A Model For Intergalactic Filaments and Galaxy Formation During the First Gigayear
A. Gayler Harford, Andrew J. S. Hamilton
We propose a physically based, analytic model for intergalactic filaments during the first gigayear of the universe. The structure of a filament is based upon a gravitationally bou…
Intergalactic Filaments as Isothermal Gas Cylinders
A. Gayler Harford, Andrew J. S. Hamilton
Using a cosmological simulation at redshift 5, we find that the baryon-rich cores of intergalactic filaments extending outward from galaxies commonly form isothermal gas cylinders…
Intergalactic baryon-rich regions at high redshift
A. Gayler Harford, Andrew J. S. Hamilton, Nickolay Y. Gnedin
Using a high resolution cosmological simulation of reionization we have examined the differing structures formed by gas and dark matter at a redshift of 5.1. Baryon-rich regions fo…
Star Formation in a Cosmological Simulation of Reionization
A. Gayler Harford, Nickolay Y. Gnedin
We study the luminosity functions of high-redshift galaxies in detailed hydrodynamic simulations of cosmic reionization, which are designed to reproduce the evolution of the Lyman-…
Lyman Break Galaxies and Reionization of the Universe
A. Gayler Harford, Nickolay Y. Gnedin
We present the star formation histories, luminosities, colors, mass to light ratios, and halo masses of "galaxies" formed in a simulation of cosmological reionization. We compare t…
Linear Gas Dynamics in the Expanding Universe: Why the Jeans Scale does not Matter
Nickolay Y. Gnedin, Emily J. Baker, Thomas J. Bethell +9
We investigate the relationship between the dark matter and baryons in the linear regime. This relation is quantified by the so-called ``filtering scale''. We show that a simple ga…
