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.
Hairy black holes can form dynamically
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.
Data for Kerr black holes with Proca hair
Here, the numerical data described in the paper "Kerr black holes with Proca hair", arXiv:1603.02687 [gr-qc] [1], is made available for public use.
Mengjie Wang's PhD exam
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!
