Joseph Ivor Silk FRS (born 3 December 1942) is a British-American [citation needed] astrophysicist. He was the Savilian Chair of Astronomy at the University of Oxford from 1999 to September 2011.
He is an Emeritus Fellow of New College, Oxford[2] and a Fellow of the Royal Society (elected May 1999). He was awarded the 2011 Balzan Prize for his works on the early Universe.[3] Silk has given more than two hundred invited conference lectures, primarily on galaxy formation and cosmology.
He was educated at Tottenham County School (1954–1960) and went on to study Mathematics at the University of Cambridge (1960–1963), followed by a diploma in astrophysics at the University of Manchester under the supervision of Roger Jennison.[4] He obtained his PhD in Astronomy from Harvard in 1968, under the direction of David Layzer.[4] Silk took up his first post at Berkeley in 1970, and the Chair in Astronomy in 1978. Following a career of nearly 30 years there, Silk returned to the UK in 1999 to take up the Savilian Chair of Astronomy at the University of Oxford. He is currently Professor of Physics at the Institut d'astrophysique de Paris, Université Pierre et Marie Curie, Homewood Professor of Physics and Astronomy at Johns Hopkins University (since in 2010), and was Professor of AstronomyatGresham College from 2015 to 2019.[5]
The structure of the cosmic microwave background anisotropies is principally determined by two effects: acoustic oscillations and diffusion damping. The latter is also called collisionless or Silk damping after Joseph Silk.
Silk has over 900 publications, nearly 200 as first author, of which 3 have been cited over 1000 times, over 50 have been published in Nature and 12 in Science.[8]
In 2011, Silk delivered a talk, "The Creation of the Universe," at the first Starmus Festival in the Canary Islands. The talk was subsequently published in the book Starmus: 50 Years of Man in Space.[9]
