Description
English: Lensing by a black hole. Animated simulation of gravitational lensing caused by a Schwarzschild 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 : Effet de lentille gravitationnelle causé par un trou noir : animation simulant une lentille gravitationnelle causée par un trou noir de Schwarzschild passant devant une galaxie en arrière-plan. Une image secondaire de la galaxie se forme à l'intérieur de l'anneau d'Einstein apparaissant sur la face du trou noir opposée à la galaxie. À mesure que l'image primaire se rapproche du trou noir, l'image secondaire grossit, toujours à l'intérieur des limites de l'anneau d'Einstein. La brillance de surface des deux images reste constante, mais leur taille angulaire varie, ce qui amplifie la luminosité de la galaxie vue par un observateur éloigné. L'amplification atteint son maximum lorsque la galaxie (ou comme ici, une de ses parties brillante) et l'observateur se retrouve exactement opposés l'un à l'autre par rapport au trou noir (c'est à dire en alignement parfait).
Nederlands: Zwaartekrachtlenseffect veroorzaakt door een zwart gat dat een achterliggend melkwegstelsel passeert. Rond het zwart gat is een Einsteinring te zien tegenover de richting van het stelsel
Українська: Модель гравітаційної лінзи (чорна діра проходить повз галактику, викривляючи її зображення).
