Synergies Between Galaxy Surveys and Reionization Measurements [PDF]

, 2019
The epoch of reionization is one of the most exciting frontiers in astrophysics. Here we describe how the combination of galaxy surveys and direct 21-cm measurements of reionization can illuminate numerous mysteries of this fascinating era.

Separating the memory of reionization from cosmology in the Ly$\alpha$ forest power spectrum at the post-reionization era

, 2023
It has been recently shown that the astrophysics of reionization can be extracted from the Ly$\alpha$ forest power spectrum by marginalizing the memory of reionization over cosmological information.

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.

Sensitivity of the redshifted 21 cm signal from the Dark Ages to parameters of primordial magnetic fields

Astronomy & Astrophysics
We analyse the impact of the decaying magnetic turbulence of primordial magnetic fields (PMFs) and ambipolar diffusion on the ionisation and thermal history of the Dark Ages Universe (30 ≤ z ≤ 300), and its imprint on the spectral profile of the global ...

Dark-ages reionization and galaxy formation simulation V: Morphology and statistical signatures of reionization

, 2016
We use the Dark-ages, Reionization And Galaxy formation Observables from Numerical Simulations (DRAGONS) framework to investigate the effect of galaxy formation physics on the morphology and statistics of ionized hydrogen (H II) regions during the Epoch ...

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.

Cosmic microwave background polarization and reionization: Constraining models with a double reionization

, 2005
Neutral hydrogen around high–z QSO and an optical depth $\tau \sim 0.17$ can be reconciled if reionization is more complex than a single transition at $z\simeq 6{-}8$. Tracing its details could shed a new light on the first sources of radiation.

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.
