  - 'We investigate the properties of extreme emission line galaxies (EELGs) at z = 4 − 9
    and their role in reionization. Compact, low-mass galaxies with intense optical
    emission lines are linked to elevated specific star formation rates (sSFRs) and
    recent bursts of star formation. Feedback in these systems may enable the leakage
    of ionizing radiation into the intergalactic medium. Using JWST/NIRSpec spectroscopy
    from the CAPERS, CEERS, and RUBIES surveys, we compiled 160 NIRCam-selected EELGs
    in the EGS field. These galaxies show extreme rest-frame equivalent widths (EWs),
    with a median EW([O III]+Hβ) = 1616 Å and EW(Hα) = 763 Å. They are low-mass (median
    log(M★/M⊙) = 8.26) with high sSFRs (median 43 Gyr−1), above the z ∼ 6 main sequence.
    UV slopes are diverse, with a median value of β = −2.0, and only 7% have extremely
    blue continua (β < −2.6). Emission-line diagnostics suggest stellar populations
    as the primary ionizing source, although an AGN fraction of 14% cannot be entirely
    ruled out. These galaxies are efficient ionizing photon producers, with median
    log(ξion [Hz erg−1]) = 25.37, exceeding typical values at similar redshifts. Escape
    fractions, however, are heterogeneous: 16% of EELGs at z < 7 show escape fractions
    > 5% for both Lyα and LyC photons, while 82% lack detectable Lyα emission. The
    median inferred LyC escape fraction is modest (5%) but enhanced in compact super-Eddington
    systems with sSFR > 25 Gyr−1. These results indicate that EELGs contribute approximately
    16 − 40% of the total ionizing emissivity required to sustain hydrogen reionization.
    EELGs are extremely compact, with a median effective radius of 0.49 kpc, and exhibit
    a recent star formation burst. Our analysis indicates that sSFR and star formation
    rate surface density are the primary drivers of their extreme emission line strengths.@eng'
