This is the 5th edition of the ChaICA series of meetings on computational astrophysics organised by IAU Commission B1: Computational Astrophysics. The meeting provides a forum especially for early-career researchers to present to their peers their work on computational algorithms, methods and new software projects. The talks can be a mix of both numerical methods and scientific results, but the focus of the meeting is on the computational and programming aspects. It is less formal than a scientific symposium, and so presentations on work-in-progress that does not yet have any scientific application/results are warmly welcomed.

• The meeting is open to everyone but (free) registration is required using a google form.
• All presentations will be broadcast live over zoom
• Presentations will be recorded if agreed by the speakers and made available to the community

Previous meetings of IAU Commission B1 in this series:

• ChaICA I 2019
• ChaICA II 2020
• ChaICA III 2021
• ChaICA IV 2022
