Extreme magnification of a star at redshift 1.5 by a galaxy-cluster lens
Patrick L. Kelly, Jose M. Diego, Steven Rodney +42
Galaxy-cluster gravitational lenses can magnify background galaxies by a total factor of up to ~50. Here we report an image of an individual star at redshift z=1.49 (dubbed "MACS J…
