En esta tesis se presentan los resultados de la fotometría B, V, I y Halfa de una muestra de once pares de galaxias en fusión menor. Se determinaron la magnitud total y los colores integrados para cada galaxia. Se construyeron ...

La galaxia espiral M83, una SBb a tan sólo 4,5 Mpc, posee el núcleo starburst más cercano. En esta tesis se presenta un estudio multibanda, utilizando diversas técnicas de espectroscopía 2D-3D.

Collimated outflows (jets) appear to be a ubiquitous phenomenon associated with the accretion of material onto a compact object. Despite this ubiquity, many fundamental physics aspects of jets are still poorly understood ...

The Ca II triplet (CaT) feature in the near-infrared has been employed as a metallicity indicator for individual stars as well as integrated light of Galactic globular clusters (GCs) and galaxies with varying degrees of ...

In the present PhD thesis will be fully addressed the analysis of the ultra-energetic events detected by the Pierre Auger Observatory. He will extend the correlation analysis of what was done previously in the Pierre Auger ...

Context. The detection of magnetic chemically peculiar (CP2) stars in open clusters of extragalactic systems can give observational answers to many unsolved questions. For example, one can study the influence of different ...

Context. Spectroscopic investigations of galactic open clusters are scarce and limited to a reduced sample of cluster members. Aims. We intend to perform a complete study of the physical parameters of two galactic clusters ...
