Uppsala astronomers are involved in proposing the high-resolution spectrometer for the European Extremely Large Telescope (E-ELT). The light collecting area of this 39 m telescope to be completed in 2025 is huge. Science operations are planned to start in 2027. We will be able to study faint and faraway objects. Spectroscopy is the way to derive temperature, density and chemical composition etc.
In 2020, the instrument consortium completed a phase A study, showing the feasibility of designing and building an instrument that covers a spectral range from 0.4 to 1.5 micron with spectral resolution of 3 km/s. The instrument will consist of a few specialized arms optimized for parts of the spectrum.
The consortium is currently awaiting approval from ESO council to proceed with the next phase in this project. See also https://elt.eso.org/instrument/HIRES/
