EzGal

Web Interface

To quickly download models the web interface can be accessed here:

If you need to specify alternate formation redshifts or a different cosmology, use the model server. It will calculate models and email them to you.

About

EzGal is a tool that takes models of how the SED of a stellar population evolves with time and projects it through filters to calculate magnitude evolution and mass-to-light ratios as a function of redshift. For those familiar with the Bruzual and Charlot (2003) model set, this performs the same function as the program cm_evolution which is distributed with their models. EzGal can read in Bruzual and Charlot binary ised files as well as plain text files, allowing it to work with any model set. You can use it is a strictly command line utility to output text files for later use, or you can call it from python as a module to generate models on the fly. It can store the seds and evolution models in fits files for quick retrieval later. A convenient way to use it is to generate evolution models on a grid of formation redshifts for many filters, store all the calculated models in a single fits file, and then just use that fits file (in conjunction with EzGal) to quickly fetch redshift evolution models for all your gridded formation redshifts and filters. All this takes just a few lines of code.

I have already integrated a number of different models from 5 common model sets (Bruzual and Charlot 2003, Charlot and Bruzual 2007, Maraton 2005, Percival et al. 2009, and Conroy, Gunn, and White 2009) into EzGal. EzGal also has a web interface which can be used to easily extract magnitude and mass-to-light evolution from these models and for our filter set.

Download

Download EzGal here: http://www.mancone.net/tars/ezgal.tar.gz.

Just unzip it and place it in your python path or working directory to get started. All the model files used on the web interface are also available for download. These will let you get going with EzGal quickly because they contain a wide variety of models with varying model sets, IMFs, and SFHs, all ready to be used with EzGal. Go to the download page to get them. You can also view the EzGal manual here
