Codes

Here, you’ll find publicly available simulation software. These contain both radiative transfer codes (i.e. Powderday and Turtlebeach), as well as the results from large simulation campaigns that may be useful (i.e. template SEDs and SLEDs). Click on the corresponding tab for each code for more information.

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 bundles fps (and its python hooks, python-fsps) for stellar SEDs, Hyperion for dust radiative transfer, and yt to produce realistic SEDs and images for galaxy formation simulations.

The eventual goal is to have the code work for most publicly available galaxy evolution codes.  Right now it works for derivatives of Gadget (including Gizmo), is in Beta for Gasoline/Changa, and the RAMSES front ends are under development.   While a formal release is planned for Summer of 2015, please feel free to fork/use at:

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.

DOG SEDs

dogsReference: Narayanan, Dey et al. 2010 MNRAS 407, 1701
Code: To come soon (being migrated over from Arizona Server)
In the mean time, please find them at the old server:  http://ajax.as.arizona.edu/~desika/DOGtemplate/Site/DOG_SED_Templates.html

Purpose: To calculate the theoretical SED Templates for 24 micron selected Dust Obscured Galaxies as a function of luminosity
