  bibo_abstract:
  - Cold dark matter (CDM) hierarchical structure formation models predict the existence
    of large-scale accretion shocks between the virial and turnaround radii of clusters
    of galaxies. Kocsis et al. suggest that the Sunyaev–Zel'dovich signal associated
    with such shocks might be observable with the next generation radio interferometer,
    ALMA (Atacama Large Millimeter Array). We study the three-dimensional distribution
    of accretion shocks around individual clusters of galaxies drawn from adaptive
    mesh refinement (AMR) and smoothed particle hydrodynamics simulations of ΛCDM
    (dark energy dominated CDM) models. In relaxed clusters, we find two distinct
    sets of shocks. One set ("virial shocks"), with Mach numbers of 2.5–4, is located
    at radii 0.9–1.3 Rvir, where Rvir is the spherical infall estimate of the virial
    radius, covering about 40%–50% of the total surface area around clusters at these
    radii. Another set of stronger shocks ("external shocks") is located farther out,
    at about 3 Rvir, with large Mach numbers (≈100), covering about 40%–60% of the
    surface area. We simulate SZ surface brightness maps of relaxed massive galaxy
    clusters drawn from high-resolution AMR runs, and conclude that ALMA should be
    capable of detecting the virial shocks in massive clusters of galaxies. More simulations
    are needed to improve estimates of astrophysical noise and to determine optimal
    observational strategies.@eng
