Sloshing of the Magnetized Cool Gas in the Cores of Galaxy Clusters

Set Characteristics

  • Simulation type: AMR
  • Box size: L = 2 Mpc
  • Finest cell size: \(\Delta{x}_{\rm min}\) = 0.977 kpc
  • Primary cluster mass: \(M_{200} = 10^{15}~M_{\odot}\)

Notes

  • Projected X-ray emissivities are computed using an APEC model (see the yt documentation on X-ray emission fields for details). There is no metallicity field in these simulations; hence for computing X-ray emissivities for projections a spatially constant metallicity of \(Z = 0.3~Z_\odot\) is assumed.
  • The data presented here are not from the original simulations presented in the relevant paper but are improved versions with higher spatial resolution and improved treatment of gravity. For details on the latter see Roediger & ZuHone 2012.
  • For each simulation, the main cluster is fixed at r = [0, 0, 0] kpc. A tab-separated ASCII table containing the subcluster position, velocity, and acceleration as a function of time may be found here.

Cosmology

Note

For non-cosmological simulations such as this one, a cosmology and redshift are assumed for the purposes of calculating distance and redshift-dependent quantities.

  • \(\Lambda{\rm CDM}\) cosmology
  • \(H_0 = 71~{\rm km~s^{-1}~Mpc^{-1}}\)
  • \(\Omega_m = 0.27\)
  • \(\Omega_\Lambda = 0.73\)
  • \(z = 0.05\) for all epochs

Simulations

For the following simulations, \(\beta = p_{\rm th}/p_B\).
