The pyreact wrapper allows the C++ code (the native language of ReACT) to be called by Python code. Alternatively, there is a Docker extension in VS-code where you can (re-)start your container and see the files there all at ones, which makes the navigation easier. charming_faraday: mybuild RUNNING PORT:8888) -> open the command line (CLI-option in the Docker app when you hover over a container). You can later come back to your image in the individual container by opening the Docker app -> going to Containers, where you will see a list of all your containers -> choose and run a container with the 'mybuild'-image you used before (e.g. One should also make sure that sundials is on your library path, for example Get these packages using your package manager of choice (e.g., homebrew on mac OS).

SUNDIALSįor Spherical Collapse module ( reactions/src/SCOL.cpp) you will also need the SUNDIALS package version 4.1.0 (also tested to work with version 5.0) Note that later versions of sundials may produce errors as they update their functions so please work with version 4.1.0. You will need to have a version of gsl installed (gsl 2. The ReACT extension makes use of a number of gsl packages such as odeiv2 package which is part of the gsl library.

ReACT is written in C++, so you'll need a modern C++ compiler. Real space bispectrum at 1-loop level** (1808.01120): reactions/src/BSPT.cpp.Įxact perturbation theory kernels up to 4th order** (1808.01120): reactions/src/BSPTN.cpp.īeyond LCDM modifications to background, linear, 2nd, 3rd order Poisson equation and fully nonlinear Poisson equation: reactions/src/BeyondLCDM.cpp. Numerical perturbation theory kernels up to 3rd order (1606.02168): reactions/src/SpericalFunctions.cpp. Real and redshift space LSS 2 point statistics (1606.02520): reactions/src/SPT.cpp. Halo model power spectrum (1812.05594): reactions/src/HALO.cpp. Spherical collapse (1812.05594): reactions/src/SCOL.cpp. ReACT can perform the follwing calculations for general theories beyond LCDM notebooks : example python notebooks for ReACT computations plus two Mathematica notebooks performing translations between covariant theories and modifications to the perturbative Poisson equation and comparisons of different parametrisations of the nonlinear Poisson equation.cosmosis : contains the cosmosis module for ReACT.pyreact : contains the wrapper functions calling the c++ code from python.Specifically, these can be found in reactions/src. reactions : contains all the c++ source code for the calculations.It allows the efficient computation of many large scale structure observables for a wide class of gravity and dark energy models.

ReACT is a halo model and standard perturbation theory code based on the software packages Copter (0905.0479) and MG-Copter (1606.02520). ReACT v2: ACT-io et ReACT-io This repository contains version 2 of the ReACT code.
