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 Astronomy at Gresham College from 2015 to 2019.

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]
Sandra Moore Faber is an American astrophysicist known for her research on the evolution of galaxies. She is the University Professor of Astronomy and Astrophysics at the University of California, Santa Cruz, and works at the Lick Observatory. She has made discoveries linking the brightness of galaxies to the speed of stars within them and was the co-discoverer of the Faber–Jackson relation. Faber was also instrumental in designing the Keck telescopes in Hawaii.
The American Astronomical Society is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community.
Martin John Rees, Baron Rees of Ludlow, is a British cosmologist and astrophysicist. He is the fifteenth Astronomer Royal, appointed in 1995, and was Master of Trinity College, Cambridge, from 2004 to 2012 and President of the Royal Society between 2005 and 2010.
John David Barrow was an English cosmologist, theoretical physicist, and mathematician. He served as Gresham Professor of Geometry at Gresham College from 2008 to 2011. Barrow was also a writer of popular science and an amateur playwright.
Michael S. Turner is an American theoretical cosmologist who coined the term dark energy in 1998. He is the Rauner Distinguished Service Professor Emeritus of Physics at the University of Chicago, having previously served as the Bruce V. & Diana M. Rauner Distinguished Service Professor, and as the assistant director for Mathematical and Physical Sciences for the US National Science Foundation.
(Geoffrey) Michael Rowan-Robinson is an astronomer, astrophysicist and Professor of Astrophysics at Imperial College London. He previously served as head of the astrophysics group until May 2007 and from 1981 to 1982, and as Gresham Professor of Astronomy.
Richard Salisbury Ellis is Professor of Astrophysics at the University College London. He previously served as the Steele Professor of Astronomy at the California Institute of Technology (Caltech). He was awarded the 2011 Gold Medal of the Royal Astronomical Society, in 2022 the Royal Medal of the Royal Society and in 2023 the Gruber Prize in Cosmology.
The position of Savilian Professor of Astronomy was established at the University of Oxford in 1619. It was founded by Sir Henry Savile, a mathematician and classical scholar who was Warden of Merton College, Oxford, and Provost of Eton College. He appointed John Bainbridge as the first professor, who took up his duties in 1620 or 1621.
Margaret J. Geller is an American astrophysicist at the Center for Astrophysics | Harvard & Smithsonian. Her work has included pioneering maps of the nearby universe, studies of the relationship between galaxies and their environment, and the development and application of methods for measuring the distribution of matter in the universe.
Robert P. Kirshner is an American astronomer, Chief Program Officer for Science for the Gordon and Betty Moore Foundation, and the Clownes Research Professor of Science at Harvard University. Kirshner has worked in several areas of astronomy including the physics of supernovae, supernova remnants, the large-scale structure of the cosmos, and the use of supernovae to measure the expansion of the universe.
