Description
We present a dynamically self-consistent model of the Milky Way constrained by Gaia observations, which includes a radially anisotropic dark matter (DM) halo component. The component is the result of a galaxy merger and affects the DM velocity distribution functions, which in turn affects the measured DM flux in both heliocentric and geocentric reference frames. Comparing our model with previous ones, we observe a modest but significant effect on the derived DM detection rates. In particular, direction-sensitive detectors would observe a unique kinematic signature caused by the non-Gaussian component.
Our results underline the importance of taking into account the dynamics of our galaxy in the construction of the dark matter model and its effect on potential detections in the future.
