hi there, I was just at a seminar in which the speaker was talking about using gravitational lensing to investigate galaxy clusters
my question is pretty simple: is there any effect on the redshift of the image of an object which is "lensed" by the gravitational lensing phenomenon? I would imagine that it would not, because all that's going on is bending of the path that the light is taking. However, I am not very well educated on the topic, and perhaps there are things that I am not taking into account.
