High Energy Astrophysics Approved Guest Observer/Investigator Programs & Targets


Recent High-Energy Astrophysics AOs/NRAs for which Lists of Accepted Targets/Proposals are Now Available (listed in reverse chronological order of release)

* Recommended INTEGRAL AO-15 General Program of Observations to be carried out in the 12-month period starting around Jan 1, 2018. (Released Jun 8, 2017).

* Selected Stage-I Fermi Cycle 10 Guest Investigator Program proposals (Released May 31, 2017).

* NuSTAR Cycle 3 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 3 (June 1, 2017 - May 31, 2018). The NuSTAR project expects to be able to observe approximately 50% of Category C targets. (Released May 10, 2017).

* Swift Cycle 13 recommended proposals, including both proposals for funding only and observing proposals, and targets; accepted Cycle 13 ToO proposals may be triggered until March 31, 2018. (Released Jan 23, 2017).

* Approved XMM-Newton AO-16 Guest Observer Program for observations to be carried out during the period from May 2017 through April 2018. (Released Dec 2, 2016).

* Approved Stage-I Fermi Cycle 9 Guest Investigator Program proposals (Released Jul 18, 2016).

* Peer Review recommended Chandra X-Ray Observatory (CXO) Cycle 18 targets and proposals for observations to be carried out in a twelve-month period beginning about January 2017, 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 18, 2016).

* INTEGRAL AO-14 General Program of Observations to be carried out in the 12-month period starting on Jan 1, 2017. (Released Jun 28, 2016).

* NuSTAR Cycle 2 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 the Cycle 2 period from May 1, 2016 to May 31, 2017. Priority C targets will be observed on a "best-effort" basis. (Released Mar 04, 2016).

* Swift Cycle 12 recommended proposals, including both proposals for funding only and observing proposals, and targets; accepted Cycle 12 ToO proposals may be triggered until March 31, 2017. (Released Jan 19, 2016).

* Approved XMM-Newton AO-15 Guest Observer Program for observations to be carried out during the period from May 2016 through April 2017. (Released Dec 4, 2015).
