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.

Probing reionization with Lyman-alpha emission lines

, 2003
Lyman-alpha emission from high-redshift galaxies may be a powerful probe of the ionization history of the IGM at z>6: the observed Lyman-alpha emission line is sensitive to the neutral fraction of IGM hydrogen in the range 0.1-1.

The Impact of Cosmic Variance on Inferences of Global Neutral Fraction Derived from Lyα Luminosity Functions during Reionization

The Astrophysical Journal, 2023
We investigate the impact of field-to-field variation, deriving from cosmic variance, in measured Ly α emitter (LAE) luminosity functions (LFs) and this variation’s impact on inferences of the neutral fraction of the intergalactic medium (IGM) during ...

Discovery of a very Lyman-$\alpha$-luminous quasar at z=6.62

, 2017
Distant luminous quasars provide important information on the growth of the first supermassive black holes, their host galaxies and the epoch of reionization.

Line Emitting Galaxies Beyond a Redshift of 7: An Improved Method for Estimating the Evolving Neutrality of the Intergalactic Medium [PDF]

, 2014
The redshift-dependent fraction of color-selected galaxies revealing Lyman alpha emission has become the most valuable constraint on the evolving neutrality of the early intergalactic medium.

Detecting the Earliest Galaxies Through Two New Sources of 21cm Fluctuations

, 2004
The first galaxies that formed at a redshift ~20-30 emitted continuum photons with energies between the Lyman-alpha and Lyman limit wavelengths of hydrogen, to which the neutral universe was transparent except at the Lyman-series resonances.

The JWST/PASSAGE Survey: Testing Reionization Histories with JWST’s First Unbiased Survey for Lyα Emitters at Redshifts 7.5–9.5

The Astrophysical Journal
Ly α emission is one of a few observable features of galaxies that can trace the neutral hydrogen content in the Universe during the Epoch of Reionization (EoR). To accomplish this, we need an efficient way to survey for Ly α emitters (LAEs) at redshifts

Stellar abundances and molecular hydrogen in high-redshift galaxies -the far-ultraviolet view

, 2006
FUSE spectra of star-forming regions in nearby galaxies are compared to composite spectra of Lyman-break galaxies (LBGs), binned by strength of Lyman alpha emission and by mid-UV luminosity.
