A Systematic Search for Active Galactic Nucleus Flares in ZTF Data Release 23
Active galactic nuclei (AGNs) are known to exhibit stochastic variability across a wide range of timescales and wavelengths. AGN flares are extreme outbursts that deviate from this typical behavior and may trace a range of energetic physical processes ...

The Contribution of Turbulent Active Galactic Nucleus Coronae to the Diffuse Neutrino Flux
Active galactic nuclei (AGN) can accelerate protons to energies of ∼10–100 TeV, with secondary production of high-energy neutrinos. If the acceleration is driven by magnetized turbulence, the main properties of the resulting proton and neutrino spectra ...

How Quasar Feedback May Shape the Co-evolutionary Paths
Observations point toward some form of “co-evolutionary sequence,” from dust-enshrouded starbursts to luminous unobscured quasars. Active galactic nucleus (AGN) feedback is generally invoked to expel the obscuring dusty gas in a blow-out event ...

ACTIVE GALACTIC NUCLEUS FEEDBACK IN THE HOT HALO OF NGC 4649
Using the deepest available Chandra observations of NGC 4649, we find strong evidences of cavities, ripples, and ring-like structures in the hot interstellar medium that appear to be morphologically related with the central radio emission. These structures show no significant temperature variations in correspondence with higher pressure regions (0.5 ...
