    Simulating cosmic reionization
    The first galaxies are thought to have started the reionization of the Universe, that is the transformation of the cosmic hydrogen from its initial neutral to...

    Spitzer Catalog of Herschel-selected Ultrared Dusty Star-forming Galaxies
    The largest Herschel extragalactic surveys, H-ATLAS and HerMES, have selected a sample of “ultrared” dusty star-forming galaxies (DSFGs) with rising SPIRE flux...

    Star formation on kpc-scales from redshift 0.1 to 1.5
    Morphologies of star-forming galaxies at z>1 are typically irregular containing a handful of dominant bright regions. Recent observational evidence suggest that...

    Stellar haloes of disc galaxies at z~1
    Taking advantage of the ultra-deep near-infrared imaging obtained with the Hubble Space Telescope on the Hubble Ultra Deep Field, we detect and explore for the...

    Studying galaxies at low and high redshifts with GRBs
    Long gamma-ray bursts are supposed to be connected to the death of very massive stars. Due to their brightness, we can detect them to much larger distances than...

    Tests for the Expansion of the Universe
    Almost all cosmologists accept nowadays that the redshift of the galaxies is due to the expansion of the Universe (cosmological redshift), plus some Doppler...
