The old dream of integrating into one the study of micro and macrocosmos is now a reality. Cosmology, astrophysics and particle physics converge within a scenario (but still not a theory) of cosmic structure formation and evolution called Λ Cold Dark Matter (ΛCDM). This scenario emerged mainly to explain the origin of galaxies. In these lecture notes, I first present a review of the main galaxy properties, highlighting the questions that any theory of galaxy formation should explain. Then, the… 

Study of new dark matter production mechanisms and their possible signatures

This thesis is devoted to the study of the nature of Dark Matter (DM). To this end we investigate both its generation mechanisms and detection possibilities. We mainly focus on interesting simple

DETECTING TRIAXIALITY IN THE GALACTIC DARK MATTER HALO THROUGH STELLAR KINEMATICS. II. DEPENDENCE ON NATURE DARK MATTER AND GRAVITY

Recent studies have presented evidence that the Milky Way global potential may be non-spherical. In this case, the assembling process of the Galaxy may have left long-lasting stellar halo kinematic

Low-mass Galaxy Formation in Cosmological Adaptive Mesh Refinement Simulations: The Effects of Varying the Sub-grid Physics Parameters

We present numerical simulations aimed at exploring the effects of varying the sub-grid physics parameters on the evolution and the properties of the galaxy formed in a low-mass dark matter halo (∼7

Galaxies and Cladistics

TLDR
Interpreting formation and evolution of galaxies as a 'transmission with modification' process, it is shown that the concepts and tools of phylogenetic systematics can be heuristically transposed to the case of galaxies.

ON THE BARYONIC, STELLAR, AND LUMINOUS SCALING RELATIONS OF DISK GALAXIES

We explore how the slopes and scatters of the scaling relations of disk galaxies (Vm–L[–M], R–L[–M], and Vm–R) change when moving from B- to K-bands and to stellar and baryonic quantities. For our

Cosmological Density Perturbations Degree Project of 15 ECTS credits Physics Programme

This thesis presents a brief review of gravitation and cosmology, and then gives an overview of the theory of cosmological perturbations; subsequently some applications are discussed, such as

Galaxy colour, morphology and environment in the Sloan Digital Sky Survey

We use the Fourth Data Release of the Sloan Digital Sky Survey to investigate the relation between galaxy rest-frame u-r colour, morphology, as described by the concentration and Sersic indices, and

The Universal Rotation Curve of Spiral Galaxies: I. the Dark Matter Connection

We use a homogeneous sample of about 1100 optical and radio rotation curves (RCs) and relative surface photometry to investigate the main mass structure properties of spirals, over a range of 6

Galaxy morphology in rich clusters: Implications for the formation and evolution of galaxies

A study of the galaxy populations in 55 rich clusters is presented together with a discussion of the implications for the formation and/or evolution of different morphological types. A well-defined

The formation and evolution of galaxies within merging dark matter haloes

We construct semi-analytic models for galaxy formation within the framework of a hierarchical clustering scenario for structure formation in the Universe. We use the algorithm of Kauffmann & White to

Rotation curves from baryonic infall : dependence on disk-to-halo ratio, initial angular momentum, and core radius, and comparison with data

Using a simple analytic model of the response of dark matter halos to the dissipative infall of the luminous material to form an exponential disk, we explore the dependence of the final rotation

DECLINING ROTATION CURVES - THE END OF A CONSPIRACY

New observations of H I rotation curves at the Very Large Array have uncovered two galaxies with rotation curves declining between 1 and 3 optical radii. The velocity decrease is large, more than 50

On the fragmentation of cosmic gas clouds. I. The formation of galaxies and the first generation of stars.

The formation of galaxies is studied in the context of the fragmentation of massive diffuse ionized gas clouds. A semiquantitative discussion of the role of cooling indicates that there is a
