Abstract
Recent STEREO observations reveal that large scale downstream magnetic
oscillations are quite typical for quasi-perpendicular low-Mach number
shock. It has been shown recently, both in theory and 1D hybrid
simulations, that these oscillations are, most plausibly, related to the
collisionless relaxation of the downstream gyrating ion distributions. A
number of observed shocks exhibit clear deviations from
one-dimensionality. We extend our previous analysis to two-spatial
dimensions by using 2D hybrid code, which allows studying the
inhomogeneity along the shock front. We investigate in detail the
formation of gyrating distributions in this 2D geometry and further
relaxation of these distributions accompanying with generation of
magnetic oscillations.
