Astronomers Spot ‘Flickering’ Supermassive Black Hole

This image shows the SDSS J1354+1327 galaxy in a composite image with data from Chandra (purple), and Hubble (red, green and blue). The inset box contains a close-up view of the central region around SDSS J1354+1327’s supermassive black hole. The larger companion galaxy, SDSS J1354+1328, is shown to the north.

A rapidly growing supermassive black hole — known as an active galactic nucleus — in the center of a distant galaxy appears to have consumed large amounts of gas while blasting off an outflow of high-energy particles. The outflow eventually switched off then turned back on about 100,000 years later. This image shows the SDSS J1354+1327 galaxy in a composite image with data from Chandra (purple), and Hubble (red, green and blue). The inset...

This image from the NASA/ESA Hubble Space Telescope shows ACT-CLJ0102-4915. Massive galaxy clusters such as ACT-CLJ0102-4915 are useful tools for studying very distant objects, because this lens-like behavior amplifies the light from faraway galaxies in the background. They also contribute to a range of topics in cosmology, as the precise nature of the lensed images encapsulates information about the properties of spacetime, the expansion of the cosmos and the distribution of dark matter within the cluster.
