Abstract: In this talk, we introduce the field of General Relativistic Magnetohydrodynamics (GRMHD) and give an overview on recent effort toward simulating and visualizing astrophysically realistic gas dynamics around compact binaries. In particular we motivate our group's approach, where a post-Newtonian expansion is used to construct an analytic spacetime, and we show preliminary results of circumbinary disks surrounding an equal-mass non-spinning black hole binary.

Abstract: (2+1)-dimensional gravity allows us to study aspects of classical and quantum gravity in a simpler technical setting which retains much of the conceptual complexity of the standard (3+1)-dimensional gravity. However, pure Einstein gravity lacks propagating degrees of freedom in 2+1 dimensions.

Abstract: Teleparallel gravity is an alternative theory of gravitation. It is entirely equivalent to General Relativity in what concerns dynamical evolution. The main advantage of such a theory is that in its realm it is possible to define an expression for the gravitational energy.
