Neutron stars galore. Each point-like source in this x-ray image of the Antennae Galaxies is a neutron star or black hole devouring a companion star. Space is strongly warped near these compact objects, so any nearby magnetic fields are likely to be distorted as well. The tension in bent field lines may in turn reduce the curvature of space.
