EMIR (Infrared Multiobject Spectrograph) is a wide-field, near-infrared, multi-object spectrograph proposed for the Nasmyth focus of GTC. It will allow observers to obtain from tens to hundreds of intermediate resolution spectra simultaneously, in the nIR bands Z, J, H, K. A multi-slit mask unit will be used for target acquisition.
During March 2009 the EMIR optical bench, a critical component of the instrument, has been successfully integrated by the IAC technicians at the IAC instrumentation clean room. This is indeed a major step towards the completion of EMIR, expected to be ready during the first semester of 2011.
EMIR addresses the core observing goals of a 10-m class telescope by providing multi-object near-IR spectroscopy of faint sources. Typical targets will be faint galaxies, low-mass stars, brown dwarfs, distant supernovae, stellar populations in resolved external galaxies, HII regions and objects in dust obscured regions: galactic nuclei, young stellar objects and edge-on galaxies.
