Call for Proposals
The ALMA Director, on behalf of the Joint ALMA Observatory (JAO) and the partner organizations in East Asia, Europe, and North America, is pleased to announce the ALMA Cycle 4 Call for Proposals (CfP) for scientific observations to be scheduled from October 2016 to September 2017. It is anticipated that up to 3000 hours of the 12-m Array and up to 1800 hours of the Atacama Compact Array (ACA), also known as the Morita Array, will be available for successful proposals from Principal Investigators (PIs) in Cycle 4. Proposals must be prepared and submitted using the ALMA Observing Tool (OT), which is available for download from the ALMA Science Portal (www.almascience.org). Proposals will be assessed by competitive peer review by a single international review committee.
ALMA Cycle 4 proposal submission will open at:
The ALMA Cycle 4 proposal submission deadline is:
Table 1 summarizes these and other important milestones for Cycle 4.
ALMA provides continuum and spectral line capabilities for wavelengths from 0.32 mm to 3.6 mm, and for angular resolutions from 0.024” to 3.7” on the 12-m Array. Cycle 4 offers several new technical capabilities, including Solar, millimeter-wavelength Very Long Baseline Interferometry (mm VLBI), spectral-line linear polarization, and ACA stand-alone observations. In addition, for the first time ALMA will accept Large Proposals, which are programs that request more than 50 hours of time on the 12-m Array or the ACA in stand-alone mode to address key scientific questions. Up to 15% of the available time will be allocated to Large Proposals.
The Proposer’s Guide provides all the necessary information needed for submitting proposals including an overview of the types of proposals offered in Cycle 4 (Section. 4), information on planning (Section. 5) and submitting (Section. 6) proposals, and an overview of technical capabilities (Appendix A). Investigators are also strongly encouraged to review the ALMA User's Policies which describe the long term core policies used by ALMA and describes the policies for proposal change requests and the requirements for the use of ALMA data. Questions about proposal preparation and submission, data use or general ALMA policies should be submitted through the ALMA Helpdesk).
