Two galaxies, each containing a
black hole at their centre, merge. The two back
holes orbit one another at the centre of the merged
galaxy, sending out gravity waves as they perturb
spacetime in their vicinity. These gravity waves
eventually reach our Galaxy, the Milky Way, where
they modulate the signals from pulsars. The
apparent pulsar period is alternately red-shifted
and blue-shifted as the wave passes over the pulsar
and the Earth.

Formation of the double pulsar system. The first-formed pulsar is 'spun up' to become a rapidly rotating 'millisecond pulsar' by matter accreting from its red giant companion.
Evolution animation: How the double pulsar system formed. The double pulsar probably formed from a pair of massive stars orbiting each other. (This animation does not show the orbital motion.) The more massive star ended its life first, swelling to become a red giant and then exploding as a supernova, its core forming a pulsar. The second star entered the red giant phase later: when it did, matter from this star was transferred onto its pulsar companion, spinning that up to become a fast-rotating "millisecond" pulsar. The red giant then went supernova, forming the second, slower, pulsar.
