Mass inflow rates of between 1 and 1000 M theta yr-1 mean that line_3: this process has a considerable influence on the evolution, and possibly the line_4: formation of galaxies. Star formation must be particularly efficient and line_5: widespread. The driving force for these flows in the pressure of diffuse hot line_6: gas which is thermally unstable and leads to optical emission filaments. line_7: Further optical and UV studies of this process requires high resolution spatial line_8: and spectral observations. The ST FOC will match this need. line_10: Cooling flows have wide implications for dissipational galaxy formation, star line_11: formation, elliptical galaxy dynamics, the powering of active nuclei and the line_12: propagation of jets. FOC observations will provide the basis for understanding line_13: the distribution and IMF of large-scale and efficient star formation and line_14: continuing formation of large galaxies. ! ! end of abstract general_form_proposers: lname: FABIAN fname: A. mi: C. inst: CAMBRIDGE UNIVERSITY country: UNITED KINGDOM esa: X ! lname: MACCHETTO fname: F.
