  bibo_abstract:
  - Using deep, medium-resolution, JWST rest-optical spectra of a sample of typical
    star-forming galaxies (Lyman-break galaxies and Lyman-α emitters) from the LyC22
    survey at z ∼ 3, we determined the nebular abundances of N, O, and Ne relative
    to H for a subsample of 25 objects with a direct method based on auroral [O III]
    λ4363 line detections. Our measurements increased the number of accurate N/O determinations
    at z ∼ 2 − 4 using a homogeneous approach. We found a mean value of log(N/O) =
    −+0.25−0.21 over a metallicity range of 12 + log(O/H) = 7.56 to 8.44. The observed
    N/O ratio and scatter are indistinguishable from that observed in low-z galaxies
    and H II regions over the same metallicity range, thus showing no redshift evolution
    of N/O for typical galaxies over a significant fraction of cosmic time. We also
    show that typical z ∼ 3 galaxies have a similar offset in the BPT diagram to galaxies
    from the low-z Lyman Continuum Survey (LzLCS) when compared to the average of
    SDSS galaxies, and we demonstrate that this offset is not due to enhanced nitrogen
    abundances. Our results establish a basis for future studies of the evolution
    of N and O at higher redshifts.@eng
