DESC Projects

This page lists Dark Energy Science Collaboration projects.

It is organized by working group or task force, and then by the status of the project. Projects associated with a topical team are currently listed under the working group hosting that team.

Click on a category to expand that group's projects, and then click a sub-category to expand further. Note that many projects are listed under multiple working groups.

You can get a link to any project by clicking on the link icon at the start of the row. This will keep working even if the project changes status.

The link in the "ID" column requires a DESC login to access.
