A unique instrument for the biggest telescope


17-19th October 2017 – Toledo, Spain

Scientific Rationale

The Extremely Large Telescope (ELT) will be the world's largest optical/IR facility for at least a generation. It will have an immense collecting area, equivalent to gathering together all the current large telescopes in use today. Multi-object spectroscopy will be a key capability of the observatory, immediately able to harness its unprecedented sensitivity to deliver unique surveys which address a broad range of important topics in contemporary astrophysics.

The conceptual design of MOSAIC, a powerful multi-object spectrograph for the ELT, will conclude in late 2017. The design combines high-multiplex near-IR and visible spectroscopy, together with AO-corrected spectroscopy in the near-IR that exploits the fantastic angular resolution of the ELT across a large field of view. These capabilities will enable MOSAIC to tackle fundamental questions, e.g. pertaining to the formation and evolution of galaxies, which are simply out of reach of other facilities.

This colloquium is timed to discuss the scientific opportunities of surveys with MOSAIC, focussing in particular on simulated performances from the conceptual design. It will also take stock of other developments that will influence surveys envisaged for the late 2020s.
