A funky effect Einstein predicted, known as gravitational lensing — when a foreground galaxy magnifies more distant galaxies behind it — will soon become common when NASA’s Nancy Grace Roman Space Telescope begins science operations in 2027 and produces vast surveys of the cosmos.
Strong lenses are the focus of a new paper published in the Astrophysical Journal, led by Bryce Wedig, a physics graduate student in Arts & Sciences at Washington University in St. Louis.
