Annual AGORA Workshops

In addition to online collaboration within smaller groups, Project-wide conferences are organized annually to keep ourselves and the Project as a whole on track.


We are delighted to announce that the 10th Workshop for the AGORA Project will be held 19-20 August 2022 at the University of California, Santa Cruz, at the heels of the annual Santa Cruz Galaxy Workshop.


Please fill out the registration form by June 15 if you wish to participate in the AGORA Workshop -- in-person or online.

In-person participation is encouraged for the Collaboration members who have been actively engaged in the ongoing projects and have been contacted by the Workshop organizers. Do talk to us if you are a student or a postdoc who is interested in helping the future AGORA analysis. Due to the ongoing COVID-19 situation, we may not be able to host too many in-person participants; however, if you cannot make it, participants are definitely welcomed to join us on Saturday 20 via remote connection.

Please feel free to forward this page to anyone potentially interested, especially to the young numerical astrophysicists who are looking for opportunities to participate in the science comparison in AGORA.

If any question, please do not hesitate to contact the AGORA Project Coordinator (Ji-hoon Kim).


● On Friday 19 the Workshop will be in the Simularium, Rm 180 of the Engineering 2 (E2) Building (map) in the northwest corner of the UCSC campus. This will be a joint session with the annual Santa Cruz Galaxy Workshop. On Saturday 20 the Workshop will move to Rm 221 of the Interdisciplinary Science Building (ISB; map).

● There will be a nominal registration fee to cover the breakfast, lunch, and dinner on Saturday 20 (note: different from the Santa Cruz Galaxy Workshop registration fee). You will pay this fee before or during the Workshop. [Read more]

If you are coming *only* for the AGORA portion of the week and not registering for the Galaxy Workshop, thus have no way of paying the registration fee, please inform the AGORA Poject coordinator.

For a detailed direction to the meeting venue and the parking nearby, please go to the "General Info" tab in the Santa Cruz Galaxy Workshop 2022 webpage. You may find it useful to visit the link for visitors by the Department of Astronomy and Astrophysics at UCSC.

Parking on campus is free on weekends. However, on weekdays you will need to display a parking permit which you can purchase during the Galaxy or AGORA Workshop registration. If you do not wish to purchase your permit through the Galaxy Workshop registration, please do so at the campus main entrance. If you plan to use public transportation the Santa Cruz Metro schedule to and from the UCSC campus might be helpful.

We recommend that if you plan to attend the Workshop, you arrange for lodging early. Although hotel policies vary, ask if there is a special rate for UCSC. You may find information about local lodging options in the "General Information" tab in the Santa Cruz Galaxy Workshop 2022 webpage.


● On Friday 19, the Santa Cruz Galaxy Workshop and the AGORA Workshop will hold joint sessions on high-resolution galaxy simulations. On Saturday 20 , we will have a live discussion on the ongoing and future projects in the Collaboration. To accommodate remote participants, we plan to broadcast the Saturday session via Zoom. Click to see the detailed program.

If you are joining us in-person, and wish to join any part of the Galaxy Workshop in-person, too, during the main week Aug. 15-19 and/or the preceding and following week Aug. 8-12 and 22-26, please talk to Avishai Dekel now.

The discussion agenda/meeting note is to be available in our latest Collaboration progress report (membership required). [Read more]

All simulation talks will be on Friday 19 during the joint session with the Galaxy Workshop. We do not plan to have any talks on Saturday. If you'd like to give your talk between Aug. 15-19 during the Santa Cruz Galaxy Workshop (joint sessions on Friday 19), talk to the Santa Cruz Galaxy Workshop 2022 organizers. If you are coming only to the AGORA portion of the week, but want to give your talk on Friday 19, please contact the AGORA Project coordinator.

What follows is a tentative program of the Workshop. Please also feel free to send any suggestion about the Workshop program to the Project Coordinator. Registered online participants will receive Zoom links for the Saturday discussion sessions.
