==Awards== * 2007: [[Gruber Prize in Cosmology]] (co-recipient with [[High-z Supernova Search Team]]) * 2011: [[Nobel Prize in Physics]] was awarded to Leibundgut's colleagues [[Brian P. Schmidt]] and [[Adam Riess]], from the [[High-z Supernova Search Team]] for the work done by that collaboration. * 2015: [[Fundamental Physics Prize|Breakthrough Prize in Fundamental Physics]], shared with [[Brian P.
