Wide range of research programmes linked to experimental and instrumental programmes at the cutting edge of astronomical technology

The wide range of research programmes carried out by the group are centred on four major areas each linked to experimental and instrumental programmes which are at the cutting edge of astronomical technology.

These activities are supported by theoretical studies, particularly in the area of fundamental physics applications in Relativity and Cosmology, as well as modelling and simulation of astronomical phenomena.

  • New constraints on the average escape fraction of Lyman continuum radiation in z~4galaxies from the VIMOS Ultra Deep Survey (VUDS) 

    Marchi, F; Pentericci, L; Guaita, L; Ribeiro, B; Castellano, M; Schaerer, D; Hathi, NP et al.
    $\textit{Context}$ 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, R (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, A 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 ...
  • Analogues of primeval galaxies two billion years after the Big Bang 

    Amorín, R; Fontana, A; Pérez-Montero, E; Castellano, M; Guaita, L; Grazian, A; Fèvre, OL et al.
    Deep observations are revealing a growing number of young galaxies in the first billion years of cosmic time. Compared to typical galaxies at later times, they show more extreme emission-line properties, higher star formation ...
