AGN Variability in the era of Big Data

| Sumario: | Active Galactic Nuclei (AGN) are characterized by their time–variable continuum flux in every waveband in which they have been studied. However, we do not completely understand the mechanisms that drive such variations. In particular, we are missing significant details of how AGN variability at different wavelengths is related, and how physical properties of the central engine are related to well defined variability properties of the system. The main goal of this thesis is to better understand the physics behind AGN variability, and to provide a variability–based AGN selection technique, in order to obtain less biased AGN samples, which can allow us to understand in a better way how these objects are formed and how they evolve. |
