HIRES (Phase A)
The High Resolution Spectrograph
HIRES (the High Resolution Spectrograph) is an instrument under study for ESO’s forthcoming Extremely Large Telescope (ELT). The contract to begin design studies for HIRES was signed on 22 March 2016 by ESO. The HIRES consortium is led by the Italian National Institute for Astrophysics (INAF) and composed of over 30 institutions. HIRES is currently completing the initial project stage known as Phase A.
The proposed HIRES instrument combines a high resolution and wide spectral range with the massive surface area of the ELT to produce data with very little noise or excessive signal. This will allow HIRES to study very faint astronomical objects which require highly sensitive observations.
The primary goal of HIRES would be to characterise the exoplanetary atmospheres from Neptune-like planets to Earth-like planets, with the ultimate goal of looking for signatures of life. HIRES will also allow astronomers to study the evolution of stars and galaxies; identify the signatures of the very first generation of stars in the primordial universe; and determine whether some of the fundamental constants of physics, which regulate most physical processes in the Universe, actually change with time.
The design for HIRES builds on high-resolution spectrographs made for ESO’s Very Large Telescope.
