ALMA and MUSE Detect Galactic Fountain

Composite image of the Abell 2597 galaxy cluster showing the fountain-like flow of gas powered by the supermassive black hole in the central galaxy. The yellow is ALMA data showing cold gas. The red is data from the MUSE instrument on ESO’s Very Large Telescope showing the hot hydrogen gas in the same region. The blue-purple is the extended hot, ionized gas as imaged by the Chandra X-ray Observatory.

The yellow ALMA data shows infalling material and the red MUSE data shows material launched in a vast spout by the black hole.
