The propagation of uncertainties in stellar population synthesis modeling I: The relevance of uncertain aspects of stellar evolution and the IMF to the derived physical properties of galaxies
Charlie Conroy, James E. Gunn, Martin White
The stellar masses, mean ages, metallicities, and star formation histories of galaxies are now commonly estimated via stellar population synthesis (SPS) techniques. SPS relies on s…
Non-linear structure formation and the acoustic scale
Hee-Jong Seo, Ethan R. Siegel, Daniel J. Eisenstein +1
We present high signal-to-noise measurements of the acoustic scale in the presence of nonlinear growth and redshift distortions using 320(Gpc/h)^3 of cosmological PM simulations. U…
Theoretical uncertainty in baryon oscillations
Daniel J. Eisenstein, Martin White
We discuss the systematic uncertainties in the recovery of dark energy properties from the use of baryon acoustic oscillations as a standard ruler. We demonstrate that while unknow…
