SWIFTGalaxy is a module that extends SWIFTSimIO tailored to analyses of particles belonging to individual simulated galaxies. It inherits from and extends the functionality of the SWIFTDataset. It understands the content of halo catalogues (supported: Velociraptor, Caesar, SOAP) and therefore which particles belong to a galaxy or other group of particles, and its integrated properties. The particles occupy a coordinate frame that is enforced to be consistent, such that particles loaded on-the-fly will match e.g. rotations and translations of particles already in memory. Intuitive masking of particle datasets is also enabled. Finally, some utilities to make working in cylindrical and spherical coordinate systems more convenient are also provided.
Note
swiftgalaxy will be listed on the ASCL after the first publication using it. Citation details will then be given here. In the meantime, if you publish a paper using swiftgalaxy, please get in touch at submission time!
