Abstract: The ESO/GRAVITY is an adaptive optics and fringe tracker assisted K-band interferometric spectrograph. The instrument development started in the last decade and reached first fringes with the auxiliary telescopes in December 2015.
Abstract: We discuss how space-time singularities inside black holes can be resolved using the Palatini approach for modified gravity. In this approach metric and affine connection are taken as independent variables.
In 2014, it was found that black hole (BH) solutions in General Relativity exist in stationary equilibrium with (good) matter: hairy BHs. An investigation published in Physical Review Letters shows, in a toy model, that analogous hairy BHs can form dynamically.
Gr@v's Ph.D. student Mengjie Wang successfully defended his doctoral thesis with title "Quantum and classical aspects of scalar and vector fields around black holes", on February 29th 2016. Mengjie integrated the MAP-Fis Ph.D. programme and was supported by a grant from the IDPASC doctoral programme. Congratulations Mengjie!
Abstract: We investigate the thermodynamics of spherically symmetric black hole solutions in a four-dimensional Einstein--Yang-Mills-SU(2) theory with a negative cosmological constant. Special attention is paid to configurations with a unit magnetic charge.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
