Click to download HDF5 fileThis page serves as a centralized platform for accessing the ray-tracing maps and catalogs generated by Konietzka et al. in 2025 (arXiv:2507.07090).
The two circular images above illustrate a full-sky dispersion measure map observed within a Milky Way–like environment.
A video showing the evolution of this full-sky map is available here.
Below, you will find links to download the data underlying this map, as well as additional catalogs.
Each catalog consists of a dispersion measure (DM) dataset of dimension Nrays x Nredshifts entitled DMvalues.
Nrays is the number of rays provided. Nredshifts is the number of redshift bins.
The redshift values corresponding to the redshift bins can be found in the table entitled redshifts.
If you use these data, we ask you to cite Konietzka et al., 2025 (arXiv:2507.07090).
A Jupyter notebook explaining how to load and plot the data can be downloaded here: Jupyter Notebook
