Jim Peebles

Philip James ( "Jim" ) Edwin Peebles ( born April 25, 1935 in Winnipeg, Manitoba ) is a leading Canadian cosmologist.

Life and work

Peebles studied at the University of Manitoba ( BA 1958) and received his doctorate in 1962 at Robert Dicke ( under whose influence he moved from particle physics to cosmology ) at Princeton University, where he remained for his entire career over and is now Professor Emeritus. He is currently the Albert Einstein Professor of Science Emeritus (as successor of thickness).

He made valuable contributions to the Big Bang model, and said in thickness and others in the 1960s, the 3K background radiation ahead, as already George Gamow and colleagues in the 1940s, but their prediction was forgotten.

Peebles is a leading authority in cosmology and dealt with the issue at some length, as this is " in fashion" was far from. He made ​​important contributions to Bigbang - nucleosynthesis (frequency of light elements such as helium, which in 1966 Bigbang theory confirmed ), the structure formation in the early universe ( Statistical distribution of the clustering of galaxies and clusters of galaxies, which are determined from the 1970s precisely with computers could ) and the issues of dark matter or dark energy. He examined the existence of dark matter in the late 1970s with Jerry Ostriker ( Princeton ) and had large amounts of dark matter in the halos of galaxies after. In the 1980s, however, he was skeptical of his opinion too easily assumed assumption of dark matter in cosmological models for galaxy formation and looked for alternatives. Today he sees but the Cold Dark Matter (CDM ) models well confirmed, even if he still some open issues, such as the phenomenon of bubbles (void ) in the galaxy distribution looks. He also pointed out early in the 1980s the need for a cosmological constant, but sees this as a foreign body in the present theory building.

His book, Principles of Physical Cosmology is a standard work, which contributed much to the establishment of cosmology as an important research direction.

A minor planet named after him ( 18242 Peebles ).
