Short, Kathleen (Data de defensa: 2022-12-12)
[eng] The overwhelming evidence for the existence of dark matter in the Universe, and the discovery of the neutrino masses, are striking indicators of the need for new physics beyond the ΛCDM and Standard ...
Luna, Raimon (Data de defensa: 2020-06-22)
In this thesis we apply new approaches and develop new techniques to address various issues related to fundamental aspects of modern gravitational theory and black holes. We study the behavior of ...
Licht, David (Data de defensa: 2021-04-14)
In this thesis we present a new aspect pertaining to the effective field theory of general relativity in the limit of a large number D of dimensions. We demonstrate that the theory initially developed ...
Pacheco Mateo, Daniel (Data de defensa: 2019-04-30)
The Sun is the main source of all kind of solar energetic particles in the Solar System, electrons, protons and ions with energies from few keV to several GeV. These particles are released from the solar ...
Ser Badia, Daniel del (Data de defensa: 2018-12-21)
The first confirmed detection of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found by radial velocity measurements in a four-day orbit around the nearby star 51 ...
Wijsen, Nicolas (Data de defensa: 2020-04-30)
Our modern society is becoming increasingly dependent on the constant stream of information sent out by satellites orbiting Earth. However, highly energetic rays traversing the near-Earth space environment ...
Tomasevic, Marija (Data de defensa: 2021-09-09)
In this thesis, we explore different ways in which spacetime exhibits peculiar properties when subjected to the rules of quantum mechanics. These rules are naturally implemented at the level of semiclassical ...
Bernal Mera, José Luis (Data de defensa: 2019-09-13)
Cosmology is the science that studies the Universe as whole, aiming to understand its origin, composition and evolution. During the last decades, cosmology has transitioned from a “data staved” to a ...
Gómez Subils, Javier (Data de defensa: 2021-06-22)
In this thesis we have employed the holographic duality to study the non-perturbative regime of a one-parameter family of theories with multi-scale dynamics. Normally, this (super)string theory motivated ...
Linares Arroyo, Hector (Data de defensa: 2021-07-27)
The term light pollution refers to different harmful effects produced by artificial light sources. This phenomena affects observational astronomy, the flora and fauna of the species adapted to the natural ...
