Located at about 8 kpc from the Sun, the centre of our Galaxy is an excellent laboratory to study the complex processes occurring at the heart of galaxies with unequalled spatial resolution. It is a unique object of study, which concentrates a large number of interdependent research subjects. The Galactic Centre is in fact a very rich region where the supermassive black hole Sagittarius A*, numerous compact objects, stellar populations including several star clusters, molecular clouds and ionised gas, possibly intense magnetic fields, as well as extreme phenomena and, perhaps, dark matter, all come together. Numerous results on the Galactic centre have been published in recent years, shedding new light on the energetic events taking place at the Galactic centre. Nevertheless, the 3D structure, dynamics and interactions between these different components, which are essential for interpreting the observations, are still poorly understood.
The aim of this workshop is therefore to bring together the community interested in this region or in processes taking place in it, in order to discuss the latest advances, possible links between their work and to encourage new collaborations. The proposed themes therefore include all scales, all wavelengths and all methods of analysis, whether observations, theoretical modelling or numerical simulations, and aim to cover all the objects and structures present in the Galactic centre or emanating from this region.
Topics:
- Sagittarius A*
- Interstellar medium
- Magnetic field
- Stellar formation and populations
- Dynamical modelling
- High-energy processes
- Plasma physics
- General relativity
- Dark matter
- Feedback and large-scale interactions
- Activity cycles in relation to other galactic nuclei
This workshop covers themes that are present in various Actions Thématiques (AT-PEM, CG, PCMI, PS). It will provide an opportunity for these communities to meet and discuss their observations, results and methods of analysis. The proposed workshop will also provide a comprehensive overview of our current knowledge of the Galactic centre for those who are not already familiar with this complex region.
