Erm...and the energy source for this accelerator is precisely what?
The stars themselves?

I'll admit I have no clue how to precisely estimate the mass of a galaxy.
However, one can extrapolate given:

[1] the mass of the Earth (Cavendish results)
[2] the orbit period of the Earth around the Sun (it's 1 year and
has been known since antiquity)
[3] the distance between Sun and Earth (various methods)

We now can estimate the mass of the Sun. Looking for similar stars
in the Galaxy as pairs of spectroscopic binaries may allow for
the estimation of mass of other stars with which these "other Suns"
are paired with; armed with that information one can then tote up
all of the visible stars in the Galaxy and hope that there's a
similar mix in the invisible ones. We can also look at other Galaxies
to get a rough idea of how ours is shaped.

So now we can estimate the mass of the stars in a Galaxy.

At this point I for one am stuck for lack of actual data but astronomers
routinely play "sky survey".
