[eng] In this thesis we have presented a new method to search for tidal streams generated by globular clusters in the Gaia catalogue. This statistical method is based on the maximum likelihood technique to distinguish stream stars from foreground fie

El Medi Intergalàctic permet una caracterització de propietats bàsiques de l'univers tals com paràmetres fonamentals del model cosmològic, el creixement de pertorbacions primordials de densitat i formació de galàxies. Aquesta caracterització

Simulations have shown to be one of the best tools to study properties of galactic large scale structures and their effects on to the local kinematics of stars. The aims of this thesis are: i) To obtain realistic N-body models that allow us to analys

The understanding of the origin and evolution of the Milky Way is one of the primary goals of the Gaia mission (ESA, launch autumn 2013). In order to study and analyse fully the Gaia data it will be useful to have a Galaxy model able to test various
