Over the last several years, the departure of the CMB from exact Gaussianity has become one of the best measured parameters in cosmology. The imminent launch of the Planck satellite, coupled with surveys of large-scale and 21cm emission, mean that non-Gaussianity is become a focal point for the confrontation between observation and fundamental theory. The time is right to draw together the experimental groups who are currently searching for signatures of non-Gaussianity and the theorists who are predicting what can be observed. There is an extraordinary opportunity to discover new and exciting physics over the next few years.

The aims of this Astrosim/CTC workshop are:

  1. To map out in detail what we can expect from Planck and other experimental probes.

  2. To refine the tools with which predictions of non-Gaussianity can be made from concrete models, particularly intensive computational aspects.

  3. To explore scenarios in fundamental physics which can give testable signatures, such as brane inflation models and cosmic defects.

This workshop aims to bring together many of the world's leading researchers actively working on non-Gaussianity in cosmology. The workshop will be immediately followed by a Planck Consortium Working Group 4 (Non-Gaussianity) meeting on Thursday 11th September also in Cambridge. Further information to follow.

The workshop programme aims to maximise opportunities for interactions between all participants, with relatively short invited contributions leaving plenty of time for questions and further discussion. A preliminary schedule is now available on the Programme page. The meeting will begin after lunch on Monday 8th September 2008 and end formally at the end of Wednesday 10th September, but there will be the opportunity to stay on at the Centre for Mathematical Sciences for further informal discussions/collaboration. On Thursday 11th September there will be a Planck meeting on Non-Gaussian projects (a.m.)

*To be confirmed.

The workshop venue is the Centre for Mathematical Sciences, the award-winning buildings that have housed the Department of Applied Mathematics and Theoretical Physics since 2000. With its excellent facilities and good transport connections to international airports, the CMS has an excellent track record hosting international conferences. Talks will take place in the main lecture hall (MR2) with lunches served upstairs in the central core (pictured right), a pleasant setting for research interactions. Workshop participants will be housed nearby in a modern Cambridge college, Lucy Cavendish College (or Wolfson Court). For local maps and further information refer to the Location page, while transport instructions can be found under Travel.

The local organising committee for this meeting consists of

Michele Liguori
Carlos Martins
David Seery
Paul Shellard
Kendrick Smith

The meeting is being run under the auspices of the new Cambridge Centre for Theoretical Cosmology (CTC) housed in DAMTP which is generously supported by the Stephen Hawking Endowment for Cosmological Research. Because of the highly computational nature of work on Non-Gaussianity, we are also seeking support from the ESF Astrosim network.
