N2 - One of the major challenges in modern astrophysics is the study of how galaxies have formed and evolved over the past Hubble time. Observationally, ever larger surveys are or will be carried out to widen our horizon by studying increasingly faint and more distant objects in greater number and tremendous detail. Complementary, studies of nearby star clusters can reveal the state of their host galaxy during cluster formation. Adequate models to extract the physical quantities of the studied objects in a reliable, accurate and physically sound way are needed to exploit these observations. Our GALEV evolutionary synthesis models offer an excellent answer to fulfill this urgent demand.
But what makes them special? Different compared to other evolutionary synthesis models?
- they follow the chemical evolution of galaxies properly
- they contain nebular emission lines, which dominate the spectra of young clusters and actively star-forming galaxies
- they provide photometric models in a huge number of filters (currently more than 200, including all HST filters [also for the new WFC3], filters from all major ESO observatories, and filters of large public surveys, such as SDSS and 2MASS)
- for star clusters, they include the effects of cluster dissolution (found to affect age and mass determinations by a factor of a few)
- Build your own galaxy at www.galev.org! It's fun .... and free!
And they are about to become even better!
- with high-spectral resolution spectra
- and with isochrones incorporating the effects of interacting binary stars
I will review the advantages of our models, and present our current work to provide YOU with the best possible models.
