Powerful Outflows and Feedback from Active Galactic Nuclei

abstract
Active Galactic Nuclei (AGN) represent the growth phases of the supermassive black holes in the center of almost every galaxy. Powerful, highly ionized winds, with velocities $\sim 0.1- 0.2c$ are a common feature in X--ray spectra of luminous AGN, offering a plausible physical origin for the well known connections between the hole and properties of its host. Observability constraints suggest that the winds must be episodic, and detectable only for a few percent of their lifetimes. The most powerful wind feedback, establishing the $M -\sigma$ relation, is probably not directly observable at all. The $M - \sigma$ relation signals a global change in the nature of AGN feedback. At black hole masses below $M-\sigma$ feedback is confined to the immediate vicinity of the hole. At the $M-\sigma$ mass it becomes much more energetic and widespread, and can drive away much of the bulge gas as a fast molecular outflow.

XRISM/Resolve data on Mrk 509 show a tentative 3.6-sigma infalling absorber at 11000 km/s located within thousands of gravitational radii, interpreted as raining clumps from a failed wind.
A JWST census detects neutral ISM absorption in 76 of 309 galaxies at 0.6<z<4 and outflows in 26, indicating AGN-driven neutral outflows dominate in quiescent systems at cosmic noon.
AGN radiation pressure, not black-hole mass, simultaneously boosts large-scale [O III] outflows and clears circumnuclear gas as Eddington ratio rises.
The quasar J1512+4422 at z~6.2 lies on the local M_BH-σ_* relation and powers an outflow whose mass and energy loss rates exceed the host's star formation rate, indicating negative feedback.
Larger black holes in TDEs accrete more material and launch faster winds, with unbound mildly relativistic winds for higher viscosity parameters and bound convective outflows for lower ones.
FIRE-2 simulations find metallicity gradients in EoR galaxies flatten from median -0.15 dex/kpc at z~10 to -0.1 at z~6, with positive correlations to stellar mass and gas flow proxy Δv/2σ and links to central SFR density.
TNG50 shows galactic outflow mass loading is non-monotonic with stellar mass, rising rapidly above 10^10.5 Msun due to black hole feedback, and produces fast multi-phase outflows with emergent collimation.
In the SUBWAYS sample, UFO-hosting AGN show larger radio extent and steep spectra consistent with wind-driven shocks, while ~80% of sources show outflow-like radio emission.
Simulations demonstrate that a retrograde IMBH with mass ratio ~0.67 to the disc mass fragments a stellar disc into inner, misaligned, and outer components within 10-20 Myr.
Citizen science discovery of a bow-and-arrow radio galaxy with ~560 kpc bow-shock-like structure in a multi-halo environment at z=0.159.
Simulations show observationally selected protocluster candidates at z ≳ 5 include significant interlopers, undergo 2-6 major mergers, and exhibit stronger clustering than observed, requiring total galaxy mass within 10 cMpc for reliable progenitor identification.
Variable column density and covering factor of three ionized absorbers in clumpy disk winds explain the X-ray variability in I Zw 1 with stable corona.
JWST spectroscopy reveals radio jets in nearby AGN drive multiphase ISM turbulence and shock-dominated H2 excitation both along and perpendicular to the jet direction.
NOEMA CO(2-1) data show a nuclear molecular outflow in NGC 3079 offset by 14 pc with velocities -350 to -450 km/s, mass outflow rate 8.82 M_sun/yr, kinetic power 3.8e41 erg/s, and momentum rate 15 times the AGN radiation momentum, indicating an energy-driven jet-powered outflow.
New ALMA [C II] and FIR data on PSO J083+11 at z=6.34 reveal ordered rotation, typical star-forming ratios, and no outflow signatures in either galaxy, interpreted as a pre-AGN-feedback accretion phase.
Multi-phase molecular gas in IRAS20551-4250 is dominated by cold CO, shows UV-heated warm H2, tidal features from a merger, and no molecular outflows, consistent with ongoing star formation.
Calibrated AGN disk-wind models contribute ≲5% to the CGB above 10 GeV and ≲10% to the CNB at 100 TeV and are unlikely to dominate either background.
Modeling of jets escaping AGN disks reveals distinct nonthermal emission signatures that support multi-messenger detection and diagnostics of the AGN environment.
A model of accretion-disk dynamos as synchronized macro-spins unifies broadband variability, coronal heating, jets, and hard/soft cycles via collective spin dynamics.
Next-generation CMB experiments are expected to detect thousands of strongly lensed galaxies to z~6 and proto-clusters, plus tens of thousands of local dusty galaxies and radio sources, enabling new studies of galaxy formation.
SKA-mid AA4 will enable deep, spatially resolved HI imaging over hundreds of square degrees at column densities down to 10^18 cm^{-2} to study environmental gas processes from isolated galaxies to clusters.
SKAO will trace synchrotron jets, thermal emission, and low-column-density HI gas in nearby AGN to characterize duty cycles and multi-phase feeding/feedback linked to star formation.
A review of AGN unification concluding that whether a black-hole-powered nucleus appears obscured depends on inclination, Eddington ratio (radiative feedback), and host-galaxy merger/redshift evolution.
