Scientific Rationale

In the era of multiwavelength astrophysics and exascale computing, we are approaching a unified understanding of black hole feeding and feedback across cosmic time. The ERC-funded BlackHoleWeather collaboration aims to uncover how supermassive black holes (SMBHs) self-regulate their host galaxies, groups, and clusters through complex, multiphase gas dynamics — akin to Earth-like weather, but on cosmic scales.

From hot X-ray halos to ionized, neutral, and molecular filaments, the baryonic atmosphere is both shaped and stirred by the central SMBH. Chaotic cold accretion, turbulence, magnetic fields, cosmic rays, and AGN-driven outflows interweave across scales ranging from the black hole horizon to the virial radius. With next-generation instruments such as JWST, XRISM, ALMA, MUSE, MeerKAT, and NewAthena, along with cutting-edge GPU simulations, we are poised to forge the crucial links between microphysics and galaxy-scale evolution.

This focused winter meeting will bring together a select group of theorists, observers, and computational experts to advance our understanding of the self-regulated loop of precipitation, feeding, and feedback across cosmic structures. The format will emphasize deep discussion, collaborative planning, and interactive sessions, including topics such as:

  • Macro-to-micro scale connection: from Mpc halos to Schwarzschild radii – and vice versa
  • Condensation and accretion modes: hot vs. cold, chaotic vs. smooth feeding
  • Outflow physics: from ultrafast winds to molecular outflows and radio jets
  • Turbulence, MHD, cosmic rays, and energy transport
  • Dusty clouds, star formation, and their interplay with BH activity
  • Comparing multiwavelength observations (X-ray, radio, optical, IR) with simulations

Ample time will be dedicated to open-format discussions, brainstorming sessions, and the planning of future simulation campaigns and observing programs aligned with the BlackHoleWeather framework. The goal is to solidify emerging collaborations and chart the course for a new generation of high-resolution, multi-physics models of cosmic weather driven by black holes.
