The formation and evolution of galaxies bridges fundamental physics from small to large scales. As such, all internal and external effects that shape a galaxy’s evolution together determine its present-day properties. But the individual physical processes in some cases may leave distinctive observational signatures, for example bursts of star formation or (temporary) quenching, the formation of bulges and bars, changes in metallicity or age gradients, warps, outflows and much more.

Since their detection in 1967, neutron stars have been studied extensively at radio wavelengths as well as higher energies. Some neutron stars are known to spin rapidly and reach very large magnetic fields at their surface. Such fast rotating neutron stars are referred to as pulsars. They have a co-rotating magnetosphere and generate emission over large parts of the electromagnetic spectrum through processes that are not yet understood in detail. Some pulsars are not equally bright in every rotation. Instead they sporadically produce giant pulses of extremely bright radio emission.
