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.

Generative models of 21 cm Epoch of Reionisation lightcones with 3D scattering transforms

Astronomy & Astrophysics
The 21 cm signal from the Epoch of Reionisation (EoR) is observed as a 3D dataset known as a lightcone, consisting of two spatial sky plane axes and a redshift (frequency) axis.

Constraints on X-ray Emissions from the Reionization Era

, 2012
We examine the constraints on soft X-ray emissions from the reionization era. It has generally been assumed that the Universe was reionized by ultraviolet photons from massive stars.

A GLIMPSE into the very faint end of the Hβ+[O III]λλ4960,5008 luminosity function at z ∼ 7 – 9 behind Abell S1063

Astronomy & Astrophysics
We used the ultra-deep GLIMPSE JWST/NIRCam survey to constrain the faint end of the [O III]+Hβ luminosity function (LF) down to 1039erg s−1 at z ∼ 7 − 9 behind the lensed Hubble Frontier Field galaxy cluster Abell S1063.

Reionization on ice

, 2006
The case for substantial far infrared ice emission in local ultraluminous infrared galaxies, expected based on the presence of mid-infrared ice absorption in their spectra and the known far infrared optical properties of ice, is still largely unsupported by direct observation owing to insufficient far infrared spectral coverage.

The SPHINX public data release

Astronomy & Astrophysics
Context. Low-ionisation state (LIS) metal absorption lines, such as Si II λ1526, are widely used to trace the properties and dynamics of the interstellar medium (ISM) in galaxies.

POLAR

Astronomy & Astrophysics
Context. Galaxies may suffer some starburst and quenched periods in their history due to galaxy mergers and feedback. However, semi-numerical simulations of the Epoch of Reionization (EoR) do not accurately model the effects of the star formation history

The Kinetic Sunyaev-Zel'dovich Effect from Radiative Transfer Simulations of Patchy Reionization

, 2006
We present the first calculation of the kinetic Sunyaev-Zel'dovich (kSZ) effect due to the inhomogeneous reionization of the universe based on detailed large-scale radiative transfer simulations of reionization.
