Galaxies Akira and Tetsuo

Red Geyser Galaxy

An artist’s rendition of the galaxies: Akira (right) and Tetsuo (left) in action. Akira’s gravity pulls Tetsuo’s gas into its central supermassive black hole, fueling winds that have the power to heat Akira’s gas. The action of the black hole winds prevents a new cycle of star formation in Akira. (Credit: Kavli IPMU)
