Talks at the DAA. Talk by Luís Arturo Ureña López, from the Grupo de Gravitación y Física Matemática, Universidad de Guanajuato (Mexico). Place: Seminar of the Departament of Astronomy and Astrophysics, 4th floor of the Research Building, at Burjassot. Date: Friday, 23rd of July 2019. Time: 12:00.
ABSTRACT:
The model of ultra-light bosons to conform the dark matter of the Universe has been under strong scrutiny in the last, it has become an alternative reference model to the dark matter of the standard cosmological model. In this publication we present the general results of the model and the observations. For this, we will also explore the types of scalar potentials: the quadratic, the trigonometric and the hyperbolic. For these last two articles, in addition to the boson mass, a role of self-interaction is also considered, which in turn influences the cosmological observables. The results are explained based on a mathematical formalism that allows us to analyze the cases in a unified way.
