Dwarf galaxies and globular clusters may be an important source of hypervelocity stars, especially those that are metal poor, low mass, and reside in the Milky Way halo.

Rebecca Lin et al 2023 ApJ 945 115

Analysis of nearly 62,000 giant pulses from the Crab Nebula pulsar suggests that the plasma emitting the pulse is moving relativistically; relativistic motion may be necessary for giant pulses in general.
