Entre las áreas hacia donde ha evolucionado la Química en los últimos años están los estudios de sistemas con especies reactivas de alta energía y los dominados por fuerzas intermoleculares débiles, con energías de unas pocas kcal/mol. En efecto, el estudio de las propiedades de los iones, comenzando por su relación con la molécula neutra de la que

OTELO (OSIRIS Tunable Emission Line Object Survey) is the GTC Key Project that will allow an optimal exploitation of the Spanish Day One GTC instrument OSIRIS with a high scientific output and international impact. The survey will be made using tunable filters, a unique feature of OSIRIS in 8-10 m telescopes, to do co-mobile tomography at a depth

OSIRIS (Optical System for Imaging and low Resolution Integrated Spectroscopy) is the optical Day One instrument for the GTC and the only Spanish Day One instrument. With both instrument and telescope schedules matched, OSIRIS will be available as soon as the GTC is scientifically operational. In this contribution an overview of the instrument

The Real Instituto y Observatorio de la Armada (ROA) meridian circle was moved to the Estación de Altura Carlos Ulrrico Cesco in the República Argentina in 1996. Until November 1999 the observations were carried out with a moving slit micrometer. In spring 2001 the result of these observations has been published, forming the first Hispano

I will review some results of observational cosmology which critically cast doubt upon the foundations of the standard cosmology: 1) The redshifts of the galaxies are due to the expansion of the Universe; 2) The cosmic microwave background radiation and its anisotropies come from the high energy primordial Universe; 3) The abundance pattern of the
