Institute Community and Equity Officer (ICEO); Professor of Physics

On July 1, 2013, Edmund Bertschinger was appointed as Institute Community and Equity Officer.  Read the MIT News release for more information.

Professor Edmund Bertschinger’s group develops and applies analytical, computational, and statistical methods to improve our understanding of gravitation and cosmology.  Their main research topics are:

  • Dark matter: improving our understanding of how it clusters to form galaxies and larger structures, investigating its detectability in the cosmos and laboratory
  • Dark energy: phenomenology of theories of dark energy and their cosmological tests
  • Testing general relativity, especially in cosmology
  • Developing consistent modified gravity theories and developing observational tests of them
  • Other topics in theoretical physics and cosmology, e.g. cosmological perturbation theory, scalar fields and neutrinos in cosmology, parallel computation

Group members:  graduate student David Hernandez and postdoc Chanda Prescod-Weinstein

Potential and density for a mixed cold+hot dark matter model with Omega_hot = 0.2. A slice of size 50 Mpc/h is shown. Upper left: Newtonian potential at the end of inflation. Upper right: potential at the end of recombination. Lower left: density at the end of recombination. Lower right: density at redshift 0.
