Statistical Properties of X-Ray Clusters: Analytic and Numerical Comparisons
We compare the results of Eulerian hydrodynamic simulations of cluster formation against virial scaling relations between four bulk quantities: the cluster mass, the dark matter velocity dispersion,…

We present results of large-scale three-dimensional simulations of supersonic Euler turbulence with the piecewise parabolic method and multiple grid resolutions up to 20483 points. Our numerical…
The Formation of the First Star in the Universe
It is concluded that at most one massive metal-free star forms per pregalactic halo, consistent with recent abundance measurements of metal-poor galactic halo stars.
Baryons in the Warm-Hot Intergalactic Medium
Approximately 30%-40% of all baryons in the present-day universe reside in a warm-hot intergalactic medium (WHIM), with temperatures in the range 105 < T < 107 K. This is a generic prediction from…
The Santa Barbara Cluster Comparison Project: A Comparison of Cosmological Hydrodynamics Solutions
We have simulated the formation of an X-ray cluster in a cold dark matter universe using 12 different codes. The codes span the range of numerical techniques and implementations currently in use,…

ZEUS-2D : a radiation magnetohydrodynamics code for astrophysical flows in two space dimensions. II : The magnetohydrodynamic algorithms and tests
In this, the second of a series of three papers, we continue a detailed description of ZEUS-2D, a numerical code for the simulation of fluid dynamical flows in astrophysics including a…
Superbubble blowout dynamics
Multiple supernovae and stellar winds from OB associations carve large holes filled with hot gas in the galactic disk. These superbubbles sweep up H I into cold, thin, dense shells and eventually…
