An article published in “The Astrophysical Journal” describes the observation of a sort of galactic fountain of cold molecular gas pumped by a supermassive black hole in the brightest galaxy of the galaxy cluster Abell 2597. A team of researchers used the ALMA radio telescope and the MUSE spectrograph mounted on ESO’s VLT to observe for the first time a cycle that includes both inflow and outflow that powers that fountain.
