Joseph Hooton Taylor Jr. (born March 29, 1941) is an American

Nobel Prize laureate in Physics[1] for his discovery with Russell Alan Hulse of a "new type of pulsar
, a discovery that has opened up new possibilities for the study of gravitation."

Early life and education

Taylor was born in

Moorestown Township, New Jersey, where he excelled in math.[2]

He received a B.A. in physics at Haverford College in 1963, and a Ph.D. in astronomy at Harvard University in 1968. After a brief research position at Harvard, Taylor went to the University of Massachusetts Amherst, eventually becoming Professor of Astronomy and Associate Director of the Five College Radio Astronomy Observatory.

Taylor's thesis work was on

Jocelyn Bell (who is also a Quaker) discovered the first radio pulsars with a telescope near Cambridge, England
.

Career

Taylor immediately went to the National Radio Astronomy Observatory's telescopes in Green Bank, West Virginia, and participated in the discovery of the first pulsars discovered outside Cambridge. Since then, he has worked on all aspects of pulsar astrophysics.

In 1974, Hulse and Taylor discovered the first

PSR B1913+16 after its position in the sky, during a survey for pulsars at the Arecibo Observatory in Puerto Rico. Although it was not understood at the time, this was also the first of what are now called recycled pulsars: Neutron stars
that have been spun-up to fast spin rates by the transfer of mass onto their surfaces from a companion star.

The orbit of this binary system is slowly shrinking as it loses energy because of emission of

General Theory of Relativity
, and over a thirty-year period Taylor and his colleagues have made measurements that match this prediction to much better than one percent accuracy. This was the first confirmation of the existence of gravitational radiation. There are now scores of binary pulsars known, and independent measurements have confirmed Taylor's results.

Taylor has used this first

Faculty
. He retired in 2006.

Amateur radio

Joe Taylor first obtained his

amateur radio license as a teenager, which led him to the field of radio astronomy. Taylor is well known in the field of amateur radio weak signal communication and has been assigned the call sign K1JT by the FCC. He had previously held the callsigns K2ITP, WA1LXQ, W1HFV, and VK2BJX (the latter in Australia).[3]

His amateur radio accomplishments have included mounting an 'expedition' in April 2010 to use the

moonbounce with Amateurs around the world using voice, Morse code, and digital communications.[3]

He has been active in developing several computer programs and communications protocols, including WSPR and WSJT ("Weak Signal/Joe Taylor"), a software package and protocol suite that utilizes computer-generated messages in conjunction with radio transceivers to communicate over long distances with other amateur radio operators.

WSJT is useful for passing short messages via non-traditional radio communications methods, such as

meteor scatter and other low signal-to-noise ratio paths. It is also useful for extremely long-distance contacts using very low power
transmissions.

Honors and awards

Taylor was among the first group of

MacArthur Fellows. He has served on many boards, committees, and panels, co-chairing the Decadal Panel of that produced the report Astronomy and Astrophysics in the New Millennium that established the United States
's national priorities in astronomy and astrophysics for the period 2000–2010. He was a guest of honor in the 2009 International Physics Olympiad.
