et al have definitively demonstrated that the "diffuse" galactic X-ray
ridge is produced by discrete stellar-mass objects.

The authors speculate that the discrete sources, which have X-ray
luminosities in the 10^29 - 10^30 erg/sec range, may be accreting
white dwarf stars or coronally active stars.

Another possibility was predicted in 1987 [Oldershaw, R.L.,
Astrophysical Journal, 322, 34-36, 1987]. Discrete Scale Relativity
predicted that the galactic dark matter is primarily in the form of
Kerr-Newman black holes with masses of either 0.145 solar masses or
0.58 solar masses.

It was predicted in the ApJ paper that the members of this population
that reside in the galactic disk would emit accretion-generated X-rays
at luminosities of about 10^29 erg/sec to 10^30 erg/sec.

Is there a way to decide whether the discrete galactic X-ray ridge
sources are the more conventional accreting white dwarfs/coronally
active stars, or whether this population is comprised of the more
unconventional population of Kerr-Newman black holes? Happily there is
a definitive test.

Let me rephrase this. Discrete Scale Relativity makes a falsifiable
prediction. So, if these X-ray sources turn out to be normal stars and
not Kerr-Newman black holes, Discrete Scale Relativity is falsified,
right?
