A: GALPROP is a code that solves the cosmic ray propagation equation
with user-defined parameters, and calculates diffuse galactic emission
produced by cosmic rays.
See section Theory for more details.
Algorithms, data and physical models used in GALPROP are also discussed in our
publications and the GALPROP Manual.
Q: How can I use GALPROP?
A: Via a free service available on this web site, GALPROP WebRun.
After a simple registration procedure, you will gain access to
a web page that allows you to set up the parameters of a cosmic ray
propagation model and run a GALPROP calculation on a computing cluster
at Stanford University with a click of a button.
Q: Can I get the source code?
A: Yes. To obtain the source code, register at the GALPROP web site and
navigate to the code download page.
Q: Why use the WebRun service instead of downloading the code?
A: Using the web-based service is the easier and more reliable way to use GALPROP. To use
GALPROP via WebRun, you do not have to install the code and all the libraries it depends on locally
on your computer. The configuration you create in WebRun will be automatically checked
for sanity using rules written by the GALPROP team. By using WebRun, you will also
have our high performance computing cluster at your disposal, and you will be
able to easily share and publish your results.
Q: What is new in GALPROP version 56?
A: Compared to version 54 there have been numerous improvements, including significant speed
improvements that now enable full 3D calculations in just a bit more time than the older 2D calculations.
There are new 3D ISM (gas, ISRF, GMF) models, and many features including specifying an arbitrary viewing
location for interstellar emission calculations (GALPROP v56 can be used for modelling cosmic rays and interstellar emissions from externally viewed galaxies). See the Appendix in Porter et al. ApJ 846, 67 (2017) for additional information.
Q: What is new in GALPROP version 54?
A: It uses the most recent data on gas distribution and interstellar radiation field,
many bugs have been fixed, and a number of numerical procedures improved. It is also
much faster thanks to using parallel processing.
Q: How can I use GALPROP results in my publications?
Q: How can I improve GALPROP, request a feature or report a bug?
A: Use Bugzilla to report bugs and the Forum
to discuss GALPROP or request features. If you want to propose integrating your
physical model with GALPROP, please contact us.
