If you have ordered a parking permit during registration, it should be picked up at the UCSC entrance kiosk between 8am and 4pm (Monday-Friday). Please make sure you get your permit from this kiosk as you enter campus, as they will not be available at the upper campus (where the workshop itself takes place).

Covid Testing

If you are traveling internationally and you need a Covid test for your return, or would like a covid test for any other reason, you can find information about testing sites and test options at:

Housing and Transportation


No housing will be available on campus this summer. We recommend that if you plan to attend the conference, you arrange for lodging early. Although hotel policies vary, at the time you make your reservations you should ask if there is a UCSC rate.

Airport shuttles
Shuttle services from the airport to campus or to your lodging are available for a fee:

Public transport
Public transportation options to, from, and around Santa Cruz can be done through the Santa Cruz Metro.

Local Lodging Options

Although hotel policies vary, at the time you make your reservations you should ask if there is a discounted UCSC rate.

If you will be staying an additional week for collaboration, either before or after the workshop, you may want to try the following suggestions for a bit longer term and possibly less expensive housing:

  • Craigslist - Shows housing for rent in many areas

In addition we have a listing from Academic HR, which contains many housing options for extended stays, typically in faculty/UCSC employee houses. This list is available upon request.

We thank the UCSC Foundation Board Opportunity Fund for supporting the 2023 Santa Cruz Galaxy Workshop and the AGORA Workshop.

The Santa Cruz Galaxy Workshop (SCGW) also acknowledges help from the Astronomy and Astrophysics Department, the Physics Department, the Environmental Studies Department, University of California Observatories (UCO, headquartered at UCSC), the Santa Cruz Institute for Particle Physics (SCIPP), the Center for Information Technology Research in the Interest of Society (CITRIS), and the UCSC Engineering School. SCIPP provides valuable staff support for the SCGW and AGORA workshop; CITRIS, Engineering, Environmental Studies, SCIPP and UCO provide the meeting rooms; and the Astronomy and Physics Departments and SCIPP provide office space and internet connections for participating astronomers.

AGORA receives extensive computer support from the US Department of Energy's National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory, where the outputs from all the AGORA galaxy simulations are stored and analyzed. The AGORA galaxy simulations are carried out by eight teams of astrophysicists from universities and research institutes around the world. The public AGORA galaxy simulation outputs are hosted at the FlatHUB (https://flathub.flatironinstitute.org/).
