We are pleased to invite you to the Astrophysics Working Group Meeting. This meeting will be conducted in a hybrid format, allowing for both in-person and virtual participation. The in-person sessions will be hosted by the Max Planck Institute for Astrophysics (MPA) in Garching, Germany. Additional details, such as the meeting schedule, travel and online meeting information, are available on this website.

There is no registration fee. The institute generously provides access to its facilities and staff support without charge. However, participants are responsible for their own meals, accommodations, and travel expenses. If financial constraints are a concern, please mention this in the comment section at the end of the registration form.

Registration has been closed. Unfortunately, we cannot admit more participants as we have reached our capacity.
