Beginning in 2022, the ASST and ACO launched the “Athena X-ray Advances: ASST & ACO Science Webinars”. These science seminars are focused on the science case of Athena and are aimed at keeping the Athena community aware of exciting new science in areas relevant to Athena's capabilities. The entire series is in principle thought for members of the Athena community but, of course, it is open to the wider astronomy community.

Each webinar in the series is broadcast via Zoom Webinars. The time of the seminars to make a live connection for a broad community would typically be from 15:00 to 16:00 CEST/CET. The recorded seminars are archived on the ACO YouTube channel.

Detailed information about each seminar and the access details is shared with the Athena community members via e-mail and advertised in the Latest News menu and social media channels  (X (formerly Twitter), Facebook and LinkedIn).

Coming webinars will be shortly announced here.

Recorded webinars

They are publicly distributed in this dedicated playlist on the ACO YouTube channel.

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.
