Fast large-scale reionization simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We present an efficient method to generate large simulations of the Epoch of Reionization (EoR) without the need for a full 3-dimensional radiative transfer code. Large dark-matter-only simulations are post-processed to produce maps of the redshifted 21cm emission from neutral hydrogen.

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‐

Astronomy & Astrophysics, 2004 The possibility that population III stars have reionized the Universe at redshifts greater than 6 has recently gained mo- mentum with WMAP polarization results. Here we analyse the role of early dust produced by these stars and ejected into the in- tergalactic medium.

Update and ADMET Profile of the Latin American Natural Product Database: LANaPDB
Molecular Informatics, Volume 44, Issue 11-12, November‐December 2025.LANaPDB was updated with 1,164 nonduplicate new compounds coming from Argentina and Panama. Moreover, 41 ADMET (absorption, distribution, metabolism, excretion, and toxicity)‐related parameters were determined, and the results were compared with the Universal Natural Products Database and the approved small‐molecule drugs.

An Estimate of the Impact of Reionization on Supermassive Black Hole Growth
The Astrophysical JournalThe 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 ...

Astronomy & AstrophysicsContext. The Lyman-α forest of high-redshift quasars is a powerful probe of the late stages of the epoch of reionization (EoR), in particular thanks to the presence of Gunn-Peterson troughs.

Cutoff and Emergence of Dart Leaders in an Unbranched Positive Leader Simulation
Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract Channel cutoff is the process by which an active lightning channel cools down, goes dark, and loses its ability to effectively conduct electricity. Current cutoff precedes several lightning phenomena, notably dart leaders and return strokes, but the process by which a hot, highly‐conducting leader channel can undergo current cutoff is poorly ...

Astronomy & AstrophysicsContext. Measurements of the cosmic 21 cm background need to achieve a high dynamic range to isolate it from bright foreground emissions. Instrumental calibration inaccuracies can compromise the spectral fidelity of the smooth foreground continuum ...

The Universe is at Most 88% Neutral at z = 10.6
The Astrophysical Journal Letters, 2023 Recent observations of GN-z11 with JWST have revealed a Ly α emission line with an equivalent width (EW) of 18 ± 2 Å. At z = 10.6, this galaxy is expected to lie in the heart of reionization.
