Abstract

We study the systematic problems in determining the local dark matter density $\rho_{dm}(R_\odot)$ from kinematics of stars in the Solar Neighbourhood, using a simulated Milky Way-like galaxy. We introduce a new unbiased method for recovering $\rho_{dm}(R_\odot)$ based on the moments of the Jeans equations, combined with a Monte Carlo Markov Chain technique and apply it to real data. ov
