Galaxies & CosmologyTurbulence and Star Formation Suppression in Elliptical Galaxies: The Role of Active Galactic Nucleus Jet Wind Interaction
AGN feedback effectively suppresses star formation in elliptical galaxies only when both jets and winds interact, generating turbulence via Kelvin-Helmholtz instability.
