West Coast Swings

Exploring the Connection Between the Cosmic Web and Galaxy Evolution for Next Generation Surveys

26-30 March 2018
Trinity College, Universit of Western Australia, Perth, WA, Australia

In standard cosmology, small fluctuations of matter density in the early Universe led to the formation of the “cosmic web” that we observe in large spectroscopic surveys and simulations today. This structure conditions the geometry and dynamics of gas flows from early times onwards: gas trapped in collapsed dark matter halos is funneled through cold filamentary streams shaped by the cosmic filaments and advected towards the centre of forming galaxies to which it transfers part of its angular momentum. Over cosmic time, as gas rarefies the environment evolves through small-scale processes including hydrodynamic instabilities or AGN and supernovae feedback. This also affects drastically the morphology and internal dynamics of galaxies. Next generation telescopes, such as the Square Kilometre Array (SKA) in Australia, combined with ongoing and upcoming Integral Field Spectroscopy (IFS) surveys such as SAMI (Anglo-Australian Observatory) or MUSE on the VLT promise to probe the gas dynamics on a sufficiently wide range of scales to analyze such multi-scale interactions between galaxies and cosmic filaments. This will transform our current understanding of how galaxies form and evolve with their environment, which is identified as a major science case for next-generation facilities such as the SKA.

The workshop will consist of two days of conference-style lectures followed by three days of hands-on workshop segmented in sessions dealing with specific projects. Projects will include the production of mocks for upcoming surveys, the development of inverse methods to relate galactic spins to the archaeology of cosmic flows and analysing the fate of collimated gas flows infalling from cosmic filaments onto clusters of galaxies.

Travel and Accommodation

Participants will arrange their own travel and accommodation; however, we list here some relatively convenient options in the general vicinity of the workshop venue.

All travellers other than Australian and New Zealand citizens need a valid visa or authority to enter Australia (including electronic visas).  Please contact the organisers if you need a letter of invitation for your visa application. For some nationalites, processing and issuance of visas can take several weeks/months, so apply well before your planned travel.

Childcare

Childcare will be available for infants and children under 5.  Please indicate in your registration if you require childcare or contact Clare Peter (clare.peter@uwa.edu.au) if you have any questions.

Accessibility

If you have any access requirements in order to participate in this workshop please note them in your registration form or contact Clare Peter (clare.peter@uwa.edu.au) directly with any questions.
