Numerical simulation of Structure formation with cold dark matter (left) and two-component flavor-mixed dark matter (right). Simulations were carried out using the Arepo code at the Advanced Computing Facilities, University of Kansas.

About (back to top)
The Center for Relativity and Cosmology at ÁùºÏ±¦µä seeks to answer fundamental questions about the universe ranging from the nature of the relativistic jets emanating from supermassive black holes at the center of galaxies to the nature of Dark Matter. The faculty in the center also explores how quantum matter interacts with gravity, impacting gravitational collapse and astrophysical objects. We have several ongoing projects in astrophysics, cosmology, relativity, quantum field theory, differential geometry and geometric analysis, and has active collaborations with general relativists, cosmologists, and mathematical physicists.
