Título: MEGARA: a new generation optical spectrograph for GTC

Resumen: The status of the MEGARA project (Multi-Espectrógrafo en GTC de Alta Resolución para Astronomía), the future optical Integral-Field Unit (IFU) and Multi-Object Spectrograph (MOS) for the GTC 10.4m, will be presented.

MEGARA offers two IFU fiber bundles, one covering 12.5x11.3 arcsec2 with a spaxel size of 0.62 arcsec (LCB) and another one covering 8.5x6.7 arcsec2 with a spaxel size of 0.42 arcsec (SCB). The MEGARA MOS mode will allow observing up to 100 objects in a region of 3.5x3.5 arcmin2 around the two IFU bundles. Both the LCB IFU and MOS capabilities of MEGARA will provide intermediate-to-high spectral resolutions (R~6,000, 12,000 and 18,700, respectively for the low-, mid- and high-resolution VPH gratings). These values become R~7,000, 13,500, and 21,500 when the SCB is used.

The UCM (Spain) leads the MEGARA Consortium that also includes INAOE (Mexico), IAA-CSIC (Spain), and UPM (Spain). MEGARA is being developed under a contract between GRANTECAN and UCM. The detailed design, construction and AIV phases are now funded and the instrument should be delivered to GTC before the end of 2016.
