  bibo_abstract:
  - Finding the first generation of (Population III or Pop III) stars is one of the
    most ambitious and exciting challenges of astrophysics. JWST opened concrete prospects
    for their detection during the Epoch of Reionization, where increasing evidence
    suggests that residual Pop III formation may persist, even within pristine pockets
    of high-mass halos, due to inhomogeneous enrichment. However, the identification
    of Pop III stars within globally enriched environments will be challenging. We
    investigate the detectability of a subdominant Pop III component in/around massive
    (M⋆ ≳ 10^9 M⊙) galaxies at z ≈ 6.5–9 from the dustyGadget cosmological simulation
    suite, and the confusion arising from second-generation (Pop II) stars in their
    surroundings. We find that young (≲1 Myr), massive (MIII ∼ 6 × 10^5 M⊙) Pop III
    clusters forming within these galaxy environments are responsible for strong HeII1640
    line emission (LHeII1640 ≳ 10^41 erg ^s−1), which would be detectable with ≈10(50)
    hr of medium-resolution observations with NIRSpec/IFU at z ≈ 6(10). These bright
    luminosities cannot be produced by standard Pop II populations alone. On the other
    hand, the dominant Pop II component within massive “hybrid” Pop III hosts powers
    strong metal line emission (L[OIII]5007 ≳ 10^42 erg s^−1), indicating that the
    detection of metal lines alone cannot exclude the presence of Pop IIIs in high-z
    galaxy environments. We further discuss candidate selection strategies based on
    Lyα, Hα, and Hβ emission, and how spatially resolved observations may enable the
    detection of isolated, pristine pockets in the outskirts of massive halos.@eng
