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.

    The Venue

    The conference will be held in the Ogden Centre West building, recently completed in October 2016. This is on the Durham University Science site next to the main Physics Department.
    The nearest airport is Newcastle Airport (about 40min-1hr by taxi) and the nearest train station is in Durham City centre (25 min walk or a 5 min taxi ride).

    For more information, see the Physics Department guide.

    Places to Stay

    There will be a block of rooms at Durham hotels for the conference. More information to come soon.

    Places to eat and drink

    Additional information coming soon.

    Pre-registration and abstract submission

    Please fill out the below form to be pre-register for the conference. We'll ask for final registration and payment of conference fees once the program has been finalised.
    Participants will be limited to approximately 90 people, so early pre-registration is highly recommended.

    As part of your abstract, please reference which of the key questions from our Scientific Rationale you plan to address in your contribution.

    You should receive a confirmation e-mail shortly after submitting this form. If you don't, or if any of the information is incorrect, please contact us at the conference e-mail: what.matters@durham.ac.uk.
