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.

Speaker: Dr Anna Ogorzałek (NASA GSFC & University of Maryland)

Title: Mapping the hidden drivers of galaxy evolution

Abstract: What are the drivers of galaxy evolution?” remains a central question of modern-day astrophysics. A key recent advance is the recognition that galaxies live in large gaseous halos filled with the Circumgalactic Medium (CGM), which might be the missing piece of the galaxy evolution puzzle. However, quantifying the impact of the CGM on galaxies remains challenging because it is composed of extremely dilute, low-brightness gas. Furthermore, because the dominant phase of this gas is often hot in normal galaxies (∼10^6 K), the soft X-ray band is critical for determining its impact on the growth of galaxies. In this talk, I will give an overview of our progress in understanding the hot CGM using current X-ray instruments. I will then demonstrate why spatially resolved, high-spectral-resolution observations with future instruments like NewAthena’s XIFU are absolutely critical to solving the mysteries of the CGM and determining the ultimate fate of galaxies.

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.
