English: Animated simulation of gravitational lensing caused by a black hole going past a background galaxy. A secondary image of the galaxy can be seen within the black hole Einstein ring on the opposite direction of that of the galaxy. The secondary image grows (remaining within the Einstein ring) as the primary image approaches the black hole. The surface brightness of the two images remains constant, but their angular size varies, hence producing an amplification of the galaxy luminosity as seen from a distant observer. The maximum amplification occurs when the background galaxy (or in the present case a bright part of it) is exactly behind the black hole.
Français : Simulation animée de la lentille gravitationnelle causée par un trou noir passant en arrière-plan d'une galaxie. Une image secondaire de la galaxie peut être vue dans le trou noir de l' anneau d'Einstein dans la direction opposée à celle de la galaxie. L'image secondaire grandit (restant dans l'anneau d'Einstein) lorsque l'image principale s'approche du trou noir. La Brillance de surface des deux images reste constante, mais leur taille apparente varie, produisant ainsi une amplification de la luminosité de la galaxie vue d'un observateur distant. L'amplification maximale se produit lorsque la galaxie d'arrière-plan (ou, dans le cas présent, une partie brillante de celle-ci) est exactement derrière le trou noir. |
