Information about ALMA for Chilean Astronomers

Chilean astronomers have access to the Atacama Large Millimeter Array (ALMA) through agreements between the Astronomy Department of the Universidad de Chile (DAS) or ANID/CONICYT and the individual ALMA partners: NRAO, ESO, and NAOJ. The DAS and ANID/CONICYT are formally responsible for administering this share of time, and have agreed to participate in the international ALMA Call for Proposals, including a panel and distributed review, to take advantage of the organizational effort and worldwide expertise of the review process. As such, Chilean astronomers wishing to propose for ALMA time will need to propose through the regular ALMA proposal cycle.

The latest information regarding proposing for ALMA can be found here:

ALMA Eligibility Requirements to Qualify for Chilean Partner Time

Only sponsors of visitors, students, and postdocs should submit the CRC form.

All proposals are evaluated on the basis of scientific merit by a distributed peer review system or by a panel-based proposal review system. Submitted proposals will qualify for Chilean eligibility status based on the following requirements:

1.- The PI must be affiliated with a Chilean Institution and reside in Chile. Residency will be determined following the rules laid out by Sociedad Chilena de Astronomia (SOCHIAS) and specifically by comparing the list of proposers against the "Lista de Acceso a Tiempo Chileno (LATC)" maintained by SOCHIAS. Proposers must ensure that their department head puts them on this list before the Cycle 13 proposal deadline.

2.- Each proposal must have at least one permanent Chilean faculty member among the proposers (PI or co-I). This faculty member will act as sponsor and ultimately may be responsible for reporting progress on accepted programs if the PI does not submit a proposal in future cycles (including this one) or leaves Chile. Support confirmation is required via the CRC form.

3.- Student-led proposals require a support confirmation from faculty supervisor via the CRC form. The student should be included in the SOCHIAS LATC.

ALMA has indicated that proposals that are submitted through Chilean time and, based on reasons related to the rules above, are found not to be compliant will not be further considered in the Review Process and will not be eligible for the International Time.

Only sponsors of visitors, students, and postdocs should submit the CRC form. All supporting information (CRC form) must be submitted by Wednesday, April 29, 2026 at 6pm CLT to alma_crc@das.uchile.cl. If questions remain after reading the above and compiling the form, these can be directed to alma_crc@das.uchile.cl

CRC FORM: For Cycle 13, the CRC submission will occur via this LaTeX form.

It should be noted that for ALMA Cycle-13, the review process will be under the dual anonymous scheme. To not affect the anonymity of the review process, the Chilean proposal eligibility (see above) of a given proposal will be checked by a Chilean representative(s) who does not participate in its review process.

Important Deadlines for 2026 :

- April 23, 2026: Cycle 13 Proposal Deadline
- October 2026: Start of ALMA Cycle 13 observations.
- September 2027: End of ALMA Cycle 13 observations.
