HORuS: the new high-resolution spectrograph for the GTC 

20/12/2018
GTC has a new panchromatic instrument -- a high resolution spectrograph. The High Optical Resolution Spectrograph, HORuS,  has finished the commissioning tests and will become available to the astronomical comunity in 2019.  HORuS is mainly a recycled instrument, with most of its components coming from the UES spectrograph, which was in operation on the William Herschel Telescope in the 90's. After some modifications, an upgrade in the cross-dispersion prisms, and a new detector, HORuS is now coupled with optical fibers to the largest optical and infrared telescope in the world, using a robotic aquisition arm inside OSIRIS, the first-generation GTC instrument. In Egyptial mythology Horus was the son of OSIRIS. This video shows the tests at the IAC Headquarters, and the instrument assembly and first results at the telescope.
