The GTC is a high performance 10-m class telescope to be installed at the Roque de los Muchachos Observatory (ORM), on the island of La Palma. First light is...

We are conducting a multi-wavelength (radio, optical, and X-ray) observational campaign to classify, morphologically and physically, a sample of 55 flat...

Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range ≈ 10-60 GHz. AME was first detected in 1996...

Since the early 1970s, stellar population modelling has been one of the basic tools for understanding the physics of unresolved systems from observation of...

Using a large amount of data gathered during previous seeing campaign at ORM, we analyse the temporal evolution of seeing in order to find out whether...

It is planned to include adaptive optics as an integral part of the 10-m Gran Telescopio Canarias. Preliminary scientific requirements have been drawn up, and...

The COMPTEL observations of the galactic 1.809 MeV emission attributed to the radioactive decay of 26Al have confirmed the diffuse nature of this interstellar...
