NuSTAR Proposals and Tools


Additional opportunities to propose for NuSTAR time

Joint Swift and NuSTAR Observations

Currently NuSTAR and Swift have an arrangement which makes available joint observing time for both observatories. This resource allows observers to combine the powers of both observatories to bear on their scientific problems. This resource is extremely limited, so proposers should be sure to describe how their proposed observations exploit the unique capabilities of both observatories. While joint Swfit and NuSTAR proposals within the NuSTAR Guest Observer Program are now also possible, proposals for additional observation time can go through the Swift proposal process.

  • Swift Cycle 14. Is now closed. Approximately 300ks of joint Swfit and NuSTAR observation time was made available through the Swift Cycle 14. The start of observations is in April 2018.

Joint XMM-Newton and NuSTAR Observations

Currently NuSTAR and XMM-Newton have an arrangement which makes available joint observing time for both observatories. This resource allows observers to combine the powers of both observatories to bear on their scientific problems. This resource is extremely limited, so proposers should be sure to describe how their proposed observations exploit the unique capabilities of both observatories. While joint XMM-Newton and NuSTAR proposals within the NuSTAR Guest Observer Program are now also possible, proposals for additional observation time can go through the XMM proposal process.

  • XMM Cycle 17. Is now closed. Approximately 1.5 Ms of joint XMM-Newton and NuSTAR observation time was made available through the XMM-Newton Cycle 17 AO. The start of observations is in May 2018.
  • XMM Cycle 16. Is now closed. Approximately 1.5 Ms of joint XMM-Newton and NuSTAR observation time was made available through the XMM-Newton Cycle 16 AO. The start of observations is in May 2017.
  • XMM Cycle 15. Is now closed. Approximately 1.5 Ms of joint XMM-Newton and NuSTAR observation time was made available through the XMM-Newton Cycle 15 AO. The start of observations is in May 2016. Results can be found on the XMM-Newton OTAC Results page.
  • XMM Cycle 14. Is now closed. Approximately 1.5 Ms of joint XMM-Newton and NuSTAR observation time was made available through the XMM-Newton Cycle 14 AO. The start of observations is in May 2015.
  • XMM Cycle 13. Is now closed. Approximately 1.5 Ms of joint XMM-Newton and NuSTAR observation time was made available in the XMM-Newton Cycle 13 AO which was released on 27 August 2013. 62 such proposals were in fact submitted. Results can be found on the XMM-Newton OTAC Results page.

Joint Chandra and NuSTAR Observations

Currently NuSTAR and Chandra also have an arrangement which makes available joint observing time for both observatories. An opportunity to propose for NuSTAR observing time as part of this joint observing program is being made available through the Chandra calls for proposals.
  • Chandra Cycle 20. Up to 1 Ms of NuSTAR observing time is made available through the Chandra proposal process, which is due on 15 March 2018.
  • Chandra Cycle 19. Is now closed. Up to 1 Ms of NuSTAR observing time is made available through the Chandra proposal process, which is closed on March 2017.
  • Chandra Cycle 18. Is now closed. Up to 500 ksec of NuSTAR observing time was made available through the Chandra proposal process, which closed on March 15, 2016.
  • Chandra Cycle 17. Is now closed. Up to 500 ksec of NuSTAR observing time was made available through the Chandra proposal process, which closed on March 17, 2015.
  • Chandra Cycle 16. Is now closed. Up to 500 ksec of NuSTAR observing time were made available through the Chandra proposal process, which closed on March 13, 2014. Results of the review can be found here.

Joint INTEGRAL and NuSTAR Observations

Currently NuSTAR and INTEGRAL also have an arrangement which makes available joint observing time for both observatories. An opportunity to propose for NuSTAR observing time as part of this joint observing program is being made available through the INTEGRAL calls for proposals.

  • INTEGRAL Cycle 16: The due date is Friday, April 13, 2018, at 14:00 CEST. Up to 100 ks of NuSTAR observing time is made available through the INTEGRAL proposal process.
  • INTEGRAL Cycle 15.Is now closed. Up to 100 ks of NuSTAR observing time is made available through the INTEGRAL proposal process, which is closed on March 2017.
  • INTEGRAL Cycle 14. Is now closed. Up to 100 ks of NuSTAR observing time is made available through the INTEGRAL proposal process, which is closed on April 2016.
