSMOS sample
    We study the impact of the environment on the evolution of galaxies in the zCOSMOS 10 k sample in the redshift range 0.1 ≤ z ≤ 1.0 over an area of ~1.5 deg2...

    Ubiquitous seeding of supermassive black holes by direct collapse
    We study for the first time the environment of massive black hole (BH) seeds (˜104-5 M⊙) formed via the direct collapse of pristine gas clouds in massive haloes...

    Understanding the Cosmic Mass Function High-Mass Behavior
    We claim that the discrepancy found between the theoretical predictions for the cosmic mass function and those found in numerical simulations is due to the fact...
  • Publication
    Understanding the history of obscured star formation in the high-redshift with coordinated GTC and LMT surveys
    The advances in bolometric detector technology during the last 15 years have allowed (sub)millimetre wavelength measurements to contribute important data to...
