AGN FEEDBACK ACROSS ALL SCALES AND TIME

6 - 10 JULY 2026

GARCHING NEAR MUNICH, GERMANY

 

AGN feedback is a complex problem. It involves multiple spatial scales, multiple physical processes, multiple gas phases 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 ever-more-detailed cosmological simulations. Observationally, great progress has been made in characterizing the demographics of AGN driven outflows and jets using Integral Field Spectrographs from the ground and sub-mm and radio interferometers. JWST in the last two years has opened a new window in these studies allowing to trace completely new regime of gas phases with unprecedented detail thanks to its sensitivity and coverage of the mid-infrared regime.

All this theoretical and observational effort has increased our understanding of feedback phenomena, but it has also opened many new exciting questions. The main aim of the workshop is to tackle these open questions bringing together experts on AGN feedback studies. We believe the time is very appropriate for such a meeting to summarize where we stand and plan future lines of research in this very important field. The proposed workshop also aims at putting AGN feedback studies in the context of current, future and concept facilities (LSST, Euclid, MOONS, PSF, Roman, 4MOST, SKA, ELT, LISA, ngVLA, New Athena, etc..).

We foresee that the workshop will focus on the following key questions:

  • How do we robustly trace and test the AGN feedback process from parsec to megaparsec scales?
  • What is the relative impact of AGN feedback on ISM and CGM scales?
  • What are the key properties of multiphase outflows (e.g. mass loading, velocities, etc.) that allow a meaningful comparison between observations and simulations?
  • How do different driving mechanisms (e.g. winds, jets, radiation) operate as a function of SMBH properties, galaxy properties or cosmic time?
  • What is the impact of the AGN feedback in the early formation of SMBHs and galaxies during the reionization epoch?
  • Which major advancements are needed in numerical simulations of AGN feedback?

 

We invite you to join us for this workshop at the ESO Headquarters in Garching near Munich, with remote participation available via MS Teams.
