    • Chronos: A NIR spectroscopic galaxy survey to probe the most fundamental stages of galaxy evolution 

      Ferreras, I.; Cropper, M.; Sharples, R.; Bland-Hawthorn, J.; Bruzual, G.; Charlot, S.; Conselice, C. J.; Driver, S.; Dunlop, J.; Hopkins, A. M.; Kaviraj, S.; Kitching, T.; Barbera, F. La; Lahav, O.; Pasquali, A.; Serjeant, S.; Silk, J.; Windhorst, R. (2021-07-18)
      We propose a dedicated, ultra-deep spectroscopic survey in the near infrared (NIR), that will target a mass-limited sample of galaxies during two of the most fundamental epochs of cosmic evolution: the formation of the ...

    • Exploring the formation of spheroidal galaxies out to z ∼ 1.5 in GOODS 

      Ferreras, I.; Lisker, T.; Pasquali, A.; Kaviraj, S. (2009-05-01)
      The formation of massive spheroidal galaxies is studied on a visually classified sample extracted from the Advanced Camera for Surveys/Hubble Space Telescope (ACS/HST) images of the Great Observatories Origins Deep Survey ...

    • Is the IMF in ellipticals bottom-heavy? Clues from their chemical abundances 

      Masi, C. De; Vincenzo, F.; Matteucci, F.; Rosani, G.; Barbera, La; Pasquali, A.; Spitoni, E. (2019-02)
      We tested the implementation of different initial mass functions (IMFs) in our model for the chemical evolution of ellipticals, with the aim of reproducing the observed relations of [Fe/H] and [Mg/Fe] abundances with galaxy ...

    • On the formation of massive galaxies : A simultaneous study of number density, size and intrinsic colour evolution in GOODS 

      Ferreras, I.; Lisker, T.; Pasquali, A.; Khochfar, S.; Kaviraj, S. (2009-07-01)
      The evolution of number density, size and intrinsic colour is determined for a volume-limited sample of visually classified early-type galaxies selected from the Hubble Space Telescope/Advanced Camera for Surveys images ...

    • The role of environment on the formation of early-type galaxies 

      Rogers, B.; Ferreras, I.; Kaviraj, S.; Pasquali, A.; Bernardi, M.; Lahav, O. (2010-06-01)
      The effect of environment on galaxy formation poses one of the best constraints on the interplay between mass assembly and star formation in galaxies. We present here a detailed study of the stellar populations of a ...

    • Star formation and nuclear activity in close pairs of early-type galaxies 

      Rogers, B.; Ferreras, I.; Kaviraj, S.; Pasquali, A.; Sarzi, M. (2009-11-01)
      We extract from the Sloan Digital Sky Survey a sample of 347 systems involving early-type galaxies separated by less than 30 kpc, in projection, and 500 km s−1 in radial velocity. These close pairs are likely progenitors ...
