Gravitational Lensing Signatures for Fuzzy Dark Matter

The leading candidate for dark matter has been Weakly Interacting Massive Particles (WIMPs), but they have not yet been detected directly or indirectly. Additionally, observations of dwarf galaxies challenge the viability of WIMPs as dark matter candidates. Alternative models, such as Fuzzy Dark Matter (FDM), which consists of much lighter particles, have gained increasing interest. Different types of dark matter would influence galaxy formation differently, resulting in distinct mass distributions; for example, FDM galaxies would feature unique flat inner regions. We use advanced simulations of galaxies formed from WIMPs and FDM to model their behavior as strong gravitational lenses. We present preliminary results from our study on the strong lensing properties, such as critical curves and caustics, of Fuzzy Dark Matter galaxies derived from simulations, and compare them with those of their WIMP counterparts.
