abstract = {<p style="text-align: justify;">In this paper, we introduce a moment closure which is intended to provide
a macroscopic approximation of the evolution of a particle distribution function, solution
of a kinetic equation. This closure is of non-local type in the sense that it involves
convolution or pseudo-differential operators. We show it is consistent with the diffusion
limit and we propose numerical approximations to treat the non-local terms. We
illustrate how this approach can be incorporated in complex models involving a coupling
with hydrodynamic equations, by treating examples arising in radiative transfer.
We pay a specific attention to the conservation of the total energy by the numerical
scheme.</p>},
