Накратко на български
Барионните акустични осцилации и разпределението на галактиките се анализират чрез нови математически инструменти и симулации. Това помага за по-доброто разбиране на тъмната енергия и начина, по който се е формирала структурата на Вселената.

Baryonic Acoustic Oscilations as a Robust Probe for Dark Energy
Summary of project objectives: This project sought to find robust ways to constrain the cosmological model using future large- scale structure data sets. In particular, it sought to improve our understanding and modelling of galaxy clustering so that we may develop robust tests of the cosmological model and in particular tests for Dark Energy. The main scientific objectives were: 1. Develop new analytic tools and estimators that enable us to accurately interpret galaxy clustering data. The important systematics to control are: I. the nonlinear evolution of the mass density distribution; II. the nonlinear scale-dependent biasing of galaxies with respect to the mass; III. the nonlinear scale-dependent redshift space distortions. 2. Generate a large ensemble of large volume hi-resolution N-body simulations to rigorously test the advances in our understanding. 3. Develop theoretical and numerical tools to explore the importance of the light-cone effect for large-scale structure tests from future surveys. 4. Understand how large-scale structure tests, such as the BAO signal and shape of the galaxy power spectrum, might also help us to understand the primordial seeds of structure.

Цел на проекта
This research proposal focuses on the Baryonic Acoustic Oscillation signature in the low-redshift clustering of galaxies as a test for Dark Energy. Two vigorous lines of research are outlined. These are aimed at the challenge of readying this test and the other Large-Scale Structure tests of cosmology, for the era of percent-precision. This proposal also seeks funding to support the PI during their period of reintegration into the European scientific community. These funds will help the PI to maintain their recognised leadership in this area and to widely interact with their new European colleagues at the highest levels. It will further enable them to maintain strong ties with their trans-Atlantic partners in the US. This funding therefore offers the potential for encouraging closer long-term interaction between some of the best researchers in Europe and the US.
