Welcome to Powderday’s documentation!

powderday is a dust radiative transfer package designed to interface with galaxy formation simulations in order to produce realistic spectral energy distributions and images. The code utilizes`fsps <https://code.google.com/p/fsps/source/checkout>`_ (and its python hooks, python-fsps) for stellar SEDs, and Hyperion for dust radiative transfer. Threaded throughout is yt.

The code has two principle aims - to be flexible (and extremely modular), and to be easy to use. The package is written in python, though makes use of fortran, C and cython.

As of now, the code works principally for Gadget, Gizmo and other variants. Support for Gasoline, RAMSES, ART and Enzo are planned however. The current timeline is for TIPSY front ends to be built over Spring 2015, with AMR support to follow

Finally, this code benefits from the contributions, either directly to this software, or indirectly by contributions to dependency software, by many astrophysicists, including Matt Turk, Tom Robitaille, Robert Thompson, Charlie Conroy, Dan Forman-Mackey and Phil Hopkins.
