Recently, there has been a great deal of interest in understanding the reionization of hydrogen in the intergalactic medium (IGM). One of the major outstanding questions is how this event proceeds on large scales. Motivated by numerical simulations, we develop a model for the growth of H II regions during the reionization era. We associate ionized regions with large-scale density fluctuations and use the excursion set formalism to model the resulting size distribution. We then consider ways in… 

Characteristic scales during reionization

One of the key observables of the reionization era is the distribution of neutral and ionized gas. Recently, Furlanetto, Zaldarriaga and Hernquist developed a simple analytic model to describe the

The morphology of H ii regions during reionization

It is possible that the properties of H II regions during reionization depend sensitively on many poorly constrained quantities [the nature of the ionizing sources, the clumpiness of the gas in the


Early in the reionization process, the intergalactic medium (IGM) would have been quite inhomogeneous on small scales, due to the low Jeans mass in the neutral IGM and the hierarchical growth of

Simulating Cosmic Reionization at Large Scales I: the Geometry of Reionization

We present the first large-scale radiative transfer simulat ions of cosmic reionization, in a simulation volume of (100 h 1 Mpc) 3 . This is more than a 2 orders of magnitude improvement over

An improved model of H ii bubbles during the epoch of reionization

The size distribution of ionized regions during the epoch of reionization -- a key ingredient in understanding the HI power spectrum observable by 21cm experiments -- can be modelled analytically


In this paper, we investigate the nature and distribution of large neutral regions during the late epoch of reionization. In the “bubble model” of reionization, the mass distribution of large ionized

The effect of peculiar velocities on the epoch of reionization 21-cm signal

We have used seminumerical simulations of reionization to study the behaviour of the power spectrum of the epoch of reionization 21-cm signal in redshift space. We have considered two models of

Distinguishing reionization models using the largest cluster statistics of the 21-cm maps

. The evolution of topology and morphology of ionized or neutral hydrogen during different stages of the Epoch of Reionization (EoR) have the potential to provide us a great amount of information

Quasar H II Regions During Cosmic Reionization

Cosmic reionization progresses as HII regions form around sources of ionizing radiation. Their average size grows continuously until they percolate and complete reionization. We demonstrate how this

The Intergalactic Medium at High Redshifts

The intergalactic medium (IGM) contains >95% of the mass in the Universe at high redshifts, and its properties control the earliest phases of structure formation and the reionization process.



Reionization of the Inhomogeneous Universe

A model of the density distribution in the intergalactic medium (IGM), motivated by that found in numerical simulations, is used to demonstrate the effect of a clumpy IGM and discrete sources on the

Statistical Probes of Reionization with 21 Centimeter Tomography

We consider the degree to which 21 cm tomography of the high-redshift universe can distinguish different ionization histories. Using a new analytic model for the size distribution of H II regions

Probing the Reionization History Using the Spectra of High-Redshift Sources

We quantify and discuss the footprints of neutral hydrogen in the intergalactic medium (IGM) on the spectra of high-redshift (z ~ 6) sources, using mock spectra generated from hydrodynamical

Fossil H ii regions: self-limiting star formation at high redshift

Recent results from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite suggest that the intergalactic medium (IGM) was significantly reionized at redshifts as high as z ∼ 17. At this early

21 Centimeter Fluctuations from Cosmic Gas at High Redshifts

The relatively large Thomson optical depth, τes, inferred recently from the WMAP observations suggests that the universe was reionized in a more complex manner than previously believed. However, the
