ANDES (ArmazoNes high Dispersion Echelle Spectrograph) is an instrument under study for ESO’s forthcoming Extremely Large Telescope (ELT). The contract to begin design studies for ANDES, formerly known as HIRES, was signed in 2016 by ESO. IAC is one of the more than 30 institutions in the ANDES consortium.

HARMONI is a first light optical / infrared spectrograph of integral field and high spatial resolution for ELT. Its design and construction is carried out by an international consortium in which the IAC participates together with the University of Oxford, ATC-Edinburgh, Durham University, CRAL-Lyon, LAM-Marseille, CSIC-CAB-Madrid, and the

The detection of the axion would be one of the most important events in the history of science. This hypothetical particle can simultaneously solve two fundamental questions of modern physics: the problem of violation of charge-parity (CP) symmetry in the strong interaction and the mystery of dark matter. The axion couples to photons. The search
