  bibo_abstract:
  - The first generation of stars, known as population III (Pop III), formed from
    primordial gas consisting solely of hydrogen and helium and is believed to have
    emerged only a few hundred million years after the Big Bang. Detecting the chemical
    enrichment of metal-poor circumgalactic gas offers a promising way to trace the
    enrichment signature of Pop III stars. Along the sight line to the quasar SDSS
    J0100+2802, a metal absorber at z = 5.945, showing over-abundant carbon and silicon
    compared with solar, has been reported to be consistent with the enrichment pattern
    of Pop III stars. Here, using data recorded by the James Webb Space Telescope,
    we report the discovery of an unusually metal-poor galaxy overdensity of 17 members
    (mean metallicity ~3% of solar) near this metal absorber, which is ~0.4 dex more
    metal-poor than coeval galaxies in similarly overdense environments. This less
    chemically evolved system may have provided favourable conditions for preserving
    the absorption signatures of Pop III enrichment. We infer a minimum dark matter
    halo mass of log(Mh,min/M⊙) = 10.68+0.93 −1.72, supporting late-time Pop III formation
    at the outskirts of atomic hydrogen cooling haloes. Our findings open a promising
    observational pathway to identifying the chemical imprints of the first stars
    and constrain the conditions for their formation.@eng
