Spectrum-Roentgen-Gamma (SRG)

The scientific spacecraft "Spectrum-Roentgen-Gamma" (Spectr-RG or SRG) is an X-ray observatory. SRG's main scientific goal is to chart an unprecedented map of the Universe in X-rays on which all large clusters of galaxies will be marked. The scientific payload consists of two independent telescopes:
  • eROSITA, a soft-X-ray survey instrument, being provided by Germany
  • ART-XC (Astronomical Roentgen Telescope- X-ray Concentrator), a medium-X-ray-energy survey instrument, being developed by Russia.
The HEASARC currently serves part of the eROSITA data archive.

The ART-XC archive will be available in the near-future (~2025).

19 Sep 2024 - eROSITA sky-survey data now available at HEASARC: First eROSITA sky-survey data release data (eRASS1) is now available at HEASARC!

31 Jan 2024 - First eROSITA sky-survey data release: The German eROSITA consortium released the data for its share of the first all-sky survey by the eROSITA telescope on the Spectrum-RG (SRG) satellite. With about 900,000 distinct sources, the first eROSITA All-Sky Survey (eRASS1) has yielded the largest X-ray catalogue ever published. Along with the data, the consortium released a series of scientific papers. See the press release for more information.

10 Jun 2020 - SRG completes first all-sky X-ray survey: SRG completes first all-sky X-ray survey, which lasted from December 8, 2019 to June 10, 2020

15 Dec 2019 - eROSITA completes CAL-PV Phase: eROSITA completes the Calibration and Performance Verification (Cal-PV) program

22 Oct 2019 - eROSITA First Light: On 22 October 2019, the beautiful first X-ray images of the eROSITA telescope were presented to the public at the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching. After an extended commissioning phase, since October 13 all seven X-ray telescope modules with their custom-designed CCD cameras have been observing the sky simultaneously. The first combined X-ray images of our neighbouring galaxy, the Large Magellanic Cloud, and a pair of interacting clusters of galaxies at a distance of about 800 Million lightyears, show remarkable details and demonstrate the promise of the ambitious science programme planned with the space-borne telescope.

14 Jul 2019 - The Launch of SRG: At 14:31 on 13 July 2019, the Spektrum-Roentgen-Gamma (SRG) space mission successfully lifted off from the Baikonur cosmodrome, carrying aloft the eROSITA and ART-XC telescopes.
