Lyα velocity offset vs. f_esc(Lyα), where a strong anti-correlation between these quantities is observed both in the JADES-only sample (thick dashed line) as well as when looking at the full high redshift Lyα emitter sample (thin dashed line). High f_esc(Lyα) and small velocity offsets likely trace relatively dust and gas-free conditions, which neither leads to considerable resonant scattering of Lyα photons as they travel along a sight line, nor does it attenuate Lyα emission via absorption and scattering.
