OUR BEAUTIFUL UNIVERSE: Jets get a turbo boost

 OBU-jetsMerging galaxies. (X-ray: NASA/CXC/SAO/R van Weeren et al. Optical: NAOJ/Subaru. Radio: NCRA/TIFR/GMRT)

 

This image combines X-ray data from NASA’s Chandra X-ray Observatory with radio imagery from the Giant Metrewave Telescope in India and optical data from Japan’s Subaru telescope in Hawaii, in a field of view about 8 light years across. It shows merging galaxy clusters Abell 3411 and Abell 3412. X-ray emission (blue) indicates gas at several million degrees, moving towards the top right of this image. Radio emission (pink) tracks shocks from the collision. A jet from a supermassive black hole (centre left) is connected to the swirls of radio emission, indicating enhanced particle acceleration. Inflowing gas accelerated into a jet is then accelerated again at the shock. The results were presented at the American Astronomical Society meeting in January 2017 and published in Nature Astronomy by van Weeren et al.

This image is published in the February 2017 issue of Astronomy & Geophysics.
