  bibo_abstract:
  - At the epoch of reionization, when the high-redshift inter-galactic medium (IGM)
    is being enriched with metals, the 63.2 micron fine structure line of OI is pumped
    by the ~ 1300 AA soft UV background and introduces a spectral distortion in the
    Cosmic Microwave Background (CMB). Here we use a toy model for the spatial distribution
    of neutral oxygen, assuming metal bubbles surround dark matter halos, and compute
    the fluctuations of this distortion, and the angular power spectrum it imprints
    on the CMB. We discuss the dependence of the power spectrum on the velocity of
    the winds polluting the IGM with metals, the minimum mass of the halos producing
    these winds, and on the cosmic epoch when the OI pumping occurs. We find that,
    although the clustering signal of the CMB distortion is weak \delta y_{rms} ~
    10^{-7} (roughly corresponding to a temperature anisotropy of few nK), it may
    be reachable in deep integrations with high-sensitivity infrared detectors. Even
    without a detection, these instruments should be able to useful constraints on
    the heavy element enrichment history of the IGM.@eng
