There are significant changes in the Chandra Peer Review Process starting with Cycle 27. For the first time, proposals will be subject to a distributed peer review process, wherein each proposing team will identify a team member as the designated reviewer responsible for the review process. The results of the distributed review will be used to inform the selection of most proposals, while Target of Opportunity (TOO), Large Program (LP), and Very Large Program (VLP) proposals will also undergo a panel review that will make final recommendations. Further details can be found in Section 9 of the CfP.
Proposals for Archival Research and Theory/Modeling proposals are not a part of this CfP. Once funding for such programs is available, the CXC will issue a separate CfP.
