    • 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. (Oxford University Press, 2018-07)
      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 (Oxford University Press, 2018-05)
      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. (EDP Sciences, 2017-05)
      We present the discovery and spectrophotometric characterization of a large sample of 164 faint ($i_{AB}$ $\sim$ $23$-$25$ mag) star-forming dwarf galaxies (SFDGs) at redshift $0.13$ $\leq z \leq$ $0.88$ selected by the ...
    • 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 ...
