Black holes are the most massive objects in the Universe and provide an ideal testing ground for gravity in the strong field regime.
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.

Two positions for a Researcher (with Ph.D.) are open within the project Towards Precision Tests of Ultralight Dark Matter with Gravitational Imaging Waves. Application deadline: March 13, 2025. More info in Euraxess.
Next generation of gravitational wave detectors will have the sensibility to detect potential deviations in gravitational waveforms with respect to general relativity. However, current agnostic tests are plagued by a lack of realistic deviations, making it difficult to interpret such detections with respect to specific theories.

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.
