Limits on the local density of dark matter
arXiv:1111.5122 · doi:10.1051/epjconf/20121901008
Abstract
We study the systematic problems in determining the local dark matter density $Ï_{dm}(R_\odot)$ from kinematics of stars in the Solar Neighbourhood, using a simulated Milky Way-like galaxy. We introduce a new unbiased method for recovering $Ï_{dm}(R_\odot)$ based on the moments of the Jeans equations, combined with a Monte Carlo Markov Chain technique and apply it to real data. ov
