After the first 1.5 years of operations, the Einstein Probe mission, led by the Chinese Academy of Sciences in collaboration with the European Space Agency (ESA), the Max Planck Institute for Extraterrestrial Physics, Germany, and the Centre National d'Études Spatiales (CNES), France, has publicly released the first batch of science data, for which the proprietary period has expired.
This data release encompasses Level 1 to Level 3 science data products from the Follow-up X-ray Telescope (FXT), collected after the commencement of science operations on 11 July 2024. There are two data centers in China operating archive interfaces, the National Astronomical Data Centre (NADC) and the National Space Science Data Centre (NSSDC). ESA has opened the Einstein Probe Science Archive (EPSA) containing public, calibrated high-level data, i.e., calibrated data covering level 2 (events files) and level 3 (images, spectra, light curves).
The dataset includes 1,615 Observation IDs and is of significant scientific value for in-depth studies of stars, galaxies, active galactic nuclei, clusters of galaxies, supernovae and supernova remnants, gamma-ray bursts, as well as mergers of compact objects such as black holes and neutron stars, shedding light on extreme physical processes in the universe.
As the first mission to publicly release its data via ESA’s Astronomy Multi-Mission Archive, EP has been hailed by the agency for revolutionizing transient science.
