* Peer Review recommended Chandra X-Ray Observatory (CXO) Cycle 20 targets and proposals for observations to be carried out in a twelve-month period beginning about January 2019, including Guaranteed Time and Guest Observer proposals, Multicycle, Archive and Theory proposals, Large proposals, as well as Joint proposals with HST, NuSTAR, NOAO, NRAO, Swift and XMM-Newton. (Released Jul 10, 2018).

* NuSTAR Cycle 4 recommended category A, B, or C targets. Both Category A and B targets are guaranteed to be observed, but only Category A targets that are time-constrained are guaranteed to be observed in Cycle 4 (June 1, 2018 - May 31, 2019). The NuSTAR project expects to be able to observe approximately 50% of Category C targets. (Released Apr 19, 2018).
