  - "We present a study of a pseudo little red dot with no metal lines (Pseudo-LRD-NOM),
    a highly magnified lowmass galaxy behind the lensing cluster A370 at z = 5.96.
    We classify this object as a pseudo-LRD because its red\r\nrest-frame optical
    color is contaminated by a prominent Hα line (with EW0 ≳ 800 Å) present in its
    JWST\r\nNIRSpec spectrum. Hα is dominated by a narrow component and also has a
    minor broad component indicative of\r\nan active black hole with MBH ≈ 5.6 × 10^6
    M⊙. A narrow Hβ emission line is also detected (where the signal-tonoise ratio,
    S/N, is 8), producing a Balmer decrement (narrow) Hα/Hβ = 11. The rest-frame UV
    spectral slope is ßspec/uv = - 1.20 ± 0.28. All these features can be ascribed
    to high dust attenuation. However, no [O III]λ5007 or\r\nany other metal lines
    are detected in the spectrum, so [O III]5007/Hβ < 0.25, at odds with a simple
    dust attenuation explanation. Accounting for all the spectral properties requires
    the model of a starburst with moderate\r\ncolor excess E(B − V )≈0.2–0.5, high
    gas density (nH ≳ 10^6 cm^−3\r\n), and low- to extremely-low gas/stellar\r\nmetallicities
    (Z = 0.01–0.1 Z⊙). The demagnified stellar mass is\r\n× 2.25+\r\n0\r\n1\r\n.\r\n.\r\n8\r\n3\r\n3\r\n0
    10^7 M , and the stellar-mass surface\r\ndensity is = +\r\n* 418 M pc 310\r\n725
    2, similar to that of massive/nuclear star clusters. Pseudo-LRD-NOM provides\r\nevidence
    of massive black-hole growth occurring in a high-density, dusty starburst that
    is at the early stages of its\r\nchemical enrichment, and is likely a precursor
    to a real LRD.@eng"
