ALM Cycle 11 Proposal Submission Statistics

The ALMA Cycle 11 proposal submission statistics set some new records! Although the number of overall submitted proposals seems to be stabilising with 1712 proposals this semester, the number of hours requested on the 12-meter array continues to increase each cycle with over 30000 hours requested this cycle. The region with the highest number of proposals submitted was (again) Europe with a request of 11946 hours on the 12-m array, leading to the highest oversubscription of any region (over 8). East Asia and North America both had oversubscriptions of about 6.5, and Chile saw a big jump up in oversubscription which is now over 5. Band 6 remained the most popular this cycle, and Band 1 was requested by about 10% of proposals in its debut cycle.

The percentages of proposals for the 12-m array per region, science category, and requested receiver band for regular proposals are shown in the figure below.

42 large programs were submitted, of which four were awarded: two in the Circumstellar Disks, Exoplanets, and the Solar System category; and two in the Cosmology and High Redshift Universe category.

In Cycle 11, 60 proposals were submitted from the Netherlands. From these, 16 were accepted with an A, B or C rating. Worldwide, Netherlands-based astronomers were involved in 103 accepted proposals representing close to 2000 hours of ALMA time. This includes 16 researchers as PI and 106 individuals as co-I.
