NewAthena X-ray Advances: NASST and ACO Science Webinars

Beginning in 2022, the ASST and ACO launched the “Athena X-ray Advances: ASST & ACO Science Webinars”, which were reformulated in November 2023 as “NewAthena X-ray Advances: NASST & ACO Science Webinars.” These science seminars focus on the scientific case for NewAthena and aim to keep the NewAthena community informed about exciting developments relevant to Athena’s capabilities. The series is primarily intended for members of the NewAthena community but is open to the wider astronomy community.

Each webinar in the series is broadcast via Zoom Webinars. To facilitate live participation from a broad international audience, seminars are typically held from 15:00 to 16:00 CEST/CET. Recordings of the webinars are archived on the ACO YouTube channel.

Coming webinar

On 28 April at 15 CEST, Arne Rau (MPE) will present "The eROSITA Population of Tidal Disruption Events." 

Abstract: Tidal Disruption Events (TDE) are the observable signatures of a star being disrupted by intermediate or supermassive black holes. In my talk, I will present the results of the systematic search for TDEs in the German half of the eROSITA all-sky survey. Thanks to its unprecedented combination of sensitivity and all-sky coverage, eROSITA has enabled the first comprehensive study of the X-ray-selected TDE population. This work reveals remarkable diversity in their observational properties, particularly in their temporal evolution and their multi-wavelength behaviour. I will highlight the sample properties and implications for the luminosity function and rates (Grotova+2025). Furthermore, I will summarise key discoveries from selected sources, including recent findings of extreme variability on short and long time scales (e.g., Baldini+2025, Malyali+2026).

Code of conduct

All participants in the seminar series are expected to behave professionally and respectfully with other colleagues. Some basic guidelines are:

  • Behave professionally. Refrain from harassment in any form, avoiding offensive comments about individual characteristics, for example, age, gender, sexual orientation, disability, physical appearance, race, nationality or religion.
  • Ensure all communications are appropriate for a professional audience, taking into account the many different backgrounds of the participants. For example, sexual or sexist language and imagery are not appropriate.
  • Be respectful and do neither insult the participants or the facilitators of the webinars.
  • Critique ideas, not people.

Based on the code of conduct of XMM-Newton workshops.
