  bibo_abstract:
  - While bursty star formation in low-mass galaxies has been observed in local populations
    and reproduced in simulations, the dormant phase of the burst cycle has not been
    well studied beyond the local Universe due to observational limitations. We present
    a unique sample of 43 JWST PRISM spectra of low-mass galaxies (M⋆ < 10^9.5 M⊙)
    at cosmic noon (1 < z < 3), uniformly selected on F200W magnitude and precise
    photometric redshifts enabled by 20-band JWST photometry from the UNCOVER and
    MegaScience surveys. The spectra reveal numerous strong Balmer breaks, which are
    negatively correlated with the galaxies’ Hα equivalent width. By comparing these
    observations to synthetic samples of spectra generated using a simple parameterization
    of bursty star formation histories, we show that star formation in low-mass galaxies
    at cosmic noon is likely dominated by burst cycles with long timescales (≳100
    Myr) and large deviations below the star-forming main sequence (≳0.8 dex). Our
    results suggest that galaxies in this population—at least those within our detection
    limits—should not be classified solely by their current star formation rates,
    but instead viewed as a unified population undergoing dynamic movement above and
    below the star-forming main sequence. The derived constraints demonstrate that
    long-timescale fluctuations are important for this class of galaxies, indicating
    that galaxy-scale gas cycles—rather than molecular-cloud-scale stochasticity—are
    the primary regulators of star formation variability in low-mass galaxies at cosmic
    noon.@eng
