Emission and absorption line features are important diagnostics for the physics underlying extragalactic astronomy. The interpretation of observed signatures involves comparing against forward modeled spectra from galaxy formation simulations as well as more simplified geometries, while including the complex scattering radiative transfer (RT) of resonant emission lines. We introduce thor, a modern C++ radiative transfer code focused initially on resonant emission lines. thor is a high-performance, distributed memory MPI-parallel, multi-target code, running on CPUs, GPUs and other accelerators, yielding large $\sim 10-50\rm{x}$ speed-ups compared to previous CPU-only codes.
Active development scida scida is an open-source out-of-the-box python analysis tool for large astrophysical datasets, particularly cosmological and galaxy formation simulations using particles or unstructured meshes. This tool uses dask, allowing analysis to scale up from your personal computer to HPC resources and the cloud.
thor thor is a next-generation, massively parallel Monte Carlo radiative transfer code for astrophysical applications, running on all major CPU and GPU platforms by utilizing the C++ SYCL standard.
