Dusty SAGE

Dusty SAGE is a semi-analytic model for galaxy formation that include a detailed prescription for dust evolution. This model is a modification of Semi-Analytic Galaxy Evolution (SAGE) described Croton et al. (2016). The description of Dusty SAGE is given in Triani et al. (2020).

Dusty SAGE runs on any N-body simulation whose trees are organised in a supported format and contain a minimum set of basic halo properties. For testing purposes, treefiles for the mini-Millennium Simulation are available here.

Installation

SAGE requires only GSL and should compile mostly out of the box.

Downloading

$ git clone github.com/dptriani/dusty-sage

Building

$ cd dusty-sage
$ make

Running

To run Dusty SAGE, you need to specify the parameters needed by the model in the parameter file (.par). An example of a parameter file is given here. To run the model:

$ ./sage <path to .par file>
