Feature request by user astrotula ( http://galprop.stanford.edu/forum/viewtopic.php?f=13&t=146 ): Hi, Andrey! I've got some thoughts on the topic. In your post you mentioned that you are not sure how to implement a DM source computation into the online version of the GALPROP. I suppose the main difficulty here is to load annihilation yields - energy spectra at production of various annihilation products for various channels. In this context - do you know this website - http://www.marcocirelli.net/PPPC4DMID.html ? Essentially, the DM people there collected a lot of useful stuff including tabulated energy spetcra of annihilation products for different channels and WIMP masses. I'm thinking - what if you would try to use these tables for WebRun? A user will specify WIMP mass, channel, branching. Then some interpolation procedure for the table should be applied. And that's all regarding particle physics. Then to implement astrophysics - DM density distribution etc. - is relatively trivial. Thus, this can be a relatively easy way - just a potential idea... Maybe it's not a really general way - but at least for the first approximation. Because we can imagine that this opportunity - to get a DM source through WebRun - can be really popular for people...
