Inhomogeneous reionization of the universe based on multi-dimensional radiative transfer calculations. 5. Formation and evolution of galaxies with focusing on UV background effects and supernova effects. 6. Observations of high redshift universe, which include the IR background 7.

FERRARA Summary & Overview of Collaborative Areas > A GENERAL DISCUSSION FOLLOWS PARALLEL GROUP DISCUSSIONS 10:30 The Seminar will now be split into a few parallel groups based on the Collaborative Areas individuated in the previous discussion. Participants can join one of the groups to which they feel they can contribute the most with the aim of setting up a joint collaboration. One of the members of such groups will report on the results of the discussion and possibly on the general l ines of the research project selected for collaboration. 12:30 ________ Lunch Break __________ PARALLEL GROUP REPORTS 16:30 The plenary session is resumed and a member of the groups will give a ~10 min summary of the discussion
