XMM-Newton SOC at ESAC

The symposium is the sixth meeting in the series "The X-ray Universe". It is intended to encompass a broad range of high energy astrophysics topics and provide a showcase for results and discoveries not only from XMM-Newton but also from other current missions. In addition, the scientific potential of future projects will be discussed at the conference.

Over the last few years, there have been repeated claims of dipolar anisotropies in a number of cosmological observations. These include dipoles in the number counts of distant astrophysical objects, like quasars and radio galaxies for example, as well as dipoles in certain cosmological parameters, such as the Hubble and the deceleration parameter. In view of these reports, the emerging question is whether the associated observations reflect some underlying generic anisotropy of the universe we live in, whether they are late-time additions triggered by the ongoing process of structure formation in particular, or they are mere artefacts of our gross misinterpretation of the data. The aim of the workshop is to review the above-mentioned issues, both from the observational and from the theoretical point of view, to consider possible explanations, and to discuss their potential implications for the future of cosmological research.

The workshop is devoted to quantum spacetime and noncommutative geometry and the their connections to various branches of research, including strings and supersymmetry, field theory on noncommutative spaces, quantum symmetries and dualities, gravity and cosmology, fuzzy spaces and matrix models, higher homotopy structures in quantum field theory, particle and gravity phenomenology, integrable systems, quantum information and gravity, and black holes.
