Fragmentation and the formation of primordial protostars: the possible role of Collision Induced Emission
Emanuele Ripamonti, Tom Abel
The mechanisms which could lead to chemo-thermal instabilities and fragmentation during the formation of primordial protostars are investigated analytically. We introduce approxima…
Radiation Hydrodynamical Evolution of Primordial H II Regions
Daniel Whalen, Tom Abel, Michael L. Norman
We simulate the ionization environment of z ~ 20 luminous objects formed within the framework of the current CDM cosmology and compute their UV escape fraction. These objects are l…
The Angular Momentum of Gas in Proto-Galaxies: II -- The Impact of Preheating
Frank C. van den Bosch, Tom Abel, Lars Hernquist
We examine the effect of preheating of the intergalactic medium on galaxy formation using cosmological hydrodynamical simulations. By performing simulations both with and without a…
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…
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…
Simulations of Early Structure Formation: Primordial Gas Clouds
Naoki Yoshida, Tom Abel, Lars Hernquist +1
(abridged) We use large cosmological simulations to study the origin of primordial star-forming clouds in a Lambda CDM universe, by following the formation of dark matter halos and…
