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 ...
Munar i Adrover, Pere (Fecha de defensa: 2014-03-28)
The high energy astrophysics, specifically the gamma-ray astrophysics, studies the processes that cannot be caused by hot matter but by other mechanisms colled non thermaland processes, which involve matter with energies ...
Castañeda Pons, Javier Bernardo (Fecha de defensa: 2015-12-15)
Gaia is an extremely ambitious astrometric space mission adopted within the scientific programme of the European Space Agency (ESA) in October 2000. It aims to measure with very high accuracy the positions, motions and ...
Shinde, Mahesh (Fecha de defensa: 2016-02-01)
The investigation of climate variability in different timescales such as daily, monthly, seasonal and inter-annual has utmost importance for managing the socio-economic processes on regional to global scale. Indeed, the ...
O'Mullane, William (Fecha de defensa: 2012-03-23)
As is the way with books in general this document is presented in the form of chapters (seven in number) devoted to individual topics relating to the overall topic of Gaia astrometric data processing. We progress logically ...
Marcos Matamoros, Raül (Fecha de defensa: 2016-02-09)
This thesis studies the benefits of different calibration approaches on seasonal forecasting and the improvement of seasonal prognosis of water resources and forest fires. Droughts and wildfires are an inherent problem to ...
Caballero García, María Dolores (Fecha de defensa: 2008-06-27)
En esta tesis utilizamos los instrumentos de altas energías del satélite INTEGRAL para hacer espectroscopía y la cámara OMC para hacer fotometría de dos tipos diferentes de objetos celestes emisores ...

The cosmic expansion history tests the dynamics of the global evolution of the universe<br/>and its energy density contents, while the cosmic growth history tests the evolution of the<br/>inhomogeneous part of the energy ...
Font Ribera, Andreu (Fecha de defensa: 2011-09-30)
[cat] Gran part dels estudis presentats en aquesta tesi doctoral estan vinculats als esforços per detectar les oscil·lacions acústiques dels barions (BAO, de l’anglès Baryon Acoustic Oscillations) en la funció de correlació ...
Frau Méndez, Pau (Fecha de defensa: 2012-06-12)
It is some observational evidence that dense cores are the birthplace of low-mass stars. These regions, apparently quiescent, are capable of surviving several free-fall times and, potentially, collapse and form stars. ...
Bordas Coma, Pol (Fecha de defensa: 2009-10-14)
[eng] The present thesis focuses on the investigation of some of the high energy processes ocurring in microquasars. The matter content and the power transported in the jets of microquasars are studied, the effects that ...
Roca Fàbrega, Santi (Fecha de defensa: 2014-11-26)
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 ...
Udina Sistach, Mireia (Fecha de defensa: 2015-12-10)
The atmospheric boundary layer in stably-stratified conditions and over non-homogeneous terrain becomes a complex system with many interactions of physical processes occurring in a wide range of different spatial and ...
Manrique Oliva, Alberto (Fecha de defensa: 1995-09-26)
En la tesis se presenta un método semianalítico para describir el crecimiento de objetos virializados en el escenario de inestabilidad gravitatoria. Se ha desarrollado el formalismo del sistema confluente de trayectorias, ...
Trapero i Bagué, Laura (Fecha de defensa: 2014-12-03)
Els episodis de precipitació intensa en zones de muntanya sovint es veuen afavorits pels efectes orogràfics que actuen com a mecanismes que modifiquen la precipitació. Aquest treball vol contribuir a millorar el coneixement ...
Arasa Agudo, Raúl (Fecha de defensa: 2011-07-20)
Durant les últimes dècades la quantitat de gasos i partícules contaminants que s’han injectat a l’atmosfera ha augmentat considerablement. Evidència d’aquesta informació són les elevades concentracions de diòxid de nitrogen ...
Rodríguez Gasén, Rosa (Fecha de defensa: 2011-05-06)
Gradual SEP events is one of the greatest hazards in space environment, particularly for the launch and operation of spacecraft and for manned exploration. Predictions of their occurrence and intensity are essential to ...
Solanes Majúa, Josep Maria (Fecha de defensa: 1990-09-28)
El desarrollo de un modelo politrópico y autoconsistente de cúmulo rico de galaxias ha permitido caracterizar las propiedades estructurales y cinemáticas típicas de estos sistemas, así como estudiar detalladamente los ...
