I've met Saul due to our shared involvement with UC-Berkeley, the Space Sciences Laboratory, Lawrence Berkeley Labs, and the Nearby Supernova Factory collaboration. I don't think I've met Brian. I can't remember whether I've met Adam, but I've operated a telescope for his graduate student, Dan Scolnic.
I figured sooner or later the dark energy guys would get a Nobel, but I really expected it to take a couple more years. Not bad for a bunch of guys in their 40s or early 50s.
