While the Lyman α (Ly α) emission line serves as an important tool in the study of galaxies at z ≲ 6, finding Ly α emitters (LAE) at significantly higher redshifts has been more challenging, probably because of the increasing neutrality of the intergalactic medium above z ∼ 6. Galaxies with extremely high rest-frame Ly α equivalent widths, EW(Ly α) ≳ 150 Å, at z > 6, are good candidates for Ly α follow-up observations, and can stand out in multiband imaging surveys because of their unusual...[Show more]
