One source of these phenomena is stellar collapse such as that which occurs in type II supernovae,  and in 1974 Hulse and Taylor inferred the existence of these phenomena by studying the energy (*)  loss from a rotating pulsar.

Most famously sought by the LIGO experiment, for 10 points— identify these phenomena which represent traveling wave solutions to the Einstein field equations.
