Single Workshop

Abstract

How can we optimally exploit present and future large scale structure surveys to address questions about the nature of the Dark Energy, and to test the Standard Model of Cosmology and the Theory of Gravity on large scales?

In the next decades, we plan to continue the success story of the CMB with observations of CMB polarisation and to go beyond with surveys of the large scale structure of the Universe. The potential of large scale structure surveys is substantial as they deliver three dimensional data sets, i.e. we can observe the large scale structure at many different redshifts. The new generation of observations are already starting with the currently active Dark Energy Survey (DES), and they continue with upcoming data of the SDSS survey and especially with data of the Euclid satellite (to be launched in 2020), the large synoptic survey telescope (LSST) and the Square Kilometer Array (SKA) radio telescope.

The purpose of this meeting is to bring together theoretical and observational cosmologists to take stock of the current state of the field and to look forward to the next generation of surveys.

Topics

- Inflation and the Early Universe,
- Dark Energy, Dark Matter and Modified Gravity,
- Testing General Relativity with LSS surveys,
- Large-scale Surveys: observables, forecasts and methodology, from data to theory,
- The Cosmic Microwave Background: polarisation and anisotropies.

General Program

The 3rd and 6th weeks of the workshop will be two focus weeks on, respectively, LSS theory and dark energy / modified gravity models, while the 7th week will be dedicated to the workshop conference. During these two focus weeks there will be a large concentration of talks, while we plan a more light schedule for the rest of the workshop, allowing plenty of time for discussions and collaborations.

Poster session

The participants who would like to present a poster are kindly invited to send an email with the title and a short abstract to alice.bernamonti@unifuit before May 22, specifying for which week of the workshop. Since a limited number of panels is available, the organizers will select the posters shortly after the deadline.

11 Apr, 2016 - 15:00-	Albert Stebbins	Reserve Engineering Space-Time	Seminar	Abstract A major aspect of modern observational cosmology is determining the geometry of space-time. Evidence for dark matter and "dark energy" are really statements about space-time geometry. Focusing on geometry circumvents questions of whether these phenomena are caused by exotic matter or modifications of gravity. It is shown how geometry can be simply expressed in terms of observable quantities, some of which are currently in use for cosmology, and some of which we can expect to use in coming decades. This analysis reveals glaring holes in our direct measurement of geometry and it is shown how these holes have been filled in by other assumptions about our universe.
