Astronomers Detect Black-Hole Jets in Central Galaxy of Phoenix Cluster

The distorted galaxy in the simulation (main image) results from a collision and merger between two galaxies. Astronomers think such a merger could be the reason why SPT0346-52 is having such a boom of stellar construction. Once the two galaxies collide, gas near the center of the merged galaxy (shown as the bright region in the center of the simulation) is compressed, producing a burst of new stars. The composite inset shows X-ray data from Chandra (blue), short wavelength infrared data from Hubble (green), infrared light from Spitzer (red) at longer wavelengths, and infrared data from ALMA (magenta) at even longer wavelengths. There is no blue at the center of the image, showing that Chandra did not detect any X-rays that could have signaled the presence of a growing black hole.
