Reionization: characteristic scales, topology and observability


Iliev, I T; Pen, U L; McDonald, P; Shapiro, P R; Mellema, G; Alvarez, M A (2009). Reionization: characteristic scales, topology and observability. Astrophysics and Space Science, 320(1-3):39-43.

Abstract

Recently the numerical simulations of the process of reionization of the universe at z>6 have made a qualitative leap forward, reaching sufficient sizes and dynamic range to determine the characteristic scales of this process. This allowed making the first realistic predictions for a variety of observational signatures. We discuss recent results from large-scale radiative transfer and structure formation simulations on the observability of high-redshift Ly-α sources. We also briefly discuss the dependence of the characteristic scales and topology of the ionized and neutral patches on the reionization parameters.
