Who We Are

Research Group at the University of Geneva


Welcome to the webpage of our research group: "Galaxy Build-up at Cosmic Dawn" at the University of Geneva. Our research is focused on understanding the build-up and assembly of the first generations of galaxies from a panchromatic observational study. In particular we use very deep imaging and spectroscopy from the JWST, Hubble and Spitzer Space Telescopes, in addition to ground-based follow-up with Keck, VLT, ALMA, and NOEMA. This allows us to study large samples of the galaxies and trace their mass build-up out to z~13 now, when the Universe was only approximately 300 Myr old.

A main focus of our work now will be to exploit the new JW Space Telescope, which already completely revolutionizing our view of early galaxies and for the first time provides a complete census of the galaxy population in the very early universe.

You can find a list of our team members here.
