Non-recessional cosmic redshift

In fact, when photons go through galaxies, they come out with
MORE energy than when they went in!!!

I'll let people guess why this is the case. The point is, there's
an effect that's much more significant than dynamical friction,
and works the other way. So: what's this effect?

The dynamo effect?

Maybe that too (...)

I was looking for a pun on "dynamical" and I couldn't do better than
"dynamo". But then I told myself that light is electromagnetic, so my
pun turned into a very wild guess.

.. I'm thinking about the Sachs-Wolf effect,
which people claim to have recently observed.

Interesting, for photons passing through a galaxy
rather than originating in it, my first thought was
the Inverse Compton effect.
