"eROSITA Unveils Largest X-ray Sky Survey Catalog with 900,000 High-Energy Cosmic Sources"

The German eROSITA consortium has released the largest X-ray catalog ever published, containing about 900,000 distinct sources from the first eROSITA All-Sky Survey (eRASS1). The data, which includes scientific papers describing new results, will revolutionize our knowledge of the universe at high energies. The catalog covers half the X-ray sky and includes supermassive black holes, X-ray-emitting stars, clusters of galaxies, and other exotic sources. The release also provides images of the X-ray sky, individual photon lists, and software for data analysis, with cosmology results expected in approximately two weeks.
