Visualization of the diverse topologies of magnetic field lines around cold CGM clouds. The two panels show slices of the Voronoi mesh centered around two clouds, both oriented such that their mean velocity vector (i.e., the direction of motion) are to the right, the positive x-axis direction. Cells that belong to the cloud (interface layer) are outlined using black (white) lines. Streamlines show the direction of magnetic field lines. The three numbers at the top of each image correspond to the mean magnetic curvature of the cloud interface (κ), the overdensity (δ), and relative velocity (v_rel) between the cloud and the interface layer. While the left cloud is threaded by magnetic fields in a region of the background CGM that has particularly uniform field orientation, the magnetic fields in the right panel begin to respond to the motion of the cloud. This diversity is captured by the different values of κ.
