George Petros Efstathiou (born September 2, 1955 in London ) is a British astrophysicist.

Life

Efstathiou studied from 1973 at Oxford University (bachelor's degree in physics 1976) and the University of Durham , where he received his doctorate in astronomy in 1979. In 1979/80 he was a post-doctoral student at the University of California, Berkeley and then at the Institute for Astronomy at Cambridge University . From 1988 he was Savilian Professor of Astronomy at Oxford University and from 1988 to 1994 head of the Astrophysics Department at Oxford. From 1997 he was Professor of Astrophysics at the University of Cambridge and from 2004 to 2008 Director of the Institute for Astronomy in Cambridge. From 2008 he is director of the Kavli Institute for Cosmology in Cambridge.

Efstathious studies of the effect of (cold) dark matter on structure formation in the early universe go back to 1980. He published the first numerical simulations in 1981, the first calculations of the CMB anisotropy in CDM ( cold dark matter ) scenario in 1984, followed by more detailed studies with Carlos Frenk , Marc Davis and Simon White . In 1990 he found the first indications of inconsistencies in a CDM scenario with vanishing cosmological constants from the analysis of the data from the APM Galaxy Survey. Efstathiou was also involved in the 2dFGRS ( 2dF Galaxy Redshift Survey ) (which was based on the APM Galaxy Survey and carried out by the Australian Astronomical Observatory from 1997 to 2001), which also confirmed a non-vanishing cosmological constant. Efstathiou is also a leader in ESA's Planck Space Telescope mission.

In 1990 he received the Maxwell Medal and in 2005 the Dannie Heineman Prize for Astrophysics with Simon White . In 2011 he received the Gruber Prize for Cosmology with Marc Davis, Carlos Frenk and Simon White for the development of Cold Dark Matter models of the early universe. In 1994 he became a Fellow of the Royal Society . He is a Fellow of the Institute of Physics and the Royal Astronomical Society (1983 to 2010). In 2015 he received the Hughes Medal from the Royal Society.
