of the understanding of irradiation processes. The numerous new experimental developments in analysis of electronic emission (PES, PAD) now allow an ever improving detailed access to electron dynamics in irradiated species. In turn, a theoretical description of these highly involved dynamical scenarios calls for dedicated modeling. It is the aim of this paper to provide an overview of the theoretical description of observables from electron emission on the basis of the well established theoretical framework of Time-Dependent Density Functional Theory (TDDFT) [@Mar12]. This will be done with a view on applications, as far as possible in direct relation to ongoing experiments. Before going into the details, we will in this introductory section briefly remind the reader the typical systems (and associated scales) that we aim at describing. It is also of relevance to address here basic properties of laser pulses as presently accessible experimentally.

On the typical systems considered in this paper
-----------------------------------------------

In order to provide a basis for the forthcoming discussions, we shortly present here a few typical systems we shall consider in the following. This will be the occasion to remind typical scales associated to these systems, especially in terms of times and energies.
