Strong Gravity

The study of regular black holes and black hole mimickers as alternatives to standard black holes has recently gained significant attention, driven both by the need to extend general relativity to describe black hole interiors, and by recent advances in observational technologies.

We examine the images and shadows of thin accretion disks around rotating hairy black holes characterized by two non-trivial, time-periodic scalar fields, whose target space possesses non-flat Gaussian curvature.

The magnetic field configuration in the interior of Neutron Stars is an open problem and may be impacted by the influence of a turbulent cascade within the star. Assessing the impact of turbulent flow with numerical simulations requires incredibly high resolution as well as long lived simulations covering multiple Alfven times.
