AAL 2023/24 Annual Report – eROSITA

eROSITA (extended Roentgen Survey with an Imaging Telescope Array) is an X-ray instrument that has conducted multiple all-sky surveys. eROSITA has been in safe mode since February 2022, however the partnership between AAL and the German eROSITA Consortium (eROSITA_DE) has consistently provided exciting new opportunities for multi-wavelength astronomy projects across the southern sky.

AAL is proud to support Australian-based astronomers and institutions via the agreement that made this collaboration possible, signed between AAL and the German eROSITA Consortium (eROSITA_DE). Find out more about the collaboration here.

Project highlights

Release of the eROSITA All-Sky Survey (eRASS1)

Data from the first all-sky survey by eROSITA was released in January 2024, yielding the largest X-ray catalogue ever published. A series of scientific papers were also released along with the data, including two led by Australian researchers Dr Adelle Goodwin and PhD student Silvia Mantovanini from International Centre for Radio Astronomy Research (ICRAR), Curtin University. Lead investigators Dr Goodwin and Mantovanini combined the X-ray data from eROSITA with optical and radio data from Australian surveys to get deeper insights into high energy cosmic phenomena.

Dr Goodwin watched a supermassive black hole destroy a star, located at the center of a galaxy 1.3 billion light years away. The team of researchers managed to track the stars' debris, ejected by the black hole over 2 years as it moved through the galaxy. Image credit: DESY, Science Communication Lab.

eROSITA Collaboration Workshop

The fourth Australian/eROSITA-DE Joint Collaboration Workshop was held between 25-27 March 2024 for 70 Australian and German astronomers involved with eROSITA projects. The workshop took place in the online environment Gather Town which supports informal networking in addition to scheduled workshop talks. 18 talks were delivered over 7 sessions, and participants connected further during informal networking sessions.
