A precessing jet from an active galactic nucleus drives gas outflow from a disk galaxy

Justin A. Kader, Vivian U, Loreto Barcos-Muñoz +30

To reproduce observed galaxy properties, cosmological simulations require that massive galaxies experience feedback from active galactic nuclei, which regulates star formation with…
