Dynamics and secular evolution processes in galaxies – Matías Blaña

In this talk I invite you to hear an overview of projects that explore dynamical processes that drive secular evolution processes in galaxies. In the first part we will see the main properties of barred galaxies and how these substructures can drive internal processes in disk galaxies and co-exist and transform other substructures such as classical bulges. We will explore the results of modelling the observations of our beautiful neighbour the barred Andromeda (M31) galaxy, which will help us in modelling the Great Barred Galaxy NGC1365 in the Fornax galaxy cluster. In the second part we will explore how satellite galaxies can evolve as they are accreted into their host systems. We will first focus on the entry of pristine and backsplash satellites in the Milky Way, where I model their galactic orbits and hydro-dynamical interaction with the Galactic circumgalactic medium. To conclude I will present our latest results analyzing the properties of the satellite galaxies in the Fornax galaxy cluster, finding a transition radius that reveals regions of satellites with different properties, a substructure that we also find in different environments like the Virgo galaxy cluster, the Milky Way and the Andromeda galaxies, as well as in cosmological galaxy simulations.
