Aksenov, Alexei 
The hydrodynamic and the kinetic descriptions of electronpositron, proton plasma
We consider 1D sphericalsymmetrical nonstationary problem for the electronpositron and proton plasma in the wind or in the fireball. We base our approach on the numerical solution the kinetic Bolzmann equations for electron, positrons, protons and photons with the exact collisional integrals taking into account all binary and triple interactions. At the evolution of the GRB source the plasma passes different stages from optically thick to optically thin cases. In the first case the hydrodynamic approach can be applied, while the transparent plasma requires the kinetic approach for the description. We would like also to consider intermediate cases, then electronpositron can be considered in the frame of hydrodynamic, while and photons require the kinetic approach.

Large Scale Structure of the Universe 

Ferrari, Chiara 
Nonthermal component of galaxy clusters
I will review our current knowledge about the nonthermal component (relativistic particles and magnetic elds) of galaxy clusters, the largest gravitationally bound structures of the Universe. The cosmological and astrophysical implications of joint observational and theoretical studies of intracluster cosmic rays and magnetic elds will be detailed. I will also show the huge perspectives opened for this kind of studies by newgeneration instruments observing in the di erent band of the electromagnetic spectrum (radio, hard Xrays and Gammarays).

Stellar interferometry: a glance at basics
Nowadays interferometry and aperture synthesis are routinely used as tools to study the morphology of stars at High Angular Resolution. Though knowing the basics may appear as not mandatory for scientists using these observation techniques, they are somewhat required when analysing data and when conducting their interpretation in view of modeling the physical processes at work. Besides, on a general and cultural basis, it is useful for any scientist to know how these approaches are built and what are the fundamentals and what is the practice, both in ideal world and in real world. The sections of the lecture roughly are : scientific context and needs, fundamentals principles including a conceptual toolbox, functions of nterferometer, technical features and meaning of produced data.Then going from ideal world to real world the difficulties and remedies regarding exploitation of data are described in broad lines. Depending on available time nulling techniques, a peculiar use of interferometry, will be outlined.
