Are Galaxies Moving Faster Than Light Due to Space Expansion?

[Yukterez]

But the now-velocity of the galaxy and the emission-velocity was mixed up. I.e., it should read 3.62c at emission, and 2.08c now - not the other way around.

Did I mix that up? If so, I of course meant it the other way around (:
Edit: I see, I was obviously too stupid to read my own chart (:

hence the 5 km/s value is not known unless a absolute frame of reference is defined. isn't this correct

No. It isn't correct. The 5km/s value is simply relative to some arbitrary reference frame.

Ah, got it.

On the x-axis you have the redshift (as observed today), and on the y-axis the recessional velocity (orange is the velocity at emission and brown at absorption)

You see that objects with z < 1.8963 are faster today than they were when they emitted the light we receive now (the relative distance since then has changed more than the scale factor), while objects with z > 1.8963 are slower now than they were when they emitted their light (the expansion rate fell more than the distance increased while the light travelled).
