Rutgers professor Saurabh Jha was a graduate student on a team led by today's Nobel Prize in Physics winner Brian Schmidt, who shares half of the prize with Adam Riess, lead author of the seminal report on the expansion of the galaxy (Astronomical Journal, v. 116, p. 1009, 1998).
Team members observed bright exploding stars at the edges of the universe, gauging how far away they were and how fast they were receding, reaching the conclusion that the universe is continuing to expand. Since then, Jha has continued to work on observing these exploding stars, called type 1a supernovae, measuring their distance and speed with increasingly higher precision. His work has contributed to the confidence that scientists have in the conclusions drawn from that original 1998 study.
