Description
Dark matter constitutes the majority of the matter content of the Universe, yet its fundamental properties remain unknown. Its presence is inferred through its gravitational effects on cosmic structures across all scales. Galaxy clusters, which are the most massive gravitationally bound systems in the Universe, are particularly powerful environments for probing the nature of dark matter due to their high dark matter densities.
Self-interacting dark matter (SIDM) has been proposed as a potential solution to tensions between observations and dark matter-only simulations. Particle self-interactions can produce observable signatures, including (but not limited to) altered halo shapes and density profiles, and changes in gravitational lensing signals.
The Three Hundred Project is a large suite of simulated galaxy clusters, modelled using full-physics hydrodynamical re-simulations and semi-analytical techniques. In this talk, I will introduce a new suite of zoom-in simulations of galaxy clusters within this framework that incorporate SIDM. These simulations offer a detailed view of SIDM effects in realistic, high-mass cluster environments, and will enable us to provide new constraints on the SIDM cross-section.
