Deep narrow-band surveys have revealed a large population of faint Ly α emitters (LAEs) in the distant Universe, but relatively little is known about the most luminous sources ( LLyα≳1042.7  erg s−1; LLyα≳L∗Lyα ). Here we present the spectroscopic fo... Read More about The nature of luminous Ly α emitters at z ∼ 2–3: maximal dust-poor starbursts and highly ionizing AGN.

Monthly Notices of the Royal Astronomical Society, 475(3), 3730-3745. https://doi.org/10.1093/mnras/stx3345

The deep, near-infrared narrow-band survey HiZELS has yielded robust samples of H α-emitting star-forming galaxies within narrow redshift slices at z = 0.8,  1.47 and 2.23. In this paper, we distinguish the stellar mass and star-formation rate (SFR)...
