Cloverleaf quasar
Videos
The Cloverleaf quasar is a bright, gravitationally lensed quasar discovered by Hazard, Morton, Terlevich and McMahon in 1984. It receives its name because of gravitational lensing splitting the single

Einstein ring

An Einstein ring, also known as an Einstein–Chwolson ring or Chwolson ring, is created when light from a galaxy or star passes by a massive object en route to the Earth. Due to gravitational lensing,

…around the black hole has been detected suggesting outflow wind. Data from NICMOS and a special algorithm resolved the lensing galaxy and a partial Einstein ring. The Einstein ring represents the host galaxy of the lensed quasar. The Cloverleaf quasar was discovered in 1988. Data on the Cloverleaf collected by…
