The forthcoming generation of Extremely Large Telescope (ELTs) will reach unprecedented spectroscopic sensitivity coupled with high angular resolution in the near infrared. This workshop will bring together the international astronomical community to explore the transformational science that the spectroscopic instrument suites of the ELTs (GMT, TMT and ELT) will achieve. High resolution simulations have played a key role in the development of the instrument science cases providing a quantifiable means to determine feasibility and to predict the scientific outcomes that can be achieved. By bringing together theoreticians, modelers and observers, with interests ranging from exoplanets to cosmology, the goals of the workshop are to:  

  • explore the spectroscopic capabilities of the first‐light instrument suite of the ELTs identifying synergies and complementarities between them  

  • encourage development of ELT science cases including preparatory projects on existing telescopes 

  • provide hands‐on experience using the HARMONI simulator (H-SIM) 

  • encouraging collaboration and transfer of expertise between the instrument teams and the wider community

  • explore synergies with other facilities 

The meeting will set the stage for the community to plan and coordinate ELT science programmes and pre-cursor observations, making use of quantitative estimates of what the ELTs can achieve. 

The programme will feature invited and contributed presentations on instruments, simulations and a wide range of science cases covering

  • Early Universe and Cosmology
  • Galaxy Evolution and Resolved Galaxies
  • Resolved Stellar Populations
  • Star Formation and Evolution
  • Black Holes/AGN near and far
  • Transient Universe
  • Extrasolar planets
  • Solar System
