Scientific Rationale

This workshop is a chance to discuss the nature and evolution of high redshift galaxies, from cosmic noon to re-ionization, as derived from a variety of observational evidence collected across the whole electromagnetic spectrum, and theoretical investigations.

In the tradition of the previous meetings, we aim at bringing together members of the main extragalactic surveys and theorists to present their latest results and perspectives for the next future.

The workshop will be a chance to discuss the major questions on the ground, that will be address in specific sessions:

  • Have we reached an established census of galaxies at z>10? What is established and what is still lacking?
  • How can we constrain the physical properties of stellar populations in early galaxies? Is the spectro-photometric information and tools adequate for this goal? What are we learning about the physics of star formation and stellar feedback from observations at cosmic dawn?
  • Have we established the growth mechanism of supermassive black holes, and their role in early galaxy evolution? Can we discriminate between different avenues for black hole formation and growth, and if not how can we in the future?
  • What was the evolution of the inter-galactic medium (IGM), and how does the evolving IGM affect the observations? Are we able to track the interplay between the early evolution of galaxies and the IGM in a meaningful and self-consistent way?
  • How did metals and dust form in early galaxies, and what can we learn about galaxy formation from different abundance patterns? How well can we establish metal abundances and dust in the young Universe with existing data? Can we identify really pristine stellar populations? (PopIII)
  • Which quenching mechanisms were most effective as a function of galaxy properties, environment, and cosmic epoch. What are the key signatures of quenching on the evolving galaxy population?
  • What kind of progress in theory, simulations, and modelling is needed to interpret the observations? (move into the previous sentences)
  • Morphology – evolution of bars, compactness, abundances and early evolution of disks
  • What can we learn about ioniziation properties of galaxies across a broad redshift range z and how this affects reionization
  • What are the discoveries that we can expect from non-JWST obervations (ALMA, Euclid, Gravity)?
