  Antony Hewish - Wikipedia, the free encyclopedia
Antony Hewish (born Fowey, Cornwall, May 11, 1924) is a British radio astronomer who won the Nobel Prize for Physics in 1974 (together with fellow radio-astronomer Martin Ryle) for his work on the development of radio aperture synthesis and its role in the discovery of pulsars.
Hewish made both practical and theoretical advances in the observation and exploitation of the apparent scintillations of radio sources due to their radiation impinging upon plasma.
Hewish was professor of radio astronomy at the Cavendish Laboratory from 1971 to 1989, and head of the MRAO from 1982 to 1988.

Antony Hewish, född 1924, engelsk radioastronom och nobelpristagare.
Efter utbildningen vid University of Cambridge anslöt sig Hewish 1946 till den grupp av radioastronomer som leddes av Sir Martin Ryle.
Hewish insåg betydelsen av observationen och lyckades fastställa att signalerna inte var interferens från någon källa på jorden utan måste komma från en dittills okänd typ av stjärna.

 Antony Hewish Biography / Biography of Antony Hewish History of Scientific Discovery Biography
Hewish examined how radio sources were received on the Earth; often these sources were disturbed by ionized gas in the Earth's atmosphere or by interstellar disturbances.
In 1965 Hewish designed a new kind of radio telescope to detect quasars and assigned Jocelyn Bell, one of his graduate students, the task of bringing the telescope on line.
Hewish has remained active in his field, and in 1998 was elected a fellow of the Institute of Physics.

While pursuing her PhD at Cambridge University, Jocelyn Bell's advisor was Antony Hewish, a radio astronomer.
Hewish and his graduate students in 1967 completed a radio telescope specially designed to observe the scintillation (twinkling) of stars, particularly quasars.
Bell and Hewish's discovery was the first known evidence for this, and the pulsing signal source became known as a pulsar.

 C.S.S.L. General Information
Hewish will talk about these new frontiers in radioastronomy as well as the design and construction of a new powerful radio telescope by Cambridge’s Cavendish Laboratory that is expected to be a boon in the effort to learn more about the origins of our own galaxy.
Hewish and Bell’s discovery served as the first evidence of this phenomenon, and the signal source became known as a pulsar.
Hewish’s numerous honors and awards include the Holweck Medal and Prize from the Société Française de Physique; the Hughes Medal of the Royal Society; the Michelson Medal from the Franklin Institute; the Dellinger Medal from the International Union of Radio Science; and the Eddington Medal from the Royal Astronomical Society.

 Wikipedia: Antony Hewish
Antony Hewish (born Fowey, Cornwall, May 11, 1924) is a British radio astronomer who won the Nobel Prize for Physics in 1974 for his role in the discovery of pulsars.
This led him to propose, and secure funding for, the construction of a large array radio telescope at Cambridge in order to conduct a high resolution radio sky survey.
The Nobel award to Hewish without the inclusion of Bell as a co-recipient was controversial, and was roundly condemned by Hewish's fellow astronomer Fred Hoyle.

 Hewish Family Crest
The forbears that initially held the name Hewish once lived in one of the various places named Huish in the English counties of Devonshire, Dorset, Somerset, and Wiltshire.
The surname Hewish belongs to the category of habitation names, which are derived from pre-existing names for towns, villages, parishes, or farmsteads.
In the Hewish coat of arms as in all coat of arms the crest is only one element of the full armorial achievement.

 Cambridge Interferometer - Wikipedia, the free encyclopedia
The Cambridge Interferometer was a radio telescope interferometer built by Martin Ryle and Antony Hewish in the early 1950s to the west of Cambridge (between the Grange Road football ground and the current Cavendish Laboratory).
The interferometer consisted of an array of 4 fixed elements to survey the sky, and produced the 2C catalogue of radio sources at 81.5 MHz, and the 3C catalogue of radio sources at 159 MHz discovering some of the most interesting astronomical objects known.
Martin Ryle and Antony Hewish received the Nobel Prize for Physics in 1974 for this and other related work.

 Jocelyn Bell Burnell - Wikipedia, the free encyclopedia
At Cambridge, she worked with Hewish and others to construct a radio telescope for using interplanetary scintillation to study quasars, which had recently been discovered (interplanetary scintillation allows compact sources to be distinguished from extended ones).
Although she (famously) did not share the Nobel Prize with Hewish for her discovery, she has been honored by many other organizations.
She has won the Oppenheimer Prize, the Michelson Medal of the Franklin Institute, the Beatrice M. Tinsley Prize of the American Astronomical Society, the Magellanic Premium of the American Philosophical Society, the Jansky Lectureship of the National Radio Astronomy Observatory, and the Herschel Medal of the Royal Astronomical Society.

While directing a research project at the Mullard Radioastronomy Observatory at Cambridge in 1967, Hewish recognized the significance of an observation made by a graduate assistant, Jocelyn Bell.
He determined that the regularly patterned radio signals, or pulses, that Bell had detected were not caused by earthly interference or, as some speculated, by intelligent life forms trying to communicate with distant planets but rather were energy emissions from certain stars.
For this work in identifying pulsars as a new class of stars, he was awarded jointly with Ryle the Nobel Prize for Physics in 1974, the first time the prize had been given for observational astronomy.

 Jocelyn Bell
Lead by Professor Antony Hewish, Cambridge graduate student Jocelyn Bell was surveying the sky for scintillation phenomena due to interplanetary plasma in a certain radio frequency range.(Chiu, p.965) Among the expected random noises, Bell noted a repeating signal.
However, in 1974, it was Antony Hewish who received a Nobel Prize in Physics for "the discovery of pulsars".(Martens, 1996) Despite considerable documentation to prove Bell actually discovered the pulsar, the Nobel Foundation ignored her and gave the prestigious award to Hewish.
Working as a graduate student at Cambridge University, Jocelyn Bell was the first to discover this amazing phenomenon, but in spite of documentation attesting to her principal role, the credit for the work and discovery went to her professor Antony Hewish in the form of a Nobel Prize in Physics in 1974.

To map distant radio sources, he developed a technique called aperture synthesis, which provided tremendously increased resolving power for radio telescopes and was used to locate the first pulsar.

Before 1950, Hewish used radio telescopes mainly to study the solar atmosphere.
Before the discovery of pulsars, Hewish examined the fluctuation in such sources of the intensity of the radiation (the scintillation) resulting from disturbances in ionized gas in the Earth's atmosphere, within the Solar System, and in interstellar space.

She was a graduate student at that time, and although her supervisor Antony Hewish later received a Nobel Prize for the discovery, Jocelyn Bell was not included.
Hewish and his colleagues had not shared their excitement with anyone outside a tight-knit group.
The Bell discovery was made while Bell, Hewish, and Ryle were at Cambridge University (UK), and the astronomer Martin Rees, who was of the faculty at Cambridge at that time, writes of Jocelyn Bell as follows: "Jocelyn Bell received less than her fair share of credit for the discovery of pulsars.
