  bibo_abstract:
  - 'The physical processes that led to the formation of billion-solar-mass black
    holes within the first 700 million years of cosmic time, a period known as cosmic
    dawn, remain a puzzle1. Several theoretical scenarios have been proposed to seed
    and rapidly grow black holes2,3,4, but direct observations of these mechanisms
    remain elusive. Here we present a source 660 million years after the Big Bang
    that exhibits singular properties: among the largest hydrogen Balmer breaks reported
    at any redshift, broad multi-peaked Hβ emission, and Balmer line absorption in
    several transitions. We model this source as an enshrouded black hole in which
    the Balmer break and absorption features are a result of extremely dense, turbulent
    gas forming a dust-free envelope around a supermassive black hole5,6. This source
    may provide evidence of an early black hole embedded in dense gas—a theoretical
    configuration proposed to rapidly grow black holes by super-Eddington accretion7,8.
    Radiation from the black hole seems to dominate almost all observed light, leaving
    limited room for contribution from its host galaxy. If the source merged with
    its brighter neighbour, it would resemble the recently discovered ‘little red
    dots’ with perplexing spectral energy distributions9,10,11. The redness of the
    black hole is due to gas, not dust12,13, and scattering, not kinematics, gives
    rise to the complex line shapes and luminosities—black hole masses of these sources
    may therefore be overestimated by orders of magnitude.@eng'
