There is an increasing evidence that small-scale phenomena occuring in the inner regions of galaxies are related to large-scale phenomena such as, e.g., merging or violent interactions between galaxies. Plausible scenarios (e.g. Rees, 1978) involve, for instance, accumulation of material from the outside along the accretion disk of a black hole and subsequent ejection in two opposite directions into the intergalactic medium. Active galaxies and QSO's may be the extreme examples of the link between large-scale phenomena contributing to the evolution of gala, xies. Moderately active or even normal galaxies are also submitted to entangled events on both scales. The aim of this communication is to illustrate the complementarity between high-resolution, small-field telescopes and Schmidt-type telescopes for the study of this phenomenology, and to stimulate further research by a few challenging examples.
