Limits on the local dark matter density


Garbari, S; Read, J I; Lake, G (2012). Limits on the local dark matter density. EPJ Web of Conferences, 19:01008.

Abstract

We study the systematic problems in determining the local dark matter density ρ<roman>dm</roman>(Rsun) from kinematics of stars in the Solar Neighbourhood, using a simulated Milky Way-like galaxy. We introduce a new unbiased method for recovering ρ<roman>dm</roman>(Rsun) based on the moments of the Jeans equations, combined with a Monte Carlo Markov Chain (MCMC) technique and apply it to real data [1].
