Fuzzy Aquarius: evolution of a Milky-way like system in the Fuzzy Dark Matter scenario

Understand

We present the first high-resolution zoom-in simulation of a Milky-way-like halo extracted from the Aquarius Project in the Fuzzy Dark Matter (FDM) framework.

• We use the N-body code AX-GADGET, based on a particle oriented solution of the Schr\"{o}dinger-Poisson equations, able to detail the complexity of structure formation while keeping track of the quantum effects in FDM.
• The halo shows a cored density profile, with a core size of several kpc for a FDM mass of $m_{\chi}=2.5h \times 10^{-22}\ {\rm eV}/c^2$.
• A flattening is observed also in the velocity profile, representing a distinct feature of FDM dynamics.
