High-resolution Observations of CO(3–2) in Haro 2: Cool Molecular Outflows of a Lyα Emitter

open access: yesThe Astronomical Journal
Haro 2 is a blue compact dwarf galaxy and the closest (at 21 Mpc) known Lyα emitter. UV and optical observations have found Haro 2 to be immersed in shells of partly ionized gas expanding at ∼200 km s ^−1 .

On the origins of oxygen: ALMA and JWST characterise the multi-phase, metal-enriched, star-bursting medium within a 'normal' $z > 11$ galaxy

open access: yesThe Open Journal of Astrophysics
The unexpectedly high abundance of galaxies at $z > 11$ revealed by JWST has sparked a debate on the nature of early galaxies and the physical mechanisms regulating their formation.

An Extremely Metal-poor Lyα Emitter Candidate at z = 6 Revealed through Absorption Spectroscopy

open access: yesThe Astrophysical Journal Letters
We report the discovery of a Ly α emitter (LAE) candidate in the immediate foreground of the quasar PSO J158-14 at z _QSO = 6.0685 at a projected distance ∼29 pkpc that is associated with an extremely metal-poor absorption system.

The THESAN project: Lyman-alpha emitters as probes of ionized bubble sizes

open access: yesThe Open Journal of Astrophysics
We use the THESAN radiation-hydrodynamics simulations to investigate how Lyman-$\alpha$ emitters (LAEs) trace ionized bubble sizes during the Epoch of Reionization.

Bayesian Component Separation for DESI LAE Automated Spectroscopic Redshifts and Photometric Targeting

open access: yesThe Astrophysical Journal
Lyα emitters (LAEs) are valuable high-redshift cosmological probes traditionally identified using specialized narrowband photometric surveys. In ground-based spectroscopy, it can be difficult to distinguish the sharp LAE peak from residual sky emission ...
