    ASU astronomers uncover black hole jets reaching far beyond their galaxies and deciding their fate
    Artist’s illustration of a supermassive black hole at the center of a radio galaxy launching powerful jets (shown in pink) all the way into the galaxy’s CGM. The study finds that these jets do not light up the surrounding gas equally in all directions. Instead, the hydrogen gas glows (shown in red) most strongly along the path of the radio jets. This suggests that black holes can send energy far beyond the galaxy’s center and shape the larger gas reservoir that regulates star formation and fate of galaxies. We use optical data from the DESI survey and radio observations from the LOFAR Two meter Sky Survey (LoTss). Credit: Hailey Nelson/ Arizona State University.

    Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas...
