Baryon and Sunyaev-Zel'dovich effect properties of MareNostrum and MultiDark simulated clusters (MUSIC)

TL;DR

This paper presents initial findings from the MUSIC project, analyzing baryon content and Sunyaev-Zel'dovich scaling relations in over 400 simulated galaxy clusters from two large dark matter simulations.

Contribution

It introduces the MUSIC dataset with high-resolution resimulated clusters including radiative physics, providing new insights into baryon and SZ properties.

Findings

Baryon content varies with cluster mass and physics included.

Sunyaev-Zel'dovich scaling relations are characterized for the simulated clusters.

The dataset enables detailed studies of cluster physics and cosmology.

Abstract

We report the first results of the MUSIC project. It consists of two data sets of resimulates clusters extracted from two large dark matter only simulations: Marenostrum Universe and Multidark. In total, the MUSIC contains more than 400 clusters resimulated with high resolution both with radiative and non-radiative physics included. Here we present the first results on the properties of the baryon content and the Sunyaev Zeldovich scaling relations.
