The greatest challenge in black hole astrophysics lies in the attempt to unify Galactic, intermediate and supermassive black holes under the same physical scheme to gain a more profound understanding of different classes of objects. In such grand-unification models, the observed behaviours and manifestations of accreting black holes are driven by only a few fundamental parameters, such as mass, accretion rate and spin. The conference tackles the issues related to accretion physics, production of jets/winds/outflows and their time evolution by putting a particular emphasis on the role of the net accretion rate onto black holes of all sizes. We are going to explore to which extent grand-unification schemes of black hole accretion are possible and also where they possibly fail. Participants are encouraged to present theoretical and/or observational results and prospects, across the entire electromagnetic spectrum, and to discuss them in the light of grand-unification paradigms of black hole accretion.
Topics suggested for the conference :
- Accretion / ejection flows around black holes: theory and observational predictions
- Disks, winds and jets at different accretion rates: observations and phenomenology
- XRBs and AGN grand-unification and scaling relations – what do they mean and where do they fail?
- Ultraluminous X-ray sources and intermediate mass black holes – the missing link?
- Time scales and variability in different accretion states
- Spin evolution and black hole mergers
- Feeding and feedback across the mass scale
