The Santa Barbara cluster comparison project: a comparison of cosmological hydrodynamics solutions
C. S. Frenk, S. D. M. White, P. Bode +22
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 cu…
Cosmological Simulations with Scale-Free Initial Conditions II: Radiative Cooling
J. Michael Owen, David H. Weinberg, Jens V. Villumsen
The growth of structure from scale-free initial conditions is one of the most important tests of cosmological simulation methods, providing a realistically complex problem in which…
The Effect of Weak Lensing on the Angular Correlation Function of Faint Galaxies
R. Moessner, B. Jain, J. V. Villumsen
The angular correlation function \wth of faint galaxies is affected both by nonlinear gravitational evolution and by magnification bias due to gravitational lensing. We compute the…
Is lensing of point sources a problem for future CMB experiments?
Max Tegmark, Jens Villumsen
Weak gravitational lensing from large-scale structure enhances and reduces the fluxes from extragalactic point sources with an rms amplitude of order 15%. In cosmic microwave backg…
Clustering of Galaxies in the Hubble Deep Field
Jens V. Villumsen, Wolfram Freudling, Luiz N. da Costa
We compute the two-point angular correlation function for a sample of 1700 galaxies to a magnitude-limit equivalent to using a catalog derived from the…
Baryons, Dark Matter, and the Jeans Mass in Simulations of Cosmological Structure Formation
J. Michael Owen, Jens V. Villumsen
We investigate the properties of hybrid gravitational/hydrodynamical simulations, examining both the numerics and the general physical properties of gravitationally driven, hierarc…
