Advances in computer power and in simulation algorithms have made it possible to carry out simulations of the formation and evolution of galaxies throughout regions as large as those mapped by recent surveys of the local Universe.

Radio-loud AGNs can inhabit regions with a very rich ISM. The presence of this rich medium is likely related to the origin and evolution of the host galaxy and of the active nucleus. Recent observations show that a large fraction of radio galaxies contains a significant young stellar population.

La interacción de la luz solar con el grano cometario (cola de polvo) da lugar al fenómeno de la extinción. Una parte de la radiación solar incidente es absorbida por el grano y reemitida en el infrarrojo.

An analytical and numerical study of the sensitivity of weak solar photospheric lines to temperatures, velocities, and magnetic fields has been developed. Our investigation is based on the concept of response functions (Ruiz Cobo & del Toro Iniesta 1994).

According to the hierarchical scenario, galaxies form in dark matter halos which grow via merging and accretion of small objects.
The CRISTA experiment (CRyogenic Infrared Spectrometers and Telescopes for the Atmosphere) measured the global distribution of infrared limb emission spectra in the Earth atmosphere during 2 Space Shuttle missions in November 1994 and August 1997.
