Weighing gas-rich starless halos: Dark matter parameter inference based on gas distributions

Astronomy & Astrophysics
Context. Reionization-limited H I clouds (RELHICs) are starless dark matter halos that retain a significant neutral hydrogen (H I) reservoir. The gas resides in near hydrostatic equilibrium within the dark matter potential and in thermal equilibrium with

Studying dark gaps in Lyman-α forest transmission with large reionization simulations

Astronomy & Astrophysics
The physical conditions of the intergalactic medium (IGM) during the final stages of cosmic reionization (z ∼ 5.0 − 6.0) are not yet fully understood.

Reionization in hestia : studying reionization in the LG through zoom simulations

Monthly Notices of the Royal Astronomical Society
ABSTRACT While cosmic reionization has been broadly constrained by global observables, the interplay between internal sources [Milky Way (MW), M31, and their satellites] and external ionization fronts remains poorly understood in a realistic Local Group (LG) context. To address this issue, we perform radiative transfer post-processing

Cosmic Reionization on Computers: The Evolution of the Ionizing Background and Mean Free Path

The Astrophysical Journal
Observations of the end stages of reionization indicate that at z  ≈ 5–6, the ionizing background is not uniform and the mean free path (MFP) changes drastically.

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,

LIMFAST. III. Timing Cosmic Reionization with the 21 cm and Near-infrared Backgrounds

The Astrophysical Journal
The timeline of cosmic reionization remains uncertain despite sustained efforts to study how the ionizing output of early galaxies shaped the intergalactic medium (IGM).
