Arthur Congdon earned a B.S. in Physics from Temple University in 2001, and a Ph.D. in Physics from Rutgers University in 2008. He was a fellow of the NASA Postdoctoral Program based at the Jet Propulsion Laboratory from 2008-2010.

Charles Keeton earned a B.A. in Physics from Cornell University in 1994, and a Ph.D. in Physics from Harvard University in 1998. He held the Bart J. Bok Fellowship at the University of Arizona and a NASA Hubble Fellowship at the University of Chicago before joining the faculty of Rutgers University in 2004.

Congdon wrote his doctoral thesis on gravitational lensing under Keeton's supervision. Here they use their combined expertise to explain many physical and astrophysical aspects of the topic.
