MC-Age — Estimating Stellar Population Ages with FSPS


This project uses FSPS, and python-FSPS to estimate the age of a stellar populations from a photometric SED. The code is available on github.

Science goal

We check local environment effects on SNIa by looking for correlations between Hubble Residual and the mass weighted average age of the local environment calculated from SDSS Scene Modeling Photometry. We also look at correlations between other variables including SALT2 stretch and color, and host galaxy stellar mass.

Indices and tables


  • This code assumes you are using SDSS ugriz SED’s. There are several lines of code that would need to be updated if this assumption is changed. Hopefully they are marked with comments.
