First eROSITA sky-survey data release makes public the largest ever catalog of high-energy cosmic sources

The German eROSITA consortium has released the data for its share of the first all-sky survey by the soft X-ray imaging telescope flying aboard the Spectrum-RG (SRG) satellite. With about 900,000 distinct sources, the first eROSITA All-Sky Survey (eRASS1) has yielded the largest X-ray catalog ever published. The work is published in the journal Astronomy & Astrophysics.
