Cosmic Reionisation by Stellar Sources: Population III Stars
Aaron Sokasian, Naoki Yoshida, Tom Abel +2
We combine fast radiative transfer calculations with high resolution hydrodynamical simulations to study an epoch of early hydrogen reionisation by primordial stellar sources at re…
Early Structure Formation and Reionization in a Cosmological Model with a Running Primordial Power Spectrum
Naoki Yoshida, Aaron Sokasian, Lars Hernquist +1
(abridged) We study high redshift structure formation and reionization in a LCDM universe under the assumption that the spectral power index of primordial density fluctuations is a…
Cosmic Reionisation by Stellar Sources: Population II Stars
Aaron Sokasian, Tom Abel, Lars Hernquist +1
We study the reionisation of the Universe by stellar sources using a numerical approach that combines fast 3D radiative transfer calculations with high resolution hydrodynamical si…
Early Structure Formation and Reionization in a Warm Dark Matter Cosmology
Naoki Yoshida, Aaron Sokasian, Lars Hernquist +1
We study first structure formation in Lambda-dominated universes using large cosmological N-body/SPH simulations. We consider a standard LCDM model and a LWDM model in which the ma…
The Nature of the Ionising Background at z=2.5-5
Aaron Sokasian, Tom Abel, Lars E. Hernquist
Using radiative transfer calculations and cosmological simulations of structure formation, we study constraints that can be placed on the nature of the cosmic ultraviolet (UV) back…
The Epoch of Helium Reionization
Aaron Sokasian, Tom Abel, Lars. E. Hernquist
We study the reionization of Helium II by quasars using a numerical approach that combines 3D radiative transfer calculations with cosmological hydrodynamical simulations. Sources…
