Bremsstrahlung vs Gravity swing-by

Question

It seems too me there’s an analogy between the two, but I understand we have a loss of kinetic energy in the former and we can have a gain in the latter. What am I missing?

Answer 1

I’m no expert, but to me the difference seems to be that Bremstrahlung is only one part of a gravity swing-by.
A complete swing-by would consist of Bremsstrahlung, as well as Beschleunigungsstrahlung.
