The Impact of Patchy Reionization on Ultrafaint Dwarf Galaxies [PDF]
The Astrophysical Journal, 2023 We investigate how patchy reionization affects the star formation history (SFH) and stellar metallicity of ultrafaint dwarf galaxies (UFDs). Patchy reionization refers to varying ultraviolet background strengths depending on a galaxy’s environment ...

Cosmic Reionization on Computers: Properties of the Post-reionization IGM [PDF]
The Astrophysical Journal, 2017 Abstract We present a comparison between several observational tests of the post-reionization intergalactic medium and the numerical simulations of reionization completed under the Cosmic Reionization On Computers (CROC) project. The CROC simulations match the gap distribution reasonably well, and also provide a good match for the ...

Reaction Environment Engineering for Selective C3+ Formation in CO2 Electroreduction: Progress and Perspectives [PDF]
Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.This work focuses on how to improve the selectivity and activity of electrocatalytic CO2 reduction to C3+ products, by the integration of electrocatalyst and electrolyte co‐design. We summarize key C3+ formation mechanisms and provide a comprehensive reaction network through thermodynamic analysis.

A SPectroscopic Survey of Biased Halos In the Reionization Era (ASPIRE): JWST Supports Earlier Reionization around [O iii] Emitters [PDF]
The Astrophysical JournalUnderstanding when and how reionization happened is crucial for studying the early structure formation and the properties of the first galaxies in the Universe. At z > 5.5, the observed intergalactic medium (IGM) optical depth shows a significant scatter,

The epoch of reionization [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 We have modelled the process of reionization of the IGM by photoionization by galaxies, in order to predict the epoch of reionization. We use a sophisticated semi-analytic model to track the formation of galaxies. Our study represents a much more complete and physically consistent modelling of reionization than has been conducted in the past ...

The reionization of carbon [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Observations suggest that CII was more abundant than CIV in the intergalactic medium towards the end of the hydrogen reionization epoch. This transition provides a unique opportunity to study the enrichment history of intergalactic gas and the growth of the ionizing background (UVB) at early times.

Living Reviews in Computational Astrophysics, 2022 AbstractThe transformation of cold neutral intergalactic hydrogen into a highly ionized warm plasma marks the end of the cosmic dark ages and the beginning of the age of galaxies. The details of this process reflect the nature of the early sources of radiation and heat, the statistical characteristics of the large-scale structure of the Universe, the ...

Simulating Reionization: Character and Observability. [PDF]
, 2008 In recent years there has been considerable progress in our understanding of the nature and properties of the reionization process. In particular, the numerical simulations of this epoch have made a qualitative leap forward, reaching sufficiently large ...
