Marc Kamionkowski

from Wikipedia, the free encyclopedia

Marc Kamionkowski (* 1965 in Cleveland , Ohio ) is an American theoretical astrophysicist who studies supersymmetric dark matter , cosmology and astroparticle physics.

Life

Kamionkowski graduated from Washington University with a bachelor's degree in 1987 and received his PhD from the University of Chicago in 1991 . As a post-doctoral student , he was at the Institute for Advanced Study . In 1994 he became an assistant professor at Columbia University . From 1999 he was a professor at Caltech , from 2006 as Robinson Professor for theoretical physics and astrophysics. In 2011 he became a professor at Johns Hopkins University .

He predicted signatures and observation marks of supersymmetrical dark matter (in accelerators, in direct observation, in neutrino telescopes and cosmic rays). In 1990, together with Kim Griest, he derived an upper limit of 340 TeV for particles of dark matter from quantum mechanics.

Another focus of his work is the cosmic microwave background (CMB). In 1993, together with David Spergel and Naoshi Sugiyama, he derived a method for drawing conclusions about the geometry of the universe from temperature anisotropies. They were thus also pioneers in the application of the Fisher matrix in parameter estimation in astrophysics. In 1996, together with Arthur Kosowsky and Albert Stebbins, he predicted that gravitational waves from the Big Bang left signatures in the polarization of the CMB, which is being investigated in Bicep , the Planck space telescope and other experiments and was a current research topic in 2014.

In 2003 he designed the Big Rip model of the end of the universe with Robert Caldwell and Nevin Weinberg .

With John March-Russell he investigated violation of global symmetries by quantum gravity in 1992 and with Arthur Lue and Limin Wang in 1999 parity violation in the CMB.

Honors and memberships

In 2015 he received the Dannie Heineman Prize for Astrophysics with David Spergel for her contributions to the analysis of fluctuations in the CMB, the Ernest Orlando Lawrence Prize in 2006 and the Helen B. Warner Prize in 1998 . In 2010 he was Miller Visiting Professor at Berkeley.

From 1996 to 1998 he was a Sloan Research Fellow , became a Fellow of the American Academy of Arts and Sciences in 2013 and of the American Physical Society in 2008 . Kamionkowski is a member of the American Association for the Advancement of Science and has been a member of the National Academy of Sciences since 2019 .
