Dark matter in the Milky Way: Measurements up to 3 kpc from the Galactic plane above Sun's location

We are probing the gravitational force perpendicular to the Galactic plane at the position of the Sun with a sample of red giants whose measurements are taken from the DR3-Gaia catalogue. Measurements far out of the Galactic plane up to 3.5 kpc allow us to determine directly the total mass density where dark matter is dominant, while stellar and gas densities are very low. In a complementary way, we are also using a new determination of the local baryonic mass density to help us determine the density of dark matter in the Galactic plane at the solar position. We obtain for the local mass density of dark matter ρdm=0.0128±0.0008 M_ pc⁻³ = 0.486 ±0.030 Gev cm⁻³, for the flattening of the gravitational potential of the dark halo q_φ,h=0.843±0.035, and for its density q_ρ,h=0.781±0.055.
