Ionization fronts and their interaction with density fluctuations: implications for reionization
Ilian T. Iliev, Paul R. Shapiro, Evan Scannapieco +4
The propagation of cosmological ionization fronts (I-fronts) during reionization is strongly influenced by small-scale structure. Here we summarize our recent attemps to understand…
The Equilibrium Structure of CDM Halos
Paul R. Shapiro, Ilian T. Iliev, Hugo Martel +2
Dark-matter halos are the scaffolding around which galaxies and clusters are built. They form when the gravitational instability of primordial density fluctuations causes regions w…
Minihalo photoevaporation during cosmic reionization: evaporation times and photon consumption rates
Ilian T. Iliev, Paul R. Shapiro, Alejandro C. Raga
The weak, R-type ionization fronts (I-fronts) which swept across the intergalactic medium (IGM) during the reionization of the universe often found their paths blocked by cosmologi…
Gravitational Lensing by CDM Halos: Singular versus Nonsingular Profiles
Hugo Martel, Paul R. Shapiro
The gravitational lensing properties of cosmological halos depend upon the mass distribution within each halo. The description of halos as nonsingular, truncated isothermal spheres…
Density Profiles of Dark Halos from their Mass Accretion Histories
Marcelo A. Alvarez, Kyungjin Ahn, Paul R. Shapiro
We use the universal mass accretion history recently reported for simulations of halo formation in the cold dark matter model (CDM) to analyze the formation and growth of a single…
Gravitational lensing by the truncated isothermal sphere model for cosmological halos. I. Individual lens properties
Hugo Martel, Paul R. Shapiro
The gravitational lensing properties of cosmological halos depend upon the mass distribution within each halo. The description of halos as nonsingular, truncated isothermal spheres…
