emotional to see <this>

Does "this" refer to "Reichart's work with baboons"? Or refer to "their enthusiasm"?


Other xenotransplantation researchers agree, but this has not dampened their enthusiasm for Reichart’s work with baboons. “It’s not only emotional to see this but also very hard to imagine,” Mohiuddin says. “We just had this baboon, and it has a pig heart—and it’s living. This is not science fiction, this is really for real now.”

    To verify this, we would need to see more text before the passage you've quoted. Nevertheless, I can say with almost 100% certainty your highlighted "this" refers to the research results.
