Detection of companion galaxies around hot dust-obscured hyper-luminous galaxy W0410-0913 [PDF]
Nature Communications, 2022 Lyman-alpha emission is one of the observational probes for the high-redshift universe. Here, the authors show several Lyman-alpha emitting companion galaxies around the hot dust-obscured galaxy W0410-091 suggesting that the galaxy evolves in a very ...

Clustering of Lyman-Alpha Emitters galaxies
New Astronomy Reviews, 2009 Abstract Galaxy clustering properties have been studied for decades to constrain cosmological parameters and have today, with large datasets of high-redshift sources piling up, become a powerful tool to discriminate and characterize primeval galaxies.

NO OVERDENSITY OF LYMAN-ALPHA EMITTING GALAXIES AROUND A QUASAR AT z ∼ 5.7 [PDF]
Astrophysical Journal, 2017 ABSTRACT Bright quasars, observed when the universe was less than one billion years old (z > 5.5), are known to host massive black holes (∼109 M ⊙) and are thought to reside in the center of massive dark matter overdensities.

The Astrophysical Journal, 2023 We present the Texas Euclid Survey for Ly α (TESLA), a spectroscopic survey in the 10 deg ^2 of the Euclid North Ecliptic Pole (NEP) field. Using TESLA, we study how the physical properties of Ly α emitters (LAEs) correlate with Ly α emission to ...

The Astrophysical Journal Letters, 2023 Ly α emission is possibly the best indirect diagnostic of Lyman continuum (LyC) escape since the conditions that favor the escape of Ly α photons are often the same that allow for the escape of LyC photons.

The Astrophysical Journal, 2023 The 100% detection rate of Ly α emission in a sample of four luminous z ∼ 8 galaxies with red Spitzer/IRAC colors suggests objects with unusual ionizing capabilities that created early ionized bubbles in a neutral era.

The Lyman Alpha Reference Sample
Astronomy & Astrophysics, 2022 Aims.We useHubbleSpace Telescope data of 45 nearby star-forming galaxies to investigate properties of Lyman-alpha (Lyα) halos, Lyαmorphology, and the star-forming characteristics of galaxies. We study how the morphology of Lyαemission is related to other Lyαobservables.

The Astrophysical Journal, 2023 Although low-mass star-forming galaxies are the leading candidates of the reionization process, we cannot conclusively rule out high-mass star-forming galaxies as candidates.
