NuSTAR Bringing the High Energy Universe into Focus

 

For Proposers

NuSTAR has been approved to continue operations through 2020 (subject to review by the 2019 NASA Astrophysics Senior Review of Operating Missions) including a Guest Observer Program.
 
                                  Cycle-3 observations begin on 2017-06-01.
 
Opportunities to propose for NuSTAR observing time
 

2016-12-15

 

Chandra  GO Cycle-19 AO released  

Proposal due date is 6 pm EDT on March 15th, 2017. Up to 1 Ms of NuSTAR observing time is available for observations on 2018.

 

New for Chandra cycle-19: An additional 0.5 Ms of NuSTAR observing time has been set aside for Large or Very Large joint observing programs.

INTEGRAL  GO Cycle-15 AO released  

Proposal due date is 2 pm CEST on March 31st, 2017. Up to 100 ks of NuSTAR observing time is available for observations in 2018.

 
The total amount of time allocated to Guest Observations is 9.5 Ms (~50% of the total observing time per year) including up to 6.5 Ms of observing time awarded to selected NuSTAR GO program investigations. It is anticipated that approximately 50 investigations will be selected for implementation in each NuSTAR GO cycle.
 
Of the remaining time (~ 3 Ms):
 
  • up to 1.5 Ms of NuSTAR observing time is expected to be awarded to joint NuSTAR/XMM-Newton proposals submitted to the XMM-Newton Cycle 17 Call for Proposals. (See list of accepted proposals for cycle-16 on XMM-Newton OTAC results website)
  • up to 1.0 Ms of NuSTAR observing time to joint NuSTAR/Chandra observing projects submitted to the Chandra Cycle 19 Call for Proposals. Note that this includes up to 0.5 Ms reserved for V/LP programs.
  • up to 100 ks of NuSTAR observing time to joint NuSTAR/INTEGRAL observing proposals submitted to the INTEGRAL Cycle 15 Call for proposals. The deadline for INTEGRAL AO-15 proposals is March 31st, 2017.
  • up to 300 ks of NuSTAR observing time for joint NuSTAR/Swift proposals is expected to be available starting in Swift cycle-14, with proposals due in 2017 September.
  • As a service to the community "snapshot" (1 - 2 ks) observations are performed by NASA’s Swift mission for most NuSTAR observations (including GO programs).
 
For the most complete list of planned and observed targets as well as any ToOs that may be triggered before the beginning of Cycle 3 observations on June 1st 2017, please refer to the NuSTAR  Master Catalog at the HEASARC, which may be queried using either Browse or Xamin and the list of approved NuSTAR  ToO programs available on the NuSTAR  SOC website.
 
The remaining 50% of the observing time will be allocated through the NuSTAR  project as follows:
 
  • NuSTAR  legacy survey observations (~ 25% of the total observing time)
  • NuSTAR  PI discretionary time, including unanticipated ToO observations open to the scientific community (~ 15%)
  • Calibration observations, engineering tasks, and resolving operational issues (~ 10%).
