Modern challenges in stellar population synthesis.
THE PROPAGATION OF UNCERTAINTIES IN STELLAR POPULATION SYNTHESIS MODELING. I. THE RELEVANCE OF UNCERTAIN ASPECTS OF STELLAR EVOLUTION AND THE INITIAL MASS FUNCTION TO THE DERIVED PHYSICAL PROPERTIES OF GALAXIES Charlie Conroy 1, James E. Gunn, and Martin White2 1 Department of Astrophysical Sciences, Princeton University, Princeton, NJ 08544, USA.With stellar population synthesis one wants to determine as much information from the stellar populations of an unresolved galaxy from a single spectrum as possible. Having seen how complicated our Milky Way is, it is clear that one cannot retrieve all the information that one would like to have.Road safety patrol essays, bruzual charlot stellar population synthesis essay, free essays on american dream.

The isochrone synthesis method is introduced as a population synthesis method for galaxies. The method permits accurate distributions of stars in the theoretical color-magnitude diagram to be computed for any stellar population and thereby circumvent the problems faced by earlier techniques.A summary of the most significant results from the Isochrone Synthesis Spectral Evolution Models of Bruzual and Charlot (1992) concludes this presentation. Keywords Star Formation Stellar Population Star Formation Rate Elliptical Galaxy Initial Mass Function.
The stellar population synthesis models used were all at fixed solar metallicity to limit computing time, utilised the MILES stellar library and had age ranges from 6.5 Myr to 11 Gyr. Since we were not using this fit to extract stellar population metallicities and ages, considering only solar metallicity did not impact on our results and age-metallicity degeneracy effects were unimportant.
