Martínez Montero, Marina (Data de defensa: 2016-10-14)
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 ...
Bellomo, Nicola (Data de defensa: 2020-01-24)
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 ...
Triantafyllou, Nikolaos (Data de defensa: 2021-11-12)
The standard cosmological model, ΛCDM, with the addition of an early inflationary phase, provides an accurate description of a nearly flat and homogeneous Universe, at large scales, which expands ...
Oncins Fernández, Marc (Data de defensa: 2022-06-03)
The existence of black holes that go beyond the mass given by their stellar origin has been known for some time. On the lower end, a subset of primordial black holes (PBHs) could form all of the dark ...
Fernández Núñez, Isabel (Data de defensa: 2018-07-19)
In physics, it is common to find different phenomena being described by similar equations. A good analogy can make us look at a problem from a different point of view. In that way, ideas may be transferred ...
Escrivá Mañas, Alberto (Data de defensa: 2021-06-21)
This thesis has been devoted to the study of the gravitational collapse of spherically symmetric perturbations on a Friedman-Robertson-Walker (FRW) universe filled by a perfect fluid. Large cosmological ...
Gabbanelli, Luciano (Data de defensa: 2019-11-04)
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 ...
