Cosmological Simulations with Adaptive Smoothed Particles Hydrodynamics
Hugo Martel, Paul R. Shapiro
We summarize the ideas that led to the Adaptive Smoothed Particle Hydrodynamics (ASPH) algorithm, with anisotropic smoothing and shock-tracking. We then identify a serious new prob…
The Central Mass and Phase-Space Densities of Dark Matter Halos: Cosmological Implications
Paul R. Shapiro, Ilian T. Iliev
Current data suggest that the central mass densities and phase-space densities of cosmological halos in the present universe are correlated with their velo…
Cosmological Reionization
Paul R. Shapiro
The universe was reionized by redshift z ~ 6 by a small fraction of the baryons in the universe, which released energy following their condensation out of a cold, dark, and neutral…
The Equilibrium Structure of Cosmological Halos
Ilian T. Iliev, Paul R. Shapiro
We have derived an analytical model for the postcollapse equilibrium structure of cosmological halos as nonsingular truncated isothermal spheres (TIS) and compared this model with…
Explosions and Outflows during Galaxy Formation
Hugo Martel, Paul R. Shapiro
We consider an explosion at the center of a halo which forms at the intersection of filaments inside a cosmological pancake, a convenient test-bed model for galaxy formation. ASPH/…
The Evolution of Dark-Matter Dominated Cosmological Halos
Marcelo Alvarez, Paul R. Shapiro, Hugo Martel
Adaptive SPH and N-body simulations were carried out to study the evolution of the equilibrium structure of dark matter halos that result from the gravitational instability and fra…
