Uppsala astronomers are involved in proposing the high-resolution spectrometer for the European Extremely Large Telescope (E-ELT http://www.eso.org/public/teles-instr/e-elt/). The light collecting area of this 39m telescope to be completed in 2025 is huge. We will be able to study faint and faraway objects. Spectroscopy is the way to derive temperature, density and chemical composition etc.

Thus we are working on a phase A study for in instrument covering 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 infrared arm is based on the phase A study that we performed for SIMPLE - a dedicated near infrared spectrometer for the E-ELT (http://www.hires-eelt.org/77352b_1.pdf).
