El objetivo fundamental de esta tesis es el estudio de la estructura de las regiones centrales de galaxias con disco, con particular atención al estudio de los bulbos y de las barras, y a los procesos de formación y evolución de estas componentes. Con esta finalidad, han sido analizadas las propiedades estructurales y fotométricas de los bulbos y

A Deformable Mirror Controller (DMC) has been devised to overcome the open-loop nature of Multi Object Adaptive Optics (MOAO), in particular for AO systems with update rates of 1 ms or less. The system is based on a figure sensor, which uses a monochromatic illumination source and a Shack-Hartmann (SH) wavefront sensor (WFS) to obtain a fine

The correction of the wavefront in optical systems implies the use of wavefront sensors, software, and auxiliary optical systems. We propose evaluated the wavefront using the fact that the wavefront and its intensity are related in the mathematical expression the irradiance transport equation (ITE)

We report a new observation of Nova Vul 2007 (S. Nakano, IAUC 8861) obtained by the Swift X-ray Telescope (XRT) on 2008 June 18. The nova was detected at count rate of 0.023 count/s, representing a decline by a factor of 3 compared with Swift XRT observations obtained during 2007 November- December, and by about 50% compared with the previous
