Location:  Thessaloniki, Greece

Scientific Topic and Scope:
Over the last few years there have been repeated claims of dipolar anisotropies in a variety 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 relatively 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 workshop will review the above mentioned issues, both from the observational and from the theoretical viewpoint, it will consider possible explanations and will discuss their potential implications for the future of cosmological research.
