Dear Astrophysics Strategic Technology & Research Accelerator (ASTRA) community members-

Thank you to everyone who participated in the Ad ASTRA Community Science Workshop in Pasadena, CA!. Over 450 people registered to attend the workshop, both in person and online. A group photo of the in-person participants can be found on the workshop webpage.

Special thanks to those who gave science and technology presentations as posters or talks, and to the moderators and panelists who managed the sessions and synthesized the material for late discussion.

Slides from all the talks can be found in PDF format on the workshop webpage; PDF versions of the posters are being added to the page as we receive them. If you presented a poster and haven’t yet supplied a PDF, please upload it to our Google Workspace folder, with a descriptive file name that includes your own name and the poster’s abstract number from the “Abstract Booklet: Poster Contributions”.

If you need a letter of attendance in the workshop, please contact Elise Furlan at furlan@ipac.caltech.edu. We anticipate that these will be available in early October.

The next steps in the ASTRA process are being overseen by the three Program Analysis Groups (PAGs): COPAG, ExoPAG, and PhysPAG, which are planning community meetings in the near future to discuss ASTRA concepts. The best way to keep up to date with these and other PAG activities is to join the respective mailing lists:

• COPAG instructions: select “Cosmic Origins News & Announcements”
• ExoPAG instructions
• PhysPAG page: select “Physics of the Cosmos News & Announcements”

Wishing you the best,
