The fourth Australian/eROSITA-DE Joint Collaboration Workshop will be held online from 25-27 March 2024.



The eROSITA (extended Roentgen Survey with an Imaging Telescope Array) instrument onboard Spectrum-Roentgen-Gamma satellite completed its first all-sky survey at X-ray wavelengths (eRASS1) in June 2020. The data obtained by eRASS1 already surpass those from previous all-sky X-ray surveys, having greater depth, image quality, and spectral coverage. At the end of 2021, the fourth (out of eight) survey of the full sky was completed. The combined data from the first four all-sky surveys are about 20 times deeper than the previous X-ray survey of the sky (ROSAT). 

The eROSITA data offer the opportunity to study extremely energetic events across vast scales in the Universe, from accreting binary systems at stellar scales to 10-million-degree shocks driven by galaxy cluster mergers. However, the full scientific exploitation of the eROSITA data requires a multi-wavelength approach.

With a strong suite of local wide-field radio and optical astronomy surveys and facilities, the Australian community is well-placed to link with our German eROSITA colleagues in order to make the most of exciting new opportunities for multi-wavelength astronomy projects across the southern sky.

For more information see the eROSITA webpage.


Workshop Purpose

This online workshop brings together the Australian and German eROSITA/eROSITA-DE communities to collaborate, discuss ongoing projects and foster ideas for new projects. We strongly encourage all interested to attend and consider submitting an abstract.

eROSITA-DE will release the first all-sky survey on 31 January 2024. For those unfamiliar with the AAL/eROSITA-DE collaboration, this workshop is an excellent opportunity to learn about the data and brainstorm new projects that combine Australian data with the deeper still proprietary eROSITA data. 

The workshop will include a variety of presentations and opportunities for discussions and networking.

Workshop Structure

In 2024, we have expanded to 3 days x 2.5 hours/day to allow all talks to be presented during the workshop but ensure there is still time for discussion. In order to allow synchronous participation by both Australian and German parties, the workshop will be run between 7:00pm and 9:30pm AEDT (9:00am and 11:30am CET) on 25-27 March 2024.

Each day will start with one longer, foundational presentation before moving into submitted presentations. Each submitted talk has been allocated ten minutes speaker time and presenters are kindly requested to ensure their presentation keeps to time. Extra time for discussion has been arranged as part of the program.

Presentation recordings will be made available after the workshop on the eROSITA page of the Astronomy Australia website.



The workshop will take place in a dedicated space in Gather. Links to access the Gather Auditorium will be circulated to registered attendees by 22 March 2024.
