IAP/TMR meeting on "Population Synthesis and Galaxy Evolution" The meeting took place on Feb. 7-8 at the IAP and was attended by all local TMR members and the following participants from remote sites: Cambridge: A. Aragon-Salamanca, B. Poggianti Durham: C. Frenk, R. Sharples, C. Lacey Leiden: P. Best, L. Pentericci Munich: D. Thomas Padua: A. Bressan, M. Longhetti, Y. Ng The format of the meeting was that of short presentations (apart from a few exceptions!) interrupted and followed by lively discussions. The main themes of discussions were (see below for a more detailed program): Day 1: "The Star Formation History of Galaxies: Spectro-Photometric Diagnostics" Day 2: "The Infrared Emission from Galaxies" The main issues that came out of these dicussions, which were identified as most interesting collaboration projects near the end of the meeting, were: 1. The theoretical calibration and observational exploitation of direct star formation indicators (UV continuum, Ha line or OII line emission) to estimate reliably the evolution of the star formation density in the universe. 2. The combination of simple models of dust/IR emission of galaxies (as a function of gas and stars parameters) with models of galaxy formation to interpret the results of new IR surveys (e.g., ISO) 3. The calibration and use of photometric redshifts to tackle star formation in the universe at redshifts 1
