What structure might form in a spiral galaxy as a result of a minor merger?

Answer

A central bar structure or slight warping of the outer disk edges

A minor merger, where a small satellite galaxy falls into a much larger spiral, can have varied effects, including funneling new gas into the center to trigger star formation, slightly warping the disk's outer edges, or contributing to the formation of a central bar structure.
