  • Gabbanelli, Luciano (Date of defense: 04-11-2019)
    For ninety years we have known that our universe is in expansion. Cosmological data favor an unknown form of intrinsic and fundamental uniform energy contributing approximately 68% of the total energy budget in the current ...
  • Casamiquela Floriach, Laia (Date of defense: 23-06-2017)
    This thesis has as a main purpose the determination of the chemical composition of Open Clusters for the study of the chemical gradients in the Galactic disc with: Galactocentric radius, position above the plane, and ...
  • Juárez Rodríguez, Carmen (Date of defense: 26-06-2017)
    Turbulence, magnetic fields and gravity driven flows are important for the formation of new stars. Although magnetic fields have been proven to be important in the formation of stars, only a few works have been done ...
  • Moreno de la Cita, Víctor (Date of defense: 28-04-2017)
    In this thesis we have developed a tool for the computation of non-thermal emission in astrophysical sources. The code reads the hydrodynamic data coming from relativistic hydrodynamic simulations and compute the injection, ...
  • Pérez Ràfols, Ignasi (Date of defense: 03-10-2016)
    The work presented in this Ph.D. thesis is mostly related to the measurement and interpretation of the cross-correlation of different species. This is achieved using spectroscopic data from the BOSS survey of which I am a ...
  • Maneu Victoria, Jordi (Date of defense: 20-12-2019)
    Double § hypernuclei are bound systems of several nucleons and two § hyperons. These systems are unstable with respect to the weak interaction and chiefly decay through two-body processes that conserve neither parity, ...
  • Bellomo, Nicola (Date of defense: 24-01-2020)
    Cosmology is the study of the origin and evolution of our Universe as a whole. Even if the theoretical framework of Cosmology was developed a century ago, with the formulation of General Relativity by Albert Einstein, it ...
  • Gontcho, Satya Gontcho A (Date of defense: 22-09-2017)
    The work we present in this manuscript revolves around the use of quasar spectra to probe the Universe. Absorption features in the electromagnetic spectrum of bright distant quasars by ionized hydrogen give us access to ...
  • Torres i Albà, Núria (Date of defense: 14-10-2019)
    This thesis has as an objective the study of very energetic phenomena in the central regions of active galaxies. Intense star formation is triggered by mergers of galaxies, and the funneling of large quantities of gas ...
  • Triana Iglesias, Miquel (Date of defense: 21-09-2017)
    The gauge/gravity duality has proven to be a very useful tool in the understanding of quantum field theories outside the perturbative regime. In particular, holography has been able to shed light not only on generic ...
  • Mujal Torreblanca, Pere (Date of defense: 22-11-2019)
    In this thesis, we study the physical properties of several ultracold few-boson systems depending on the interactions between their constituents. Nowadays, experimentally, it is possible to have great control with high ...
  • Feijoo Aliau, Albert (Date of defense: 21-09-2017)
    The purpose of this thesis has been to study the S=-1 meson-baryon interaction in S-wave employing an effective chiral SU(3) lagrangian up to NLO and implementing unitarization in coupled channels. Such a study requires ...
  • Alsina Leal, Daniel (Date of defense: 18-09-2017)
    Quantum information science has grown from being a very small subfield in the 70s until being one of the most dynamic fields in physics, both in fundamentals and applications. In the theoretical section, perhaps the feature ...
  • González Boquera, Claudia (Date of defense: 13-01-2020)
    The proper understanding of the equation of state (EoS) of highly asymmetric nuclear matter is essential when studying systems such as neutron stars (NSs). Using zero-range Skyrme interactions and finite-range interactions ...
  • Torrents Verdaguer, Genís (Date of defense: 27-06-2016)
    Maldacena's conjecture, often known as the holographic duality or the AdS/CFT correspondence, proposes an equivalence between gravitational theories in a hyperbolic space of a certain dimensionality and gauge theories ...
  • Santos-Oliván, Daniel (Date of defense: 12-07-2017)
    In this thesis we study several open problems using Numerical Relativity on asymptotically Anti-de Sitter (AdS) spacetimes. The understanding of the dynamics of AdS is interesting not only because of pure theoretical reasons ...
  • Martínez Montero, Marina (Date of defense: 14-10-2016)
    This thesis has focused entirely on classical and thermodynamical aspects of black hole physics. We have developed four different projects involving different kinds of black holes. 1 BLACK BRANES IN A BOX Neutral black ...
  • Rives Molina, Vicente José (Date of defense: 17-11-2016)
    This thesis is divided in different sections. After a short introduction about the thesis contents, the theory chapter presents the Standard Model of Particle Physics (SM), with an emphasis on those properties of flavour ...
  • Galindo Fernández, Daniel (Date of defense: 27-07-2018)
    In our Galaxy, supernova remnants and pulsars are the two most numerous populations of non-thermal objects. The goal of this thesis is to study the extreme gamma-ray emission from these two astrophysical objects with Fermi ...
  • Gómez Valent, Adrià (Date of defense: 12-09-2017)
    The cosmological constant appearing in Einstein’s equations is a key element of the ΛCDM standard cosmological model. This term performs, effectively, as pure vacuum energy, and is considered the easiest explanation of the ...
