The Instituto de Astrofisica de Canarias (IAC) is undertaking the construction of an IR camera for astronomical use at the 1.5 meter (f/13,8) Carlos Sanchez IR Telescope (CST), sited at the Observatorio del Teide (Tenerife). The camera will employ a 256 X 256 InSb focal plane array, and will be used in the 1 - 5 micron atmospheric windows. The

The relations between the angular momentum (J) and the mass (M) for a sample of spiral galaxies are discussed for galaxies distributed in the rotational velocity (V) - size (R) plane. It is found that, for a given mass, Sc galaxies have larger angular momentum (~20%) than Sa. The absence of segregation in the angular momentum (J) - mass (M) plane

We apply the spherical infall model to compare the observed distribution of radial velocities of galaxies around Coma with predictions that are based on optical and X-ray overdensity profiles. Two optically selected galaxy catalogues, the CfA redshift survey and a UKST plate scanned with the APM, are used to determine the overdensity profile of the

EL OBJETIVO DE ESTA TESIS HA SIDO EL ESTUDIO DE REGIONES EXTENSAS DE LINEAS DE EMISION ESTRECHAS (RELE) ASOCIADAS A GALAXIAS ACTIVAS, CON EL FIN DE DETERMINAR EL DIAGRAMA POLAR DEL CONTINUO IONIZANTE NUCLEAR Y CON ELLO RESTRINGIR LOS PARAMETROS DE LOS MODELOS DE LA FUENTE DE DICHO CONTINUO. PARA ELLO SE HAN COMBINADO OBSERVACIONES CON
