The TMR workshop on semi-analytical models of galaxy formation took place on 21/22 March 1997 at the MPA in Munich. In attendence were: Kelvin Wu (IoA, Cambridge) Carlos Frenk (University of Durham) Carlton Baugh Shaun Cole Philip Best (Leiden Observatory) Huub Rottgering Amina Helmi Rosaria Tantalo (Padova) Barbara Lanzoni (IAP, Paris) Guinevere Kauffmann (MPA, Munich) Simon White Houjun Mo Shude Mao Martin Haehnelt Adi Nusser Eiichi Egami (MPE, Munich) Claudia Maraston (ESO, Munich) Bodo Ziegler (Landessternwarte, Munich) Paula Belloni ------------------------PROGRAMME---------------------------------------------- FRIDAY, 21 MARCH (MORNING): 9:30 Guinevere Kauffmann - opening remarks, introduction to the Munich models 10:00 Houjun Mo - Analytic methods for estimating correlation funtions and higher order statistics 10:20 Shude Mao - Models of disk galaxy formation 10:45-11:15 COFFEE BREAK 11:15 Shaun Cole - Introduction to the Durham models 11:45 Carlton Baugh - Applications of the Durham models 12:15 Rosaria Tantalo - Chemical evolution and the Padova models 12:45-2:00 LUNCH FRIDAY, 21 MARCH (AFTERNOON): The participants divided into two groups. Group 1 consisted of modelling "experts" (Kauffmann, Cole, Baugh, Mo, Wu). Modelling techniques were discussed and compared in detail. Kelvin Wu described the new semi-analytic models being constructed in Cambridge in collaboration with Andy Fabian and Paul Nulsen. The Durham modellers described their updated code. It was decided that a comparison would be carried out between the Munich, Durham and Cambridge models. Future projects were outlined. Group 2 was led by Simon White and Carlos Frenk and was attended mainly by students and observers wishing to learn more about semi-analytic models and their capabilities. The format was an informal "question-and-answer" session. FRIDAY NIGHT: Workshop dinner held at Paulaner an der Au in Munich city centre. SATURDAY, 22 MARCH : The whole day was devoted to project discussions. The following topics were covered. 1) Chemical Evolution: the capabilities of the Padova models, the possibility of introducing the various ingedients of these models into the semi-analytic schemes to study the detailed enrichment history of our own Galaxy and others. 2) The Sizes of Disks: the Munich and Durham groups compared notes on their methods of predicting the evolution of the sizes of galaxies 3) Radio Galaxies: The Munich and Leiden groups discussed plans to model the evolution of the environments of radio galaxies. 4) Comparisons: A plan for comparing the models of different groups was set up.
