  • The GTC facility instruments: a status review
    The Gran Telescopio Canarias (GTC) 10.4m telescope received its First Light on July 13, 2007. At present the GTC is undergoing commissioning tests. Night time observations are being carried out routinely from Monday through to Thursday every week. The GTC will begin science observation by the end of the year, and will be offered to the community in

  • The GTC main axes servos and control system
    The GTC azimuth and elevation axes control systems employ large custom direct-drive motors operated by means of embedded fully-digital current loops. A high-performance position loop has been developed based on sinusoidal encoder feedback with interpolation error compensation. Real-time servo feedback and trajectory tracking is implemented by

  • The GTC primary mirror control system
    The Gran Telescopio Canarias (GTC) primary mirror control system is responsible for making the 36 segments behave like a monolithic mirror. It deals with 108 positioners giving 3 degrees of freedom to each segment, 168 position sensors installed between adjacent segments measuring nanometrical displacements, 216 actuators controling the figure of

  • The GTC project: under commissioning
    The GTC (Gran Telescopio Canarias) is an optical/IR telescope, with a 10,4 meter segmented primary, installed at the Observatorio del Roque de Los Muchachos (ORM), at La Palma. Past July 2007 it saw its First Light showing a very promising behaviour. The very good image quality achieved at that an early stage of telescope commissioning is a direct

  • The halo+cluster system of the Galactic globular cluster NGC 1851
    NGC 1851 is surrounded by a stellar component that extends more than 10 times beyond the tidal radius. Although the nature of this stellar structure is not known, it has been suggested to be a sparse halo of stars or associated with a stellar stream. We analyse the nature of this intriguing stellar component surrounding NGC 1851 by investigating

  • The Herschel Multi-tiered Extragalactic Survey: HerMES
    The Herschel Multi-tiered Extragalactic Survey (HerMES) is a legacy programme designed to map a set of nested fields totalling ˜380 deg2. Fields range in size from 0.01 to ˜20 deg2, using the Herschel-Spectral and Photometric Imaging Receiver (SPIRE) (at 250, 350 and 500 μm) and the Herschel-Photodetector Array Camera and Spectrometer (PACS) (at
