The emphasis of the conference is on advances and methodological challenges in cosmology, and new results derived from advanced data analysis and modeling methods. Cosmology is entering a new area which will require processing of huge data sets, and measurements at the subpercent level of accuracy in order to answer fundamental cosmological questions such as the nature of dark matter, dark energy and gravity. As ever, statistics will inevitably play a fundamental role in understanding the new generation of data, but with additional challenges of everincreasing datasets and large parameter spaces.
Topics
 Cosmic microwave background: nonGaussianity, component separation methods.
 Weak lensing: galaxy shape measurements, projected mass density map reconstruction, threedimensional mapping of the dark matter, high order statistics, Euclid, LSST.
 Largescale structure
 High redshift supernovae.
 Mapping highz 21cm radiation
 Lymanalpha forest
 Astronomical discovery from overwhelmingly large datasets: BOSS, EUCLID, PAU, LAMOST, LOFAR, SKA, LSST and others.
 Statistical methods used in astronomical data analysis (including new developments coming from fertile crossinteractions in astrostatistics). A preliminary list of these methods is included below:
 Bayesian methods, evidence, model selection.
 Multivariate classiﬁcation and clustering.
 Sparsity: wavelets, compressive sampling, 2D and 3D data representations.
 Machine learning for large multivariate datasets: Kernel regression, Support Vector Machine, neural networks, supervised learning.
There will be several sessions during the conference. Each session will have at least one keynote speaker, and half of the talks will be contributed talks. The crossdisciplinary nature of the symposium is reflected in the inclusion of speakers from the statistics community in the suggested list.
