emitters (LAEs) at z≃ 2.2 for which high-resolution FUV spectra from Magellan/MagE are
available. We detect nebular emission lines including Hα on the individual basis and low-
ionization interstellar (LIS) absorption lines in a stacked FUV spectrum, and measure
average offset velocities of the Lyα line, Δv Lyα, and LIS absorption lines, Δv abs, with
respect to the systemic velocity defined by the nebular lines. For a sample of eight z∼ 2–3 …
