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

Reionization Parameter Inference from 3D Minkowski Functionals of the 21 cm Signals

The Astrophysical Journal
The Minkowski functionals (MFs), a set of topological summary statistics, have emerged as a powerful tool for extracting non-Gaussian 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 ...

Fluctuations in 21-cm emission after reionization

, 2019
The fluctuations in the emission of redshifted 21-cm photons from neutral intergalactic hydrogen will provide an unprecedented probe of the reionization era.

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.

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.

Extremely ultraviolet-bright starbursts at the end of cosmic reionization

Astronomy & Astrophysics
We present a study of 27 very UV-bright (−22.0 ≲ MUV ≲ −24.4) star-forming galaxies at z ∼ 6 identified in the Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) survey.
