Radio ham contributed to Detection of Gravitational Waves

Radio amateur Dr. Joe Taylor K1JT and Dr. Russell Hulse won the Nobel
Prize in Physics in 1993 'for the discovery of a new type of pulsar, a
discovery that has opened up new possibilities for the study of
gravitation'

A New York Times article about the Detection of Gravity Waves notes
Joe Taylor's contribution:

In 1978, the radio astronomers Joseph H. Taylor Jr. [K1JT] and Russell
A. Hulse, then at the University of Massachusetts Amherst, discovered
a pair of neutron stars, superdense remnants of dead stars, orbiting
each other. One of them was a pulsar, emitting a periodic beam of
electromagnetic radiation. By timing its pulses, the astronomers
determined that the stars were losing energy and falling closer
together at precisely the rate that would be expected if they were
radiating gravitational waves.

In awarding the Nobel Prize in 1993 The Royal Swedish Academy of Sciences said:

What was new about the Hulse-Taylor pulsar was that, from the
behaviour of the beacon signal, it could be deduced that it was
accompanied by an approximately equally heavy companion at a distance
corresponding to only a few times the distance of the moon from the
earth. The behaviour of this astronomical system deviates greatly from
what can be calculated for a pair of heavenly bodies using Newton's
theory. Here a new, revolutionary "space laboratory" has been obtained
for testing Einstein's general theory of relativity and alternative
theories of gravity. So far, Einstein's theory has passed the tests
with flying colours. Of particular interest has been the possibility
of verifying with great precision the theory's prediction that the
system should lose energy by emitting gravitational waves in about the
same way that a system of moving electrical charges emits
electromagnetic waves.
