Descripción
In these proceedings we give a summary of the characteristics and
current status of the MEGARA instrument, the future optical IFU and MOS
for the 10.4-m Gran Telescopio Canarias (GTC). MEGARA is being built by
a Consortium of public research institutions led by the Universidad
Complutense de Madrid (UCM, Spain) that also includes INAOE (Mexico),
IAA-CSIC (Spain) and UPM (Spain). The MEGARA IFU includes two different
fiber bundles, one called LCB (Large Compact Bundle) with a
field-of-view of 12.5×11.3 arcsec2 and a spaxel size of
0.62 arcsec yielding spectral resolutions between R=6,800-17,000 and
another one called SCB (Small Compact Bundle) covering 8.5×6.7
arcsec2 with hexagonally-shaped and packed 0.42-arcsec
spaxels and resolutions R=8,000-20,000. The MOS component allows
observing up to 100 targets in 3.5×3.5 arcmin2. Both
the IFU bundles and the set of 100 robotic positioners of the MOS will
be placed at one of the GTC Folded-Cass foci while the spectrographs
(one in the case of the MEGARA-Basic concept) will be placed at the
Nasmyth platform. On March 2012 MEGARA passed the Preliminary Design
Review and its first light is expected to take place at the end of 2015.
