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.
Zeus Sales Moreira successfully defended his Ph.D. thesis on March 31st 2025, which was advised by C. Herdeiro. The committee was composed by Profs. Darío Nunez, Eugen Radu, Alberto Saa and Gonzalmo Olmo and unanimously praised the excellent work of the candidate. Congratulations Zeus and all the best for the future!
Relativistic hydrodynamics has undergone major development over the past three decades, notably through high-resolution shock-capturing schemes enabled by conservative formulations of the relativistic fluid equations.
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.
One of the most efficient energy sources in the universe is the matter accretion onto compact objects, such as black holes (BHs) and neutron stars (NSs). Since magnetic fields are ubiquitous everywhere, the accretion flow is expected to be magnetized in nature, where the large-scale magnetic fields inside the disks are commonly rooted either from the companion star or the interstellar medium.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
