The Magneticum Pathfinder simulations are complemented with a set of additional simulations, which allow to test the effect of physical sub-grid models on the evolution of galaxies and galaxy clusters as well as to allow to include the effects of the prominent structures in the local universe on observables.         

Local Universe Simulation

Coruscant

Coruscant is a cosmological re-simulation of the local universe based on initial conditions reconstructed from the 1.2 muJ IRAS full sky survey. This simulation is designed to represent the observed local neighborhood out ca. 110Mpc and makes it possible to identify prominent haloes from the simulations with real observed galaxy cluster. This simulaion is available including various physical processes and is also part of the PLANCK sky mode. There is a version of the simulation available which includes exactly the same sub-grid models than used in the Magneticum Pathfinder set of simulations.

Cluster re-simulations

Dianoga Cluster

With the aim to understand the formation of galaxy clusters and especially the impact of the gas physics and the feedback processes involved on the evolution the inra cluster medium, we performed high-resolution zoom simulations of a set of mass limited galaxies clusters selected from a large cosmological box (Gpc in size) describe with the standard WMAP-7 LCDM cosmological parameters. We produced 24 Lagrangian regions etracted around the most massive clusters. For each of these regions, initial conditions have been re-generated by increasing mass resolution and adding high-frequency modes, while progressively degrading resolution in outer regions. For each cluster, initial conditions have been generated at the level of the hr resolutions of the Magenticum Pathfinder simulations. These simulations are used to test the implementation of new physical modules and to quantify the impact of the sub-grip models on the intra cluster medium.

Galaxy re-simulation

Dianoga Galaxies

With the aim to understand the formation of galaxies and especially the impact of the gas component and the feedback on the evolution of elliptical galaxies in various cosmological environments, we performed high-resolution zoom simulations of galaxies selected from a large cosmological box (Gpc in size). These simulations are also used to test the parameters of the sub-grid models used in the Magneticum Pathfinder simulations. The image on the left shows a massive galaxy forming inside a void structure at present day.
