Does CMB Distortion Disfavour Intermediate Mass Dark Matter?
  We investigate the published constraints on MACHOs in the mass region $10^2 -
10^5 M_{\odot}$ and their possible contribution to dark matter. We focus on
constraints which rely on the accretion of matter which emits X-rays that can
lead, after downgrading to microwaves, to distortion of the CMB spectrum and
isotropy. The most questionable step in this chain of arguments is the use of
overly simplified accretion models. We compare how the same accretion models
apply to X-ray observations from supermassive black holes SMBHs, M87 and Sgr
A*. The comparison of these two SMBHs with intermediate mass MACHOs suggests
that the latter could, after all, provide the constituents of all the dark
matter. We discuss the status of other constraints on IM-MACHOs.
