As the object is visible only because it is

objects in the field are either nearer galaxies or
foreground stars in our galaxy.

When an object of some "standard" size, is located in a much smaller Universe, the image travels out into an expanded Universe, the original object appears magnified... but it was expansion that did it, not gravitation, right? Objects don't stretch with the "balloon", but the image does.

How does intensification occur when climbing out of a gravity well (from a more dense Universe, into a less dense Universe)? It would make more sense to me that the object was more massive, and was still getting hotter CMBR light to pump photoactivity, so its intensity would have nothing to do with gravitational lensing.
