The MUSIC of CLASH: predictions on the concentration-mass relation

Meneghetti, M., Rasia, E., Vega, J. et al.

Understand

We present the results of a numerical study based on the analysis of the MUSIC-2 simulations, aimed at estimating the expected concentration-mass relation for the CLASH cluster sample.

  • We study nearly 1400 halos simulated at high spatial and mass resolution, which were projected along many lines-of-sight each.
  • We study the shape of both their density and surface-density profiles and fit them with a variety of radial functions, including the Navarro-Frenk-White, the generalised Navarro-Frenk-White, and the Einasto density profiles.
  • We derive concentrations and masses from these fits and investigate their distributions as a function of redshift and halo relaxation.
