    The First Billion Years project: gamma-ray bursts at z > 5
    Long gamma-ray burst's (LGRB's) association with the death of massive stars suggests that they could be used to probe the cosmic star formation history (CSFH)...

    The First Billion Years project: proto-galaxies reionizing the Universe
    The contribution of stars in galaxies to cosmic reionization depends on the star formation history in the Universe, the abundance of galaxies during...

    The First Billion Years project: the escape fraction of ionizing photons in the epoch of reionization
    Protogalaxies forming in low-mass dark matter haloes are thought to provide the majority of ionizing photons needed to reionize the Universe, due to their high...

    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 First Billion Years simulation project. Galactic outflows and metal enrichment
    The First Billion Years is one of the largest and most comprehensive cosmological, hydrodynamical simulation of the early Universe to date. It studies the...

    The first Frontier Fields cluster: 4.5 μm excess in a z ~ 8 galaxy candidate in Abell 2744
    Aims: We present in this letter the first analysis of a z ~ 8 galaxy candidate found in the Hubble and Spitzer imaging data of Abell 2744 as part of the Hubble...

    The first Herschel view of the mass-SFR link in high-z galaxies
    Aims: We exploit deep observations of the GOODS-N field taken with PACS, the Photodetector Array Camera and Spectrometer, onboard of Herschel, as part of the...

    The First Precise Determination of an Optical-Far-Ultraviolet Extinction Curve Beyond the Local Group (z=0.83)
    We present the optical-far-ultraviolet extinction curve of the dust in the lens galaxy of the gravitational lens system SBS 0909+532 (z=0.83). Extending our...

    The first sample of spectroscopically confirmed ultra-compact massive galaxies in the Kilo Degree Survey
    We present results from an ongoing investigation using the Kilo Degree Survey (KiDS) on the VLT Survey Telescope (VST) to provide a census of ultra-compact...
