Morphology and Evolution in Galaxy Clusters I: Simulated Clusters in the Adiabatic limit and with Radiative Cooling
Nurur Rahman, Sergei F. Shandarin, Patrick M. Motl +2
We have studied morphological evolution in clusters simulated in the adiabatic limit and with radiative cooling. Cluster morphology in the redshift range, , is quantif…

Morphological Measures of nonGaussianity in CMB Maps
Sergei F. Shandarin, Hume A. Feldman, Yongzhong Xu +1
We discuss the tests of nonGaussianity in CMB maps using morphological statistics known as Minkowski functionals. As an example we test degree-scale cosmic microwave background (CM…

Dark Matter, Discreteness and Collision Error in Cosmological N-Body Simulations
Randall J. Splinter, Adrian L. Melott, Sergei F. Shandarin
We report on a series of tests of agreement between three types of N-body simulations: PM, PM, and Tree codes. We find good agreement in both the individual and the statistical…
