PRISMS: U37126, a very blue ISM-naked starburst at z = 10.255 with a nearly 100% Lyman continuum escape fraction

Astronomy & Astrophysics
We present very deep (≈11 hours on-source) JWST/MIRI low-resolution spectroscopy of the rest-frame optical emission of U37126, a UV-bright (MUV ≃ −20) mildly lensed (μ ≃ 2.2) galaxy at z = 10.255.

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

Reionization of the inhomogeneous universe

, 1999
A model of the density distribution in the intergalactic medium, motivated by that found in numerical simulations, is used to demonstrate the effect of a clumpy IGM and discrete sources on the reionization of the universe.

High-redshift Quasars as Probes of Cosmic Reionization

Cosmic reionization was the last major phase transition of atomic hydrogen in the IGM, empowered by the first luminous sources in the universe. With extensive studies over the past two decades, the timeline of the second half of reionization has been ...

Discriminating Planck reionisation histories with the kSZ effect

Astronomy & Astrophysics
The epoch of reionisation is a key phase in cosmic history, but its detailed evolution remains poorly constrained by current cosmic microwave background (CMB) observations.

Neutral beam system reionization losses [PDF]

, 1978
A slow, linear pressure rise in the drift ducts of the PLT neutral beam systems, and the resulting reionization losses of neutral beam power, are reported and examined.

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.

Joining Bits and Pieces of Reionization History [PDF]

, 2019
International audienceCosmic microwave background (CMB) temperature and polarization anisotropies from Planck have estimated a lower value of the optical depth to reionization (τ) compared to WMAP.
