Galindo Fernández, Daniel (Data de defensa: 2018-07-27)
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 ...
Lu, Zujia (Data de defensa: 2022-04-26)
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 ...
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 ...
Juárez Rodríguez, Carmen (Data de defensa: 2017-06-26)
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 ...
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 ...
Tous Mayol, José Luis (Data de defensa: 2024-04-12)
[eng] Astronomers have known of the existence of lenticular galaxies (S0) almost as long as they have known that there are other galaxies besides the Milky Way. While it is accepted that spiral galaxies ...
Cruces Mateo, Diego (Data de defensa: 2023-12-13)
[eng] From the observation of the cosmic microwave background radiation (CMBR) we know that the universe is isotropic on scales larger than ∼ 75 Megaparsec to at least one part in 100000. The leading ...
Jiménez Arranz, Óscar (Data de defensa: 2024-04-08)
[eng] The more clearly visible galaxies to the naked eye in the night sky are the Magellanic Clouds (MC), the biggest galaxies in the Milky Way (MW) neighbourhood. Because they are so close, the Large ...
Barneo González, Pablo José (Data de defensa: 2024-01-19)
[eng] Since the first experimental evidence for the existence of gravitational waves in 2015, the amount of data in this scientific area has increased enormously. There has also been a great deal of ...
