The Einstein ring is a special case of the gravitational lensing effect. It occurs when light from a more distant light source, aligned with a massive celestial object (such as a galaxy or a black hole), is bent by the gravitational influence of this object, resulting in the light appearing as a perfect ring in the observer's field of view. This phenomenon is one of the predictions of the theory of relativity and was first theoretically expressed by Albert Einstein in 1936. Physical Basis Einste

ESO 325-G004 Galaxy is a massive elliptical galaxy located approximately 450 million light-years from Earth in the constellation Centaurus. It was first classified during observations conducted by the European Southern Observatory (ESO). The galaxy is particularly notable for serving as an example of gravitational lensing phenomena. This feature has led to its use as a model system in various studies aimed at understanding the distribution of dark matter and the matter density in the universe. P
