Enormous Black Hole Boosts Star Formation in Phoenix Galaxy Cluster

Nov 22, 2019 by News Staff

Supermassive black holes in the center of galaxy clusters usually suppress star formation, but the one in the Phoenix Cluster, a group of about 1,000 galaxies...

False-color and X-ray images of the giant arc in SPT-CLJ2344-4243: the X-ray-emitting giant arc is shown relative to the center of the foreground lensing galaxy cluster in a false-color image at optical wavelengths; the inset shows Chandra X-ray (left) and Hubble optical (right) images of the giant arc at a scale 1.5 times larger; the optical colors here are given by Hubble imaging data in the F850LP (red), F775W (green) and F475W (blue) filters; two magenta circles indicate the locations of the X-ray emission from the giant arc in both inset panels; the lensing geometry of the giant arc is a pair of merging images, where the lower and upper halves of the arc are each a single image with mirror symmetry.

Phoenix Cluster’s Gravity Magnifies X-Rays from Extremely Distant Star-Forming Galaxy

Oct 15, 2019 by News Staff

Astronomers have used a huge group of galaxies called the Phoenix cluster as a cosmic magnifying glass to detect X-ray emission from a very distant dwarf...

Composite image showing how powerful radio jets from the supermassive black hole at the center of a galaxy in the Phoenix Cluster inflated huge ‘bubbles’ in the hot, ionized gas surrounding the galaxy (the cavities inside the blue region imaged by NASA's Chandra X-ray observatory). Hugging the outside of these bubbles, ALMA discovered an unexpected trove of cold gas, the fuel for star formation (red). The background image is from the NASA/ESA Hubble Space Telescope.
