Astronomers in California used adaptive optics (AO) to pinpoint the exact location of a pair of supermassive black holes at the center of a collision of two galaxies. The study of the galaxy merger, ...

Adaptive optics (AO) is a technique used for real-time correction of phase aberrations by employing feedback to adjust the optical system. Polarization aberrations represent another significant type ...
