A centrally heated dark halo for our Galaxy

Abstract:

We construct a new family of models of our Galaxy in which dark matter and disc stars are both represented by distribution functions that are analytic functions of the action integrals of motion. The potential that is self-consistently generated by the dark matter, stars and gas is determined, and parameters in the distribution functions are adjusted until the model is compatible with observational constraints on the circularspeed curve, the vertical density profile of the stellar disc near t...
