GO-IRS stands for "GTC Optical Intermediate Resolution Spectrograph". It is the answer of a big team of over 100 experienced researchers and engineersin the United States, China and Spain to the recent call for new instrumentationfor the 10.4 m Gran Telescopio Canarias. The GO-IRS main facts are: 1000 MOS fibres in a 15 arcmin circular field of view; 4 x 400 IFU fibres in the central 2 arcmin; two channels: blue Δλ = 0.37 - 0.60 μ m) and red (Δλ = 0.60 - 1.00 μ m); R= 20k, 10k, 5k (red), 2k (blue) and intermediate spectral resolutions; and use of telescope-proof technology (e.g. LAMOST, MARVELS). The GO-IRS Science Team is developing three design reference cases on near-fieldcosmology in the Milky Way, kinematics and abundances in galaxies of the LocalGroup and of the local Universe, and astrophysical properties and clustering ofdistant galaxies at z=1-4. We open our GO-IRS Science Team to all Spanish astronomers interested in workingwith us. Visit our URL at
