In nature there are groups and clusters of galaxies that present a large difference in luminosity between their two brightest members. These galaxy aggregations are called fossils and they host the most luminous and massive galaxies in the Universe. How did fossil systems form? Which are the mechanisms driving their evolution? Which are the

La Cámara Plenóptica es un concepto que proviene del campo de la fotografía computacional, y que surge como herramienta para capturar una cantidad aprovechable de muestras de la Función Plenóptica, o ¿Light Field¿. Esta función, de cuatro variables espaciales que recorren la apertura y el plano focal de un sistema óptico que genera imagen

``Clusters of galaxies are the largest virialised systems in the Universe'' is one of the most common statements in the framework of galaxy clusters research. This occurs because such gravitationally bound structures become ideal laboratories to directly study their baryon content (intracluster medium and galaxies) and to indirectly measure their

We present in this thesis a study of the kinematics of the ionized gas in 12 interacting galaxies using observations made with a Fabry-Perot interferometer, and a study of the kinematics of the molecular gas in one of the systems of our sample using observations taken with a radiointerferometer. We study the interacting galaxy pair Arp 270 which

El descubrimiento relativamente reciente de los primeros exoplanetas ha transformado nuestra manera de los ver los planetas de nuestro Sistema Solar. Desde esta nueva perspectiva, nuestros vecinos nos proporcionan una valiosa información que puede ser usada como punto de referencia para analizar datos exoplanetarios. Esta tesis se centra en la

Quasars are considered to be the most luminous subclass among Active Galactic Nuclei. Although they appear to be distributed everywhere in the Universe, only a small fraction of them happen to be part of a fortuitous alignment with a galaxy or a galaxy cluster that lies along the line-of-sight, which results in multiple images of the background
