Studying Reionization with Ly-alpha Emitters

, 2007
We show that observations of high-redshift Ly-alpha emitters (LAEs) have the potential to provide definitive evidence for reionization in the near future.

The mean free path of hydrogen ionizing photons during the epoch of reionization [PDF]

, 2017
We use the Aurora radiation-hydrodynamical simulations to study the mean free path (MFP) for hydrogen ionizing photons during the epoch of reionization. We directly measure the MFP by averaging the distance 1 Ry photons travel before reaching an optical ...

What Next-Generation 21 cm Power Spectrum Measurements Can Teach Us About the Epoch of Reionization [PDF]

, 2013
A number of experiments are currently working towards a measurement of the 21 cm signal from the Epoch of Reionization. Whether or not these experiments deliver a detection of cosmological emission, their limited sensitivity will prevent them from ...

Long Dark Gaps in the Lyβ Forest at z < 6: Evidence of Ultra-late Reionization from XQR-30 Spectra

The Astrophysical Journal, 2022
We present a new investigation of the intergalactic medium near reionization using dark gaps in the Ly β forest. With its lower optical depth, Ly β offers a potentially more sensitive probe to any remaining neutral gas compared to the commonly used Ly α ...

Constraining reionization using 21 cm observations in combination with CMB and Lyman-alpha forest data

, 2009
In this paper, we explore the constraints on the reionization history that are provided by current observations of the Lyman-alpha forest and the CMB.

First Observations and Characteristics of Positive Upward Illumination Strokes

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Upward Illumination (UI) strokes are a subtype of cloud‐to‐ground (CG) return strokes characterized by two concurrent branches striking the ground a few milliseconds apart. The luminous channel of an UI stroke does not connect to the main channel, which gives this phenomenon its name.

UV Radiative Feedback During the Advanced Stages of Reionization [PDF]

, 2008
The ionizing ultraviolet background (UVB) during reionization can suppress the gas content of low-mass galaxies, even those capable of efficient atomic cooling, and thus lead to an extended reionization epoch.

A Proteochemometric Model for Ligands of the SLC5 Transporter Family

Archiv der Pharmazie, Volume 359, Issue 1, January 2026.
A novel proteochemometric model was developed to predict the activity and selectivity of SLC5 family inhibitors. The model's performance was validated using 10‐fold cross‐validation on publicly available datasets achieving Q2 = 0.79 and MSE < 0.32. Detailed analysis of the results enabled the identification of a new, previously unrecognized selectivity‐

An Estimate of the Impact of Reionization on Supermassive Black Hole Growth

The Astrophysical Journal
The supermassive black holes (SMBHs) that power active galactic nuclei found at z ≥ 6 were formed during the Epoch of Reionization. Because reionization is an inhomogeneous process, the physical properties of SMBH host-galaxy environments will vary ...

The Impact of Stellar Initial Mass Function on the Epoch of Reionization: Insights from Semi-Analytic Galaxy Modeling

Universe
The adequate choice of stellar initial mass function (IMF) is crucial when studying high-z galaxy formation and the epoch of reionization (EoR) models. We employ the semi-analytical galaxy model L-Galaxies2020 and the dark matter simulation Millennium-II,
