Joseph Ivor Silk FRS (born 3 December 1942) is a British-American 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 and a Fellow of the Royal Society (elected May 1999). He was awarded the 2011 Balzan Prize for his works on the early Universe. Silk has given more than two hundred invited conference lectures, primarily on galaxy formation and cosmology.
Biography
He was educated at Tottenham County School (1954–1960) and went on to study Mathematics at the University of Cambridge (1960–1963). He obtained his PhD in Astronomy from Harvard in 1968. 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 Professor of Astronomy at Gresham College from 2015 to 2019.
Silk damping
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.
