Abstract: With the numerous pieces of evidence for the close evolution of super-massive black holes (SMBHs) and their host galaxies throughout the cosmic history, there has been a great effort to understand what drives such fact. One key point which could help achieve that goal is to observe the very first SMBHs in the early Universe and explore the initial conditions and what sets such co-evolution. This talk will guide you through the observational perspectives of this cosmic dance between SMBHs and their hosts, and the some alternative strategies to study them.
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.
Juan Carlos Degollado Daza, who has been a post-doctoral research at Gr@v since 2012, working on numerical relativity, has accepted a permanent professor position at the University of Guadalajara, Mexico. Congratulations Juan Carlos, well done!
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.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
