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 31 March 2026, Nathalie Degenaar (University of Amsterdam) will present “Cosmic engines unleashed: winds and jets from accreting compact objects”

Abstract: Accretion onto compact objects powers some of the most energetic outflows in the Universe, producing fast, collimated jets and dense, slower-moving disc winds. These outflows can strongly influence the accretion process itself, the evolution of X-ray binaries, and their interaction with the surrounding interstellar medium. Despite their importance, the physical mechanisms that launch and regulate winds and jets remain poorly understood. In this talk, I will review the observed connections between accretion flow properties and outflow behaviour, and highlight recent, and in some cases surprising, discoveries of disc winds and jets. I will discuss how current observations are reshaping our picture of the accretion–ejection connection, and how Athena will play a key role in advancing this field.

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.
