  • Extended ionised and clumpy gas in a normal galaxy at z=7.1 revealed by ALMA 

    Carniani, Stefano; Maiolino, Roberto; Pallottini, Andrea; Vallini, L; Pentericci, L; Ferrara, A; Castellano, M et al. (Springer Nature, 2017-09-06)
    We present new ALMA observations of the [O iii]88 μm line and high angular resolution observations of the [C ii]158 μm line in a normal star forming galaxy at z = 7.1. Previous [C ii] observations of this galaxy had detected ...
  • New constraints on the average escape fraction of Lyman continuum radiation in z ∼ 4 galaxies from the VIMOS Ultra Deep Survey (VUDS) 

    Marchi, F; Pentericci, L; Guaita, L; Ribeiro, B; Castellano, M; Schaerer, D; Hathi, NP et al. (EDP Sciences, 2017-05-01)
    $\textit{Context}$ Determining the average fraction of Lyman continuum (LyC) photons escaping high redshift galaxies is essential for understanding how reionization proceeded in the z > 6 Universe. $\textit{Aims}$ We ...
  • Using photoionization models to derive carbon and oxygen gas-phase abundances in the rest UV 

    Pérez-Montero, E; Amorín, Ricardo Oscar (Oxford University Press, 2017-01-24)
    We present a new method to derive oxygen and carbon abundances using the ultraviolet (UV) lines emitted by the gas phase ionized by massive stars. The method is based on the comparison of the nebular emission-line ratios ...
  • Planet Formation Imager (PFI): science vision and key requirements 

    Kraus, S; Monnier, JD; Ireland, MJ; Duchene, G; Espaillat, C; Honig, S; Juhasz, Attila et al. (SPIE, 2016-08-04)
    The Planet Formation Imager (PFI) project aims to provide a strong scientific vision for ground-based optical astronomy beyond the upcoming generation of Extremely Large Telescopes. We make the case that a breakthrough in ...
