Objetivo

One of the most important questions in the study of galaxy evolution is the assumption that stars formed within star clusters with a preferred mass distribution (IMF) independent of time and environment. Major advances in understanding mainly the low-mass IMF variations have been made in the past decade, however, relatively a little attention has been paid to the high-mass IMF. As such some critical questions remain: Does the high-mass IMF vary as a function of time and environment? Is it appropriate to describe the high-mass IMF with a single power-law as we do now? The multi-wavelength datasets that are becoming available now can address these questions.

My proposal will tackle this fundamental and long-standing issue to the limit of our current observing and theoretical capabilities. Spatial multi-wavelength data from the latest generation of surveys combined with up-to-date modeling tools and state-of-the-art hydrodynamical experiments will be used to shed light into potential variations of the IMF and their effects on galaxy evolution. The goals of the proposal are: 1. Investigate the spatial distribution and connection between star formation events within galaxies; 2. Identify reliable multi-wavelength high-mass IMF diagnostics; 3. Investigate the effects of IMF variations in moderating galaxy evolution using simulations. The proposed project is both high-impact and timely. The high quality data products need for this project are now available thanks to the latest sky surveys (e.g. GAMA) and multi-wavelength experiments (e.g. ESA's flagship mission Herschel). The timely implementation of the project will constitute to one of the most complete studies of the high-mass IMF variations over an unparalleled wavelength span using statistically significant samples. My expertise in data analysis and modeling combined with the world-leading expertise of my host, Leiden Observatory, in the same field provides exactly the right background to carry out this project.
