Symposium S13  3-4 July 2024

Preparing for the first light of the Extremely Large Telescope

Aims and scope

During this symposium a status update will be given of the ESO Extremely Large Telescope (ELT) and its instrumentation. Science topics are covered for which the most dramatic advances are expected at the end of this decade when the ELT will see first light (2028). With its 39m diameter primary mirror the ELT will be the largest visible and near-infrared telescope in the world, allowing transformative science in a large variety of fields, from planetary systems to resolved stellar populations, from galaxy properties to black holes, and from fundamental physics to cosmology. The full suite of first- and second-light instruments will be presented, as well as various science cases to be addressed by these instruments. We want to inform the European astronomical community and to connect it to this European flagship project. It is time to organize the scientific community and we have to make sure that the planned instruments are capable to address the key astronomical questions building on the results obtained with the present-day and future facilities such as the VLT and Keck telescopes, Hubble Space Telescope, James Webb Space Telescope, Gaia, Euclid, and the Square Kilometer Array.

We want to:

  • Invite the European astronomical community to propose potentially interesting science cases to be addressed by the ELT and its instrumentation.
  • Discuss the expected performance and capabilities of the ELT instruments with particular attention to realistic simulations of ELT photometric and spectroscopic data.
  • Explore synergies with other facilities.


  • Status of the Extremely Large Telescope, its instrumentation, and adaptive optics (presentations by M. Cirasuolo, B. Brandl, P. Ciliegi, R. Davies, A. Marconi, R. Pello, N. Thatte)
  • The solar system and exoplanets
  • Resolved stellar populations
  • Galaxy formation and evolution
  • The high-z universe
  • The transient sky
Submission of talks/posters on science topics not already included in the above list of themes is strongly encouraged. We anticipate that the final scientific program will include balanced contributions from both junior and senior scientists.
