Abstract

Bars are ubiquitous in galaxies, including in early-type systems where about 50% of them showing signs of present or past bar tumbling systems. As numerical simulations progress in terms of mass and spatial resolution, physics of the ISM and star formation, turbulence, we can start to address important questions such as the role of bars on the triggered star formation in galaxies, the advent of double bars (embedded structured) observed in nearby objects, and the fueling of central black holes. A PhD candidate would lead efforts associated with state-of-the-art numerical (hydrodynamical) simulations (mostly, but not only, with the Adaptive Mesh Refinment code RAMSES) of bars to understand their role in the secular evolution of galaxies. The output of these simulations should be analysed together with a unique set of photometric and spectroscopic data, partly coming from the Atlas3D project, and also from other observational programmes (e.g., NGVS). The PhD project will therefore combine the set up, running and analysis of simulations and the analysis of existing (and potential request for new) observations. This PhD will be conducted in close contact with an international team of theorists and observers from various countries (France, UK, Canada, US, Chile, etc), and can lead to further theoretical developments or e.g., participation to observing runs at various facilities (VLT, WHT, etc) depending on the interests of the PhD student.
