| Abstract: |
We present the numerical implementation
of run-time injection of Cosmic Rays energy, their spatial
advection and their dynamical feedack on baryonic gas in the cosmological grid
code ENZO.
We discuss the results of its application to large-scale simulations showing that the CR energy inside clusters of galaxies is small compared to
the gas energy (less than a few percent), while the ratio
is larger near the accretion regions of clusters and filaments (∼ 0.1 – 0.3). CR feedback has a small, but significant
impact on the X-ray emission and Sunyaev-Zeldovich effect from clusters. |
