Galactic Polarized EMission in PYthon
gpempy has been developed in the framework of the RADIOFOREGROUNDS project to reconstruct the large-scale magnetic field of the Milky Way through the observation and analysis of the diffuse polarized emission measured at submillimeter wavelengths by cosmic microwave brackground experiments.
Specifically, "gpempy" is a simulation software to create full-sky maps of thermal dust and synchrotron polarized emission from three-dimensional parametric models describing the Galactic Magnetic field and the density distribution of matter (relativistic electron and dust grain) at large scales.
gpempy is divided in four modules:
- BFIELD to estimate and visualize GMF models
- GalacticProfile to estimate and visualize models of matter density distribution
- GalacticForegrounds to estimate differential emission and produce full-sky maps of the integrated emission
- GalaxyBasics to handle space grid, coordinate transforms, etc.
gpempy is modular and can be used to visualize and access models in a user-friendly way.
More general information on gpempy can be read here and we present an overview, including practical examples, in the notebook.
