Joseph Hooton Taylor

Joseph Hooton Taylor, Jr. (March 29th 1941 -) is a American astrophysicist, Nobel Prize of physics in 1993 divided with Russell Alan Hulse for “its discovery of a new type of Pulsar opening the way with new possibilities for the study of the Gravitation. ”

Its beginnings

Taylor is born with Philadelphia wire from Joseph Hooton Taylor, Sr., and Sarah Evans Taylor, all two having roots Quaker since several generations. He studies with the Haverford College, B.A. of Physique in 1963 then with the Université Harvard, Ph.D of Astronomie in 1968. After a short research task in Harvard, Taylor obtains a post of professor with the Université of Massachusetts and assisting director of the Five College Radio operator Astronomy Observatory. The thesis of Taylor relates to the lunar Occultation S. During the same period Jocelyn Bell discovers the first Pulsar radio with Cambridge.

Discovered first binary pulsar

Taylor uses the telescopes of the National Radio operator Astronomy Observatory in Virginia-Western and takes part in discovered of first pulsars apart from those already located in Cambridge. Since he worked on all the aspects of the Astrophysique of pulsars. In 1974 Taylor and Hulse discover first binary pulsar, PSR B1913+16, during a program of observation of the Radiotélescope of Arecibo in the island of Puerto Rico. Although the fact is not included/understood at the time it is also the first pulsar recycled , a neutron star whose rotation was accelerated by a transfer of its mass on its star companion.

According to the theory of the General relativity the orbit of a binary system is slowly modified by the emission of gravitational Onde. The theory predicts with precision these modifications and over one period of thirty years Taylor and his/her colleagues make measurements which correspond to the theory with a precision lower than 1%. Several other binary pulsars nowadays are known and of independent measurements the results of Taylor confirm.

Continuation of its career

In 1980 it moves with the Université of Princeton or he becomes professor James Smith McDonnell of physics, he is also during six years senior of this university.

Rewards

Taylor used first binary pulsar to make a precise checking of the forecasts of the General relativity. Working with his/her colleague Joel Weisberg, Taylor confirms the existence of gravitational Onde in quantity and characteristics in conformity with the theory. Taylor and Hulse divide a Nobel Prize for the discovery of this pulsar.

Apart from this Nobel, Taylor receives the Prix Dannie Heineman for astrophysics of the American Astronomical Society in 1980, the Médaille Henry Draper National Academy off Sciences in 1985, the Médaille Albert Einstein in 1991, the Prix Wolf of physics in 1992 and others. It also takes part at many work groups and committees.

Radio ham

Taylor is also known like Radioamateur in the using field of the communications of the weak signals such as EME or the use of atmospheric phenomena like reflectors of waves.
