ALMA Cycle 13 proposal preparation and important dates

/in , , /by

The Cycle 13 call for proposals is here! The proposal deadline will be 23 April 2026. Be aware that there is a brand-new web-based ALMA Observing Tool for submitting proposals this cycle. Please start early!

Allegro is happy to help with questions regarding:

  • Dual anonymous review process.
  • Distributed peer review.
  • Accessing the ALMA archive.
  • Using the ALMA Observing Tool (OT) to prepare your observing program.
  • Technical setup of proposals.
  • New features in Cycle 12.
  • Anything else related to your proposal preparation!

For quick questions, we encourage our community to reach out to us via email (alma@strw.leidenuniv.nl). Leiden members are also highly encouraged to interact with us via the Allegro Slack channel (#allegro) in the Leiden Observatory internal Slack; we will keep an eye out for messages! Mutual discussions with colleagues and experienced ALMA users in our community will add value to this exchange and are welcome and appreciated.

For more complicated cases or hands-on help with the OT, we offer face-to-face support (both in-person and Zoom options are available). Our office is BW 4.34 in the Gorlaeus Building of Leiden University, and you can contact alma@strw.leidenuniv.nl for a Zoom link.

For first-time proposers and complicated programs, we recommend coming by as soon as possible to discuss getting started and feasibility.

Finally, we invite everyone to a celebratory borrel after the proposal deadline on April 23. All are welcome whether you submitted zero or ten proposals!
