Digging deep into the extragalactic infrared sky

Over the last years, IR Extragalactic Astronomy has made rapid progress thanks to major survey efforts carried out with ground-based and space observatories. These studies are preparing the ground for the science to be tackled with the next generation of IR telescopes, in particular the James Webb Space Telescope (JWST). This two-day symposium will bring the IR Extragalactic Astronomy community together to present some of the most salient observational and theoretical results of galaxy evolution of the last years. A significant part of this symposium will be devoted to present and discuss the new science that will be enabled by the unprecedented sensitivity and angular resolution of the JWST at near-/mid-IR wavelengths.



  • Galaxy Assembly and Evolution: star formation and stellar mass assembly over cosmic times; evolution of galaxy structural parameters; chemical enrichment; galaxy evolution within cosmological models.
  • Dust-Obscured Star Formation in Galaxies at Different Cosmic Times: dust-obscured star formation at different redshifts; PAHs as star-formation tracers; dust-obscured activity in galaxy formation models.
  • AGN at IR Wavelengths: The unification model revisited; the origin of the IR emission in low-luminosity AGN; dust-obscured black-hole growth and the starburst/AGN connection.
  • Galaxies in the Young Universe: galaxy properties and AGN activity at z>6; the sources of hydrogen reionisation; dust production in the early Universe; early chemical enrichment of galaxies and the intergalactic medium.
  • Scientific Prospects for the JWST I: galaxy evolution studies in the near-IR (NIRSpec/NIRCam); the physics of galaxies studied with JWST’s high spatial resolution spectroscopy; the complementarity between JWST instruments for different science cases.
  • Scientific Prospects for the JWST II: galaxy evolution studies with MIRI. Synergies between the JWST and other simultaneously-operating observatories that are relevant for the European astronomical community (ALMA, VLT, E-ELT, SKA, SPICA, etc.).
