"We were not expecting it to be all that successful. I'm amazed at how powerful this is. We know the simulations have limitations, so we don't want to make too strong a claim. But we don't think this is just a lucky fluke."
"The VELA simulations have had a lot of success in terms of helping us understand the CANDELS observations. Nobody has perfect simulations, though. As we continue this work, we will keep developing better simulations."
