On behalf of the Joint ALMA Observatory and the partner organizations led by NAOJ in East Asia, ESO in Europe, and NRAO in North America, the ALMA Director, Sean Dougherty, is pleased to announce the ALMA Cycle 10 Call for Proposals for scientific observations to be scheduled from October 2023 to September 2024. 

Proposal submission opens at: Wednesday, 12 April 202315:00 UT
Proposal submission deadline is: Wednesday, 10 May 2023, 15:00 UT  

 

 

The Cycle 10 new capabilities are: 

  • Band 1 on the 12-m Array and for Stokes I only (no Stokes Q/U/V) is anticipated to be available from March 2024. 
  • Spectral scans that include Total Power observations. 
  • 4x4-bit spectral modes for improved sensitivity on the 12-m Array (dual polarization). 
  • Solar observations in full polarization in Band 3 using only the 12-m Array. 
  • Phased array mode in Bands 1, 3, 6, and 7 (the total time available for this mode will be limited to 50 hours). 
  • VLBI in Bands 1, 3, 6, and 7, including flexible tuning for spectral lines. 

 

New in Cycle 10 will be the availability of Joint Proposals with other facilities, including the Space Telescope Science Institute's James Webb Space Telescope, the National Radio Astronomy Observatory's Karl G. Jansky Very Large Array, and the European Southern Observatory's Very Large Telescope. 

Also, new this Cycle, Band-to-band phase calibration will be available for high-frequency observations on both the 7-m Array and all 12-m Array configurations. The total time available for projects needing band-to-band phase calibration will be limited.
