Athena++ Workshop

Date & Time

Following the success of the 1st Athena++ Workshop in 2019, we are happy to announce the 2nd Athena++ Workshop to be held on May 8-12, 2023, hosted by the Center for Computational Astrophysics, Flatiron Institute. This workshop is built upon the vibrant scientific activities centered on the usage and development of the Athena++/AthenaK MHD codes for computational astrophysical fluid dynamics, and also serves as a celebration of Prof. Jim Stone’s career achievements at the age 60 milestone. The conference consists of three parts:

Part 1 (May 8): A series of review talks in celebration of Jim’s career achievements.
Part 2 (May 9-10): Athena++/AthenaK user meeting, on the science results obtained using the Athena++/AthenaK codes.
Part 3 (May 11-12): Athena++/AthenaK developer meeting, to discuss current and future effort in code developments.Meeting

Registered participants are welcome to participate in any of the three parts of the workshop, and we note that the developer meeting is generally more technical and primarily targets code developers. We also solicit speakers for contributed (15 minutes) talks for Part 2. Due to the limited space and tight meeting schedule, we cannot offer on-site poster presentations. Contributions not selected for an oral talk will be asked for presenting an e-poster online. The meeting format is hybrid. While we are open to online participation, we strongly encourage participants to attend the meeting in person, and especially require all the speakers to give their talks on site to facilitate interaction and discussions. The deadline for registration and abstract submission is March 31st, 2023 (US Eastern time). However, due to limited room capacity, the number of on-site participants is limited to 100 (and we will have to cut off the registration if this number is exceeded).
