  • 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 ...
  • Illa Subiña, Marc (Date of defense: 09-09-2021)
    Nuclei make up the majority of the visible matter in the Universe; obtaining a first principles description of the nuclear properties and interactions between nuclei directly from the underlying theory of the strong ...
  • 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, ...
  • Castro Ginard, Alfred (Date of defense: 30-04-2021)
    Open clusters are groups of stars, gravitationally bound together, that were born from the same molecular cloud and, thus, share similar positions, kinematics, ages and metallicities. Traditional methods to detect open ...
  • Lu, Zujia (Date of defense: 26-04-2022)
    Star formation is a fundamental and still largely unsolved problem of astrophysics and cosmology. Its complexity stems from the complex interaction of turbulence, magnetic fields and gravity, and from the onset of different ...
  • 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 ...
  • Katanaeva, Alisa (Date of defense: 10-02-2021)
    AdS/CFT correspondence combines ideas of holography and duality in a way that allows one to make calculations in the otherwise hardly accessible (strongly coupled) regime of the target theory. In this thesis we are interested ...
  • de Cruz Pérez, Javier (Date of defense: 16-04-2021)
    En aquesta tesi s’estudien diferents models cosmològics, tots ells caracteritzats per considerar, de manera efectiva, una lleu evolució temporal de l’Energia Fosca, en contrast amb l’actual model estàndard de la cosmologia. ...
  • 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 ...
  • Esteban Muñoz, Iván (Date of defense: 10-09-2020)
    At the end of the 20th century, experiments studying neutrinos coming from the Sun and cosmic rays hitting the atmosphere revealed that these particles can change their flavour, behaving in a way that the Standard Model ...
  • 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 ...
  • Molina Lumbreras, Edgar (Date of defense: 29-09-2021)
    Some binary systems consisting of a compact object, which can be either a neutron star or a black hole, and typically a non-degenerate companion star, have been shown to emit broadband radiation from radio up to gamma-ray ...
  • 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 ...
