This event is meant to study the connections between quantum fields in curved spacetimes with horizons and the effective field theory methods as applied to open systems (Open EFTs). In particular the hope is to exploit the existence of tools (from areas like optics) for dealing with hierarchies of scale in open systems and adapt the to see if they can inform our understanding of controlling late-time predictions in gravitational environments. Please note that this meeting is by invitation only.
Computational Methods for General Relativistic Magnetohydrodynamics are important means of studying compact astrophysical objects such as neutron stars and core-collapse supernovae relevant e.g. to understand sources of gravitational radiation.Particular crucial elements of such methods including solving non-linear equations to extract the microphysical state from the conserved fluxes (endearingly called con2prim) or handling realistic equations of state (EOS) that are only given approximately in a tabulated manner. The state of the art for algorithms addressing these issue leaves to be desired and significantly limits stabilityaccuracy and performance of todays calculations.This workshop aims to review the known algorithmic and computational shortcomings list requirements that an ideal solution should haveand discuss potential practical solutions.
With the advent of black hole imaging, we are now moving forward to black hole cinema. This workshop aims to collect the expertise across the Event Horizon Telescope Collaboration to develop, implement and apply methods to access and interpret variability in M87 and Sgr A*. The goal is to lay the foundation for the first publications based on black hole movies.
