Scientific Rationale

What matters around galaxies? To tackle this question, this conference will bring together the leading experts of studies of the intergalactic and circumgalactic medium (CGM), using different methodologies (analytic theory, numerical simulations, observations) and tracers (from radio to optical, to X-ray). Specifically, we aim to discuss the following key questions:

  1. What is the origin and fate of the CGM?
  2. What are the morphological and physical properties of the CGM?
  3. What are the physical processes that shape the CGM on both large (kpc) and small (pc) scales?
  4. What is the relation between the CGM and galaxy properties?
  5. How does the CGM evolve and what can we learn by comparing different epochs and tracers?

Contributions in the form of long and short presentations centred on the above questions will aim to sketch a view of the current status of the field, and will highlight the principal open issues that future simulations and multiwavelength observations will need to address.
