German eROSITA Consortium Unveils Groundbreaking X-ray Catalog from First All-Sky Survey
The German eROSITA consortium has publicly released the data from its participation in the inaugural all-sky survey conducted by the soft X-ray imaging telescope aboard the Spectrum-RG satellite. Known as the first eROSITA All-Sky Survey (eRASS1), this survey has produced an unparalleled X-ray catalog, comprising around 900,000 distinct sources. Published in the journal Astronomy & Astrophysics, the catalog showcases the outcomes of the initial six months of observations, during which eROSITA detected more sources than the entire 60-year history of X-ray astronomy. This release, accompanied by a series of scientific papers detailing discoveries, promises to revolutionize our understanding of the universe at high energies. The data, now accessible globally, encompasses diverse celestial objects, from supermassive black holes and X-ray-emitting stars to exotic phenomena, setting the stage for extensive research and exploration in the field of X-ray astronomy.
