We present the average metallicity and star formation rate (SFR) of Lyα emitters (LAEs)
measured from our large-area survey with three narrowband (NB) filters covering the Lyα,[O
ii] λ3727, and Hα+[N ii] lines of LAEs at z= 2.2. We select 919 z= 2.2 LAEs from
Subaru/Suprime-Cam NB data in conjunction with Magellan/IMACS spectroscopy. Of these
LAEs, 561 and 105 are observed with KPNO/NEWFIRM near-infrared NB filters whose
central wavelengths are matched to redshifted [O ii] and Hα nebular lines, respectively. By …

We present the average metallicity and star-formation rate of Lya emitters (LAEs) measured
from our large-area survey with three narrow-band (NB) filters covering the Lya,[OII] 3727,
and Ha+ [NII] lines of LAEs at z= 2.2. We select 919 z= 2.2 LAEs from Subaru/Suprime-Cam
NB data in conjunction with Magellan/IMACS spectroscopy. Of these LAEs, 561 and 105 are
