sorae – There are 12!A galaxy that appears to be split by gravitational lensing
This was introduced by sorae in an article on November 8, 2019.Galaxy clusters and “sunburst arc galaxies”“is.
Near the center of this image of this galaxy cluster, located approximately 4.6 billion light-years from Earth, a partially interrupted arc-shaped object is visible. This arc is caused by the direction of light from a single galaxy further away than the galaxy cluster being bent by the “gravitational lensing” phenomenon caused by the gravity of the galaxy cluster.From Earth, it appears extremely distorted.Thing.
The galaxy that appears distorted isSunburst Arc galaxy” has been given the name. (Official name is “PSZ1 G311.65-18.48”).
In fact, the image of the sunburst arc galaxy is not only distorted by gravitational lensing, but also has at least 12 clones. A total of four arcs have been confirmed, but the upper arc from the center contains six images, the upper right arc contains four images, and the right and lower left arcs each contain one image. It is believed that
