Supermassive Black Holes

An artistic representation of what a giant cosmic jet the size of the distance between the Milky Way and Andromeda could look like (image for illustrative purposes only).

Cosmic Monsters in Plain Sight: Massive Radio Galaxies May Be More Common Than We Thought

The hidden centre of galaxy NGC 1052 (artist’s impression). In this artist’s impression we are nearing the supermassive black hole at the centre of galaxy NGC 1052. Here, material collects in a spinning disk before falling into the black hole, and magnetic fields build up which may help launch the galaxy’s powerful jets.

Simulation of the light emitted by a supermassive black hole binary system where the surrounding gas is optically thin (transparent). Viewed from 0 degrees inclination, or directly above the plane of the disk. The emitted light represents all wavelengths.

This illustration depicts two quasars in the process of merging. Using both the Gemini North telescope, one half of the International Gemini Observatory, which is supported in part by the U.S. National Science Foundation and operated by NSF NOIRLab, and the Subaru Telescope, a team of astronomers have discovered a pair of merging quasars seen only 900 million years after the Big Bang. Not only is this the most distant pair of merging quasars ever found, but also the first confirmed pair found in the period of the Universe known as Cosmic Dawn.

This image, taken by the Very Long Baseline Array (VLBA), shows two supermassive black holes, which appear as the blobs with red strips. The black holes are in the center of an elliptical galaxy. Colors represent different spectral slopes in radio emission, with red showing the most dense regions surrounding the black holes. The black hole on the right has likely recently devoured a massive star, which caused it to shoot out two ultrafast jets. The ends of those jets appear as green blobs above and below the black hole. This object, called J0405+3803, is referred to as a Compact Symmetric Object (CSO), because its jets are relatively close-in (or compact), compared to other black holes with much larger jets.
