Please refer to the proposers web page for a description of the program, submission details, and schedule. We encourage prospective proposers to make particular note of the various joint/coordinated-observation programs we support spanning from radio to X-rays.
Cycle 21 offers joint observations with the Imaging X-ray Polarimetry Experiment (IXPE), and introduces the concept of Urgency 0, or "Immediate Urgency" Targets of Opportunity (TOOs).
