AGN feedback is a complex problem. It involves multiple spatial scales, multiple gas phases and mass scales, multiple physical processes and timescales. Recent progress has been accelerated by an increase in both computational developments and observational facilities. The past years have witnessed the dawn of a new range of sub-grid models for AGN feedback, incorporated into...

49. Blue LERGs and a Missing Evolutionary Axis in Radio-AGN Unification: Small-Scale Jets, Mergers, and Warm Molecular Gas

Blue low-excitation radio galaxies (BLERGs) may expose a missing evolutionary axis in radio-AGN unification. In the canonical picture, low-excitation radio galaxies are powered by radiatively inefficient accretion in massive, quiescent hosts, where mechanical feedback suppresses cooling and star formation. BLERGs break this expectation: they retain ongoing star formation and substantial...

63. The Properties and Morphology of Highly Ionized Coronal Line Outflows in Nearby Jetted AGN

Regular

Active galactic nuclei (AGN) drive multiphase outflows via both radiative and jet modes. While these outflows are extensively studied using traditional tracers—such as [O III] for ionized gas and H₂ or CO for molecular gas—and ultra-fast outflows (UFOs) are identified via extreme X-ray absorption, the intermediate-to-high ionization phase remains poorly understood. This regime (up to $\sim...
