The exponential growth of the exoplanet detection frequency in the past years has led to a great improvement in our understanding of the population of planets in the galaxy; of which the Earth is one, yet we are still very much at the beginning of a long road ahead. The aim of this thesis work is...

El crecimiento exponencial del número de exoplanetas descubiertos en los últimos años ha derivado en un mayor entendimiento de los planetas en la galaxia, de los cuales la Tierra es miembro; pero aún nos queda un gran camino por delante. El propósito de esta tesis es descubrir y confirmar nuevos ...

Para trazar flujos entrantes y salientes en núcleos de galaxias activas (AGNs), determinar la masa de gas involucrada y su impacto en la galaxia hu ́esped y en el agujero negro central, se requieren estudios en imágenes 3-D de tanto gas ionizado como molecular. Estudios previos de imagen han rev...

Tracing nuclear inflows and outflows in active galactic nuclei (AGNs), determining the mass of gas involved in these, and their impact on the host galaxy and nuclear black hole, requires 3-D imaging studies of both the ionized and molecular gas. Previous imaging studies have revealed a correla...

In the last few years evidence has been growing that the structure of the Galactic Bulge is very complex. Several independent studies suggest the presence of more than one stellar populations in the bulge, with different origins and a relative fraction changing across the bulge area. To character...

In spite of the efforts focused on understanding the formation of high mass stars, we do not have a clear understanding of which are the processes involved. To understand it, we need to characterize objects in very early stages of evolution and therefore infer the initial conditions of these proc...
