We present predictions for two statistical measures of the hydrogen reionization process at high redshift. The first statistic is the number of neutral segments identified in spectra of high-redshift QSOs as a function of their length. The second is the cross-correlation of neutral regions with possible sources of ionizing radiation. These independent probes are sensitive to the topology of the ionized regions. If reionization proceeded from high- to low-density regions, then the cross…

The morphology of cosmological reionization by means of Minkowski functionals
The morphology of the total gas and the neutral hydrogen (H I) distributions during the cosmological epoch of reionization can be quantified with Minkowski functionals (MFs) of isodensity surfaces.
The spin temperature of neutral hydrogen during cosmic pre-reionization
We re-examine the role of collisions in decoupling the H i 21-cm spin temperature from the cosmic microwave background (CMB). The cross-section for de-exciting the 21-cm transition in collisions with
Probing non-Gaussian features in the H i distribution at the epoch of re-ionization
The H i distribution at the epoch of re-ionization (EOR) is largely determined by the sizes and distribution of the ionized regions. In the scenario where the ionized regions have comoving sizes of
Constraining the reionization history with qso absorption spectra
We use a semi-analytical approach to simulate absorption spectra of QSOs at high redshifts with the aim of constraining the cosmic reionization history. We consider two physically motivated and
Quasar Proximity Zones and Patchy Reionization
Lyα forest absorption spectra toward quasars at z ~ 6 show regions of enhanced transmission close to their source. Several authors have argued that the apparently small sizes of these regions
The Alcock-Paczyński test in redshifted 21-cm maps
We examine the possibility of constraining the cosmological mean mass and dark energy densities by an application of the Alcock-Paczynski test on redshifted 21-cm maps of the epoch of reionization.
Astrophysics in 2003
Five coherent sections appear this year, addressing solar physics, cosmology (with WMAP highlights), gamma-ray bursters (and their association with Type Ia supernovae), extra-solar-system planets,


Non-uniform reionization by galaxies and its effect on the cosmic microwave background
We present predictions for the reionization of the intergalactic medium (IGM) by stars in high-redshift galaxies, based on a semi-analytic model of galaxy formation. We calculate ionizing
Polarization of the cosmic microwave background from nonuniform reionization.
We study the polarization anisotropy in the cosmic microwave background (CMB) resulting from patchy reionization of the intergalactic medium by stars in galaxies. It is well known that the
Signatures of Stellar Reionization of the Universe
The high ionization level and nonzero metallicity (~1% Z☉) of the intergalactic gas at redshifts z 5 implies that nonlinear structure had started to form in the universe at earlier times than we
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
Cosmological Reionization by Stellar Sources
I use cosmological simulations that incorporate a physically motivated approximation to three- dimensional radiative transfer that recovers correct asymptotic ionization front propagation speeds for
Inhomogeneous reionization of the intergalactic medium regulated by radiative and stellar feedbacks
We study the inhomogeneous reionization in a critical density CDM universe resulting from stellar sources, including Population III objects. The spatial distribution of the sources is obtained from
Cosmic microwave background anisotropies resulting from feedback-regulated inhomogeneous reionization
We calculate the secondary anisotropies in the cosmic microwave background (CMB) produced by inhomogeneous reionization from simulations in which the effects of radiative and stellar feedback effects
On the Threshold of the Reionization Epoch
Discovery of the cosmic reionization epoch would represent a significant milestone in cosmology. We present Keck spectroscopy of the quasar SDSS 1044-0125, at z = 5.73. The spectrum shows a dramatic
