    Euclid: Cosmological forecasts from the void size function
    The Euclid mission - with its spectroscopic galaxy survey covering a sky area over 15 000 deg 2 in the redshift range 0.9 < z < 1.8 - will provide a sample of...

    Euclid: Early Release Observations of diffuse stellar structures and globular clusters as probes of the mass assembly of galaxies in the Dorado group
    Deep surveys have helped to unveil the history of past and present galaxy mergers, and, in particular, uncovering their tidal debris and co-located globular...
  • Publication
    Euclid: Early Release Observations – A preview of the Euclid era through a galaxy cluster magnifying lens
    We present the first analysis of the Euclid Early Release Observations (ERO) program that targets fields around two lensing clusters, Abell 2390 and Abell 2764...

    Euclid: Early Release Observations – Dwarf galaxies in the Perseus galaxy cluster
    We make use of the unprecedented depth, spatial resolution, and field of view of the Euclid Early Release Observations (EROs) of the Perseus galaxy cluster to...
  • Publication
    Euclid: Early Release Observations – Globular clusters in the Fornax galaxy cluster, from dwarf galaxies to the intracluster field
    We present an analysis of Euclid observations of a 0.6 deg 2 field in the central region of the Fornax galaxy cluster that were acquired during the performance...
  • Publication
    Euclid: Early Release Observations – Overview of the Perseus cluster and analysis of its luminosity and stellar mass functions
    The Euclid Early Release Observations (ERO) programme targeted the Perseus cluster of galaxies, gathering deep data in the central region of the cluster over 0...
