Rotation of the Milky Way halo in the solar neighborhood based on GAIA DR3 catalog

The rotation of the Milky Way halo in the solar neighborhood is investigated using kinematic data from the GAIA DR3 catalog for RR Lyrae variable stars with parallax errors of less than 20%. Two criteria were used for selecting halo stars — kinematic and spatial. In both approaches, we confirm the existence of weak rotation of the halo in the direction opposite to the rotation of the Galactic disk with velocities of 4.08 ± 2.19 km/s for the kinematic criterion and 9.49 ± 2.59 km/s for the spatial criterion.
