X-ray, Optical & Radio Images of Phoenix Cluster
New observations of the galaxy cluster SPT-CLJ2344-4243 (or Phoenix Cluster) at X-ray, ultraviolet, and optical wavelengths are helping astronomers better understand this extraordinary system. Chandra data reveal large cavities in the X-rays, which are shown with optical data from Hubble. Astronomers think these X-ray cavities were carved out of the surrounding gas by powerful jets of high-energy particles emanating from near a supermassive black hole in the central galaxy of the cluster. Massive filaments of gas and dust, which extend for 160,000 to 330,000 lights years, surround the X-ray cavities.
