  • Kiloparsec-scale gaseous clumps and star formation at z = 5–7 

    Carniani, Stefano; Maiolino, Roberto; Amorin Barbieri, Ricardo; Pentericci, Laura; Pallottini, Andrea; Ferrara, Andrea; Willott, Chris et al.
    We investigate the morphology of the [Cii] emission in a sample of “normal” star-forming galaxies at 5 < z < 7:2 in relation to their UV (rest-frame) counterpart. We use new ALMA observations of galaxies at z 6 7, as ...

  • Extended and broad Ly α emission around a BAL quasar at z ∼ 5 

    Ginolfi, Michele; Maiolino, Roberto; Carniani, Stefano; Battaia, Fabrizio Arrigoni; Cantalupo, Sebastiano; Schneider, Raffaella
    In this work we report deep MUSE observations of a broad absorption line (BAL) quasar at z ∼ 5, revealing a Ly α nebula with a maximum projected linear size of ∼60 kpc around the quasar (down to our 2σ SB limit per layer ...

  • Characterization of star-forming dwarf galaxies at 0.1 ≲ z ≲ 0.9 in VUDS: Probing the low-mass end of the mass-metallicity relation 

    Calabrò, A; Amorin Barbieri, Ricardo; Fontana, A; Pérez-Montero, E; Lemaux, BC; Ribeiro, B; Bardelli, S et al. (2017-05-01)
    © 2017 ESO. Context. The study of statistically significant samples of star-forming dwarf galaxies (SFDGs) at different cosmic epochs is essential for the detailed understanding of galaxy assembly and chemical evolution. ...

  • The supermassive black hole coincident with the luminous transient ASASSN-15lh 

    Krühler, T; Fraser, M; Leloudas, G; Schulze, S; Stone, NC; Van Velzen, S; Amorin Barbieri, Ricardo et al. (EDP Sciences, 2018-04-01)
    The progenitors of astronomical transients are linked to a specific stellar population and galactic environment, and observing their host galaxies hence constrains the physical nature of the transient itself. Here, we use ...
