“a University of Virginia professor is mapping it in 3D, using 46 million galaxies and quasars and 19 million stars”

CORROBORATED

Multiple web sources confirm the creation of the largest 3D map of the universe using DESI. While one source mentions 47 million galaxies and quasars (close to the 46 million claimed), the general fact of the mapping project and the scale are corroborated across multiple reports.
