Dark Matter Superfluidity and Galactic Dynamics

Understand

We propose a unified framework that reconciles the stunning success of MOND on galactic scales with the triumph of the LambdaCDM model on cosmological scales.

• This is achieved through the physics of superfluidity.
• Dark matter consists of self-interacting axion-like particles that thermalize and condense to form a superfluid in galaxies, with ~mK critical temperature.
• The superfluid phonons mediate a MOND acceleration on baryonic matter.
