Rationale

 

During the past 20 years there has been a resumption of a dialogue between astronomers and statisticians. This dialogue has been fruitful and has been the origin of a new discipline that is now widely called Astrostatistics. The main tools for comparing theoretical results with observations in astronomy are statistical. However, the development of huge astronomical databases presents challenges of scale, and has initiated an active use of newly-developed statistical techniques in astronomy, notable examples being sparsity and compressed sensing.

The meeting is especially timely from the point of view of cosmological surveys, where the size makes application of a fully Bayesian analysis computationally extremely demanding, especially in the realm of model selection. Pan-STARRS will have a complete survey of 3π steradians of petabyte size; the Dark Energy Survey and the VST KiDS surveys will be well underway presenting similar difficulties in the data analysis. Moreover, the cosmological community will be preparing for LSST and for Euclid, a survey of a large fraction of the sky at an angular resolution close to that of the Hubble Space Telescope. Wide-field spectroscopic cosmology surveys of will be targeting over 10 million objects with a spectral resolution of 5000, with the SKA precursors will be grappling with data challenges which currently are unsolved. These examples also highlight the big current role and even bigger future role of archival data in astrophysics research.

The Cosmo21 conference is organised in conjunction with the 9th edition of the Astronomical Data Analysis (ADA9) summer school, which aims to provided younger researchers with technical skills required to deal with modern data.

  2. Be respectful. We endeavour to provide a safe, comfortable and professional work environment. Participants should be courteous with the opinions of others and be mindful not to exclude anyone from discussions or work-related activities. In particular, participants should avoid making derogatory comments or jokes that may be damaging to the career prospects of others.
  3. All communication should be appropriate for a professional audience including people of many different backgrounds. Racist, sexual or sexist language and/or imagery is not appropriate.

Participants asked to stop any inappropriate behaviour are expected to comply immediately. Attendees violating these rules may be asked to leave the meeting at the sole discretion of the organisers. Any participant who wishes to report a violation of this policy is asked to speak, in confidence, to Samuel Farrens (samuel.farrens@cea.fr) and/or Valeria Pettorino (valeria.pettorino@cea.fr) who will be in-place during the conference.
