    Expectations of the Size Evolution of Massive Galaxies at 3 ≤ z ≤ 6 from the TNG50 Simulation: The CEERS/JWST View
    We present a catalog of about 25,000 images of massive (M ⋆ ≥ 10 9 M ⊙) galaxies at redshifts 3 ≤ z ≤ 6 from the TNG50 cosmological simulation, tailored for...

    Exploring the assembly history of galaxies
    Understanding the connection between mass assembly and star-formation rate is a key question in galaxy formation. It is now well-established that a significant...

    Extremely Red Galaxies at z = 5–9 with MIRI and NIRSpec: Dusty Galaxies or Obscured Active Galactic Nuclei?
    We study a new population of extremely red objects (EROs) recently discovered by the James Webb Space Telescope (JWST) based on their NIRCam colors F277W ‑...

    Galaxies and quasars in the early Universe: recent results and future prospects from sub-millimeter observations
    In recent years, major changes were done at the IRAM Plateau de Bure interferometer and 30-meter telescope, in particular in the areas of receivers and back...

    Galaxies at high z: the MUSE revolution
    Thanks to its unique capabilities, the MUSE integral field spectrograph at ESO VLT has given us new insight of the Universe at high redshift. In this talk I...

    Galaxies Going Bananas: Inferring the 3D Geometry of High-redshift Galaxies with JWST-CEERS
    The 3D geometries of high-redshift galaxies remain poorly understood. We build a differentiable Bayesian model and use Hamiltonian Monte Carlo to efficiently...

    HerMES HFLS3: A dust-obscured massive maximum-starburst galaxy at a redshift of 6.34
    How do the first galaxies form and evolve? Optical and near-infrared deep surveys are now finding galaxies at very high redshifts. However, they are typically...
