#MicRoleNsing

Strong gravitational lensing and microlensing of supernovae (SNe) are emerging as a new probe of cosmology and astrophysics in recent years. We provide an overview of this nascent research field, starting with a summary of the first discoveries of…

In December 2019, astronomers detected a one hour brightening of a star in the Large Magellanic Cloud, a classic gravitational microlensing event. These occur when a compact object bends a distant the light of a distant star as it passes in front of it.…

Astronomers have long known that neutron stars, the crushed cores left behind after massive stars explode, should be scattered throughout the Milky Way
