Anisotropic Universe: From Microwaves to Ultrahigh Energies

The study of anisotropies connects and unravels fundamental issues in various fields of astrophysics and cosmology. With the recent experimental progress, it is now possible to analyse, understand, and cross-correlate the anisotropic skies observed by Planck, 2MASS Redshift Survey, Chandra, Fermi, AMS-2, HAWC, IceCube, and Auger — to cite but a few major instruments that scrutinize the Universe from microwaves to ultrahigh energies in photons, cosmic rays, and neutrinos. Anisotropic features can reveal key information on the structure and the nature of the components of the Universe, and provide hints on the origin of high energy emission.

In this workshop, instead of focusing on one particular field, we aim at discussing an interdisciplinary science related to anisotropies and fluctuations in astrophysics and cosmology. Gathering researchers from various backgrounds, we put together our tools and our knowledge on anisotropies and fluctuations. Various methods and theories have been developed in parallel but their use has often been restricted to one particular area. In particular, we will be sharing our experience on:

– theoretical predictions of anisotropy signatures, for given configurations of source populations and of the whole Universe;
– anisotropy analysis and measurement techniques;
– cross-correlation of data from various wavelengths and messengers, fluctuations in time.

In particular, the following themes will be discussed:

– cosmic microwave background: probing fluctuations of the content of the Universe through space and time;
– large-scale structure: galaxy distribution and probes of cosmology;
– warm hot intergalactic medium: soft x-rays tracers of the cosmic web, and the missing baryon problem;
– dark matter: gamma-rays as tracers of dark matter distribution and signature of annihilation;
– cosmic rays from low to ultrahigh energies: arrival directions and connections with magnetic fields.

Besides the 40-minutes invited talks, we plan to have 20-minutes contributed talks. We invite you to register to the workshop through our webpage (, where you will also find other details about the organisation of the event and accommodation. The number of participants will be limited to about 50. The deadline for registration is 15 August 2013, we will confirm your participation acceptance shortly after.

We hope to see you in Amsterdam during 25-27 September 2013.
