HEASARC Staff Scientist Position - Applications are now being accepted for a Staff Scientist with significant experience and interest in the technical aspects of astrophysics research, to work in the High Energy Astrophysics Science Archive Research Center (HEASARC) at NASA Goddard Space Flight Center (GSFC) in Greenbelt, MD. Refer to the AAS Job register for full details.
The start date for Cycle 5 has
been changed from June 1, 2019, to July 1,
2019; hence, Cycle 5 will last for a nominal
period of 11 months, see NRA clarification from February 19, 2019.
However, the observing time available for
Cycle 5 NuSTAR GO programs remains the same as
originally planned (~8.5 Ms). If there are projects requiring NuSTAR observations between
June 1 and June 30, 2019, such observations can be
requested
through unsolicited
NuSTAR Target of Opportunity (ToO) or
Directors Discretionary Time (DDT)
Observations. Due to the delay of the
Cycle 5 start time, approved Cycle 4
observations will extend into June, including
the opportunity to trigger Cycle 4 ToOs.
This NASA Research Announcement (NRA) solicits Guest Observer proposals
for NuSTAR. Approximately 8.5 Ms of time will be available
in the observing period June 1 July 1, 2019 - May 31, 2020. $3.0M in
funding will be made available to support the analysis of targets
accepted at priority A, B or C. Priority C targets will be observed
on a "best-effort" basis. Target proposals will be considered from
both US and foreign PIs.
Data from approved GO observations, with the exception of Target of Opportunity (ToO) observations,
have a nominal one-year exclusive-use period commencing at the time of receipt of the
processed data by the observer.
Data from peer review approved ToO observations have a six-month exclusive-use period.
Only PIs affiliated with, and located at,
a US institution will be eligible for funding for accepted
NuSTAR proposals through NASA. As part of the NuSTAR Cycle 5 program, up to 1.5 Ms
of XMM observing time, up to 300 ks of Swift observing time, and up to 250 ks of NICER observing time will be made available for
coordinated observations with NuSTAR.
A total of up to 2 Ms of NuSTAR Cycle 5 observing time will be made available for a new Large Program (LP) category. The minimum exposure time for LPs is 500 ks, and such proposals will have an additional page of text to describe the proposed program. Data from approved Cycle 5 LPs will have a one year exclusive use period after which the data will be placed in the public archive. A single-trigger ToO may be proposed as part of an LP (e.g., where a long observation is needed after the initial trigger). An approved LP with a ToO would have a six-month exclusive use period.
Joint Observing with NICER
Proposals for joint NuSTAR/NICER programs will be accepted up to a total of 250 ksec of NICER observing time. Joint proposals must provide a compelling justification of the need for both the NuSTAR and NICER data for achieving the primary science goals and receive a Category A or B rating to be considered for acceptance. NICER data sets obtained through approved joint NuSTAR/NICER proposals have the standard NuSTAR exclusive-use period and will be released publicly via the HEASARC data archive. Joint NuSTAR/NICER ToO proposals are only allowed for known sources (i.e., with known coordinates) in Cycle 5.
Additional details concerning Cycle 5 are given in the NuSTAR NRA.
There will be a two-phase proposal process. Phase one is for observing proposals. Phase two is for budget proposals for successful phase one proposers who were awarded priority A or B targets. Only observing proposals will be accepted at this time.
Proposal submission is done via the HEASARC ARK/RPS on-line system. Hard-copy submission is not required. The following
elements are required:
Proposal form (cover page & general form, and one or more
pages of the Target form) generated by, and submitted through, ARK/RPS.
Scientific justification in PDF format, not exceeding 4
pages for a Regular and 5
pages for a Large Program proposal, to be uploaded through ARK/RPS.
The following should not be submitted:
The PI's institution's own cover page.
Supporting material (e.g., Curriculum Vitae, pending/current support).
Formatted electronic copies of the ARK/RPS form.
Hard copies of any of the above, including electronically
required elements.
We provide below some key details for NuSTAR Cycle 5.
For further details, consult the
ARK/RPS help file.
Cover Page
Institutional endorsement is not required by NASA in NuSTAR
phase 1 proposals. Use the endorsement-related entries only if
they are required or desired by the PI's institution.
In addition to investigations utilizing NuSTAR observations only, proposals involving coordinated observations with the XMM-Newton observatory NICER observatory, and/or Swift observatory can also be proposed during Cycle 5. Proposals for joint NuSTAR-XMM, NuSTAR-NICER or NuSTAR-Swift observations should be indicated by clicking the Joint proposal section of the ARK/RPS form, and inputting the requested XMM and/or Swift exposure time in each target form.
Proposers may submit the same proposal to XMM AO-18 and NuSTAR Cycle 5. However, the XMM-Newton AO-18 approved program will be taken into account during the NuSTAR Phase 1 review and duplicate observations of the same targets by NuSTAR will typically not be awarded. Similarly, Proposers
may submit the same proposal to Swift AO-15 and NuSTAR Cycle 5 as well as NICER AO-1 and NuSTAR Cycle 5. However, the Swift AO-14 approved program will be taken into account during the NuSTAR Phase 1 review and duplicate observations of the same targets by NuSTAR will typically not be awarded.
Joint proposals for NuSTAR observations with Chandra or Integral cannot be submitted in response to this AO. However, NuSTAR does have separate agreements with Chandra and Integral for coordinated observations. Please see the main Proposals and Tools page for more information.
General Form
To facilitate checking for conflicts of interest during the peer review process, the co-I's institution must be chosen from the menu (thereby enforcing a uniform set of names). Please check the list of institutions and contact
the RPS team as soon as possible if your co-I's institution is not on this
list.
Up to 25 co-investigators can be entered into the RPS form. Only the first 10 will appear on the PDF versions of the form. The full list will
be available for conflict checking and will be provided to proposal reviewers.
Note that bilateral collaborations between scientists affiliated with institutions from the USA and the People's Republic of China (PRC) are not allowed by United States Federal law. Multilateral collaborations that involve scientists from institutions in the USA, the PRC, and other countries are allowed, however. Please refer to the PRC FAQ for ROSES for details.
Target of Opportunity (ToO) proposals will be accepted in response to this AO.
Target Form
Time Constraints: A target is considered as "Time Constrained" if any of the following sections of the target form are marked as 'Yes':
Position angle dependent
Moving Object
Monitoring Program
Phase Dependent
Time Constrained
See the NuSTAR RPS help page for more information about these fields.
In addition, observations coordinated with other ground- or space-based
observatories are considered as time constrained.
Note that time-constrained observations designated Category A or B will be given highest priority for scheduling during Cycle 5. Time-constrained observations of Category C targets will be executed on a best-effort basis. Time-constrained Category A and B observations not scheduled during Cycle 5 may be carried over to Cycle 6 where warranted by scientific or operational circumstances (e.g., in the case of coordinated observations with other space- or ground-based observatories). Category C time-constrained observations not scheduled during Cycle 5 will not be carried over to Cycle 6.
Proposers should include a summary of details that are
necessary for scheduling and observation planning (constraints,
observing mode) in the Remarks box for each
target.
Sources with fluxes > 10-11 ergs s-1
cm-2 within 5° of the target may cause increased non-uniform
background gradients due to stray light. Users should check observations for
potential stray light contributions using the tool that is available
at the NuSTARSOC web site. If a field is designated as having a "Potential stray light issue", proposers should submit a request for a feasibility analysis to nustar-help@srl.caltech.edu at least 2 business days prior to the proposal submission deadline.
The minimum exposure for NuSTAR targets is 20 ks. If the proposer is also requesting XMM, NICER, and/or Swift time, the minimum exposure times for these telescopes are 5 ks, 1 ks, and 1ks, respectively.
Estimated Count Rates:
Expected total band (3-79 keV) count rate of the source in counts/second for both modules in a 50% PSF extraction with no deadtime.
Note that the time available for observations of bright sources (100 counts/second) is limited to 1 Msec.
Target of Opportunity (ToOs):
A total of up to 500 ks of NuSTAR Cycle
5 observing time will be made available for proposals to observe ToOs. Single-trigger ToOs that are part of a Large Program are not held to a 500 ks exposure time limit.
Proposals with a preferred response time less than 48 hours will be evaluated based on the assumption that the minimum response time is 48 hours. A more rapid response time than 48 hours will be accommodated on a best-effort basis.
For ToO observations that are to be triggered from a class of objects:
Complete one target form per trigger only, specifying "0.0" for both the R.A. and Dec. fields and providing a generic target name, and, if applicable, enter a list of potential target names in the ToO Remarks field. If the list of targets is too long to fit in the TOO Remarks field, include the list in the scientific justification instead and put a note in the ToO Remarks to look there for the list.
For ToO observations that are to be triggered from a list of specific named objects: Complete one target form per object and trigger criterion even if you ask for time for a subset only. For each ToO proposal the "Maximum Total Time Requested for ToOs" field must be provided. If you ask for time for a subset only, this number will be smaller than the automatically calculated summed exposure time for all target forms.
Remember that ToO proposals will not be accepted for either a core
collapse supernova in the Local Group or a Type 1a closer than the
Virgo Cluster. Also note that it is the responsibility of the PI of an
accepted ToO proposal to alert the NuSTAR SOC when the trigger
conditions for their accepted ToO have been satisfied (via
http://www.nustar.caltech.edu/page/too_policy). For more details see
AO section 1.3.3.
After completing all fields for a proposal in ARK/RPS, use the
Verify button to confirm
that all required entries exist and conform to the expected format.
Forms that pass verification can then be submitted. ARK/RPS allows
PIs to continue to modify submitted proposals
until the deadline, so there is no penalty for submitting the proposal
form early.
The LaTeX, PostScript, and PDF buttons of
ARK/RPS can be used to generate formatted versions of the proposal forms.
Although it is often useful for the PIs to keep formatted copies of the forms
for the record, it is not a required part of the proposal submission process.
The scientific justification for a standard and ToO program must not exceed
4 Letter size pages. The scientific justification for a large program must not exceed
5 pages. Page limits include figures and references.
The scientific justification can be
generated using the software of the PI's choice, as long
as it is converted to PDF format before submission. However, the font size and margings should meet the
proposal style format requirement described in NASA Guidebook for Proposers.
We suggest that proposers use the LaTeX template or
the Word template for the scientific justification. When
using these templates, the user should double-check that the top, botton, right
and left margins are at least 1 inch.
Content
Proposals should include a description of the scientific
objectives; justify the choice of target(s); show that existing
data (previous X-ray observations or at other wavelengths)
are insufficient to achieve the objectives; justify the choice
of NuSTAR over other existing observatories (preferably
linked to some unique characteristic of NuSTAR);
and demonstrate the feasibility of the proposed observation
and analysis.
Proposals for targets already observed by NuSTAR are
allowed, but must include a justification for an additional
observation, such as a much longer exposure, different pointing
position within an extended object, or different observing window for a
variable object. Observed and/or approved NuSTAR
targets can be found using the HEASARC/Browse numaster table or by using NuSTAR
As-Flown Timeline.
Conflicts with Legacy Survey Targets
Observations of targets accepted through the Cycle 5 Call for Proposals will take precedence over legacy program observations of those targets. The status of legacy survey target observations can be found in HEASARC's numaster table by selecting "EGS", "ELS" or "GLS" for the obs_type keyword.
A list of approved NuSTAR ToO programs in the NuSTAR, joint NuSTAR/XMM, joint NuSTAR/Chandra, joint NuSTAR/Swift, and joint NuSTAR/INTEGRAL
GO programs can be found on the NuSTAR SOC page.
The length of the observation should be justified based on the
specific scientific objectives, preferably using simulations or
scaled from prior NuSTAR observations of a similar source.
However, the minimum NuSTAR observing time for a target is
set at 20 ksec.
U.S. PI's whose Phase-1 proposals are assigned a Category A or B rating by the peer review panel or accepted as a Large Program will be invited to submit a Phase-2 (cost) proposal.
Note that limited funding for the support of costs such as travel expenses associated with presentation of the results at a scientific conference, page charges, etc., will be held in reserve for Category C proposals executed during Cycle 5. No budget proposal is due at this time from PIs of proposals with only Category C targets.
Subject to acceptance of the associated Phase 2 cost submission, proposals for standard-mode observations (excluding proposals involving ToO or time-constrained observations) assigned a Category L, A or B rating will be eligible for funding immediately. Due to the uncertainty of their execution, the remaining accepted Phase 2 proposals will become eligible for funding only after the proposed observations have been carried out.
US co-Is on proposals with non-US PIs are
not eligible for funding.
Phase 2 (budget) proposals are submitted
through NASA's NSPIRES system.
The Phase 2 budget proposal deadline is August 15th, 2019.
US PIs of proposals with TC, or ToO observations
are invited to
submit a budget proposal by the August 15th, 2019 deadline. However,
the PIs of these programs
will not receive funding until a target from their program is observed.
Note that limited funding for the support of costs such as travel expenses associated with presentation
of the results at a scientific conference, page charges, etc., will be held in reserve for Category C proposals executed during Cycle 5.
As with all NASA ROSES proposals, final institutional
submission is required. Please leave enough time for your
institutional process. If your institution requires a NASA grant
solicitation number, it is NNH18ZDA001N-NUSTAR.
To submit a Stage 2 proposal, follow these basic steps:
Log on to NSPIRES. If
you do not have an NSPIRES account, you will need to create one and
affiliate with your institution.
On your NSPIRES home page, click on "Proposals/NOIs."
Click the "▸Create Proposal" button.
Select "Solicitation." Even though your proposal
has already been selected via phase 1, do not select "Prior-phase
Proposal."
Enter proposal information and your institutional affiliation.
When proposal elements are complete, use the "Release to Org"
button to release the proposal to your institutional proposal office.
Your institutional proposal office must then perform the final proposal submission.
A Phase-2 cost proposal consists of:
Cover page (via NSPIRES forms)
The abstract (via NSPIRES forms)
The budget justification (12pt minimum font with reasonable margins), not to exceed two pages, including: a) a breakdown of the work assignments for all funded investigators, b) any major purchases including workstations, c) proposed scientific travel, d) publication costs, and e) any cost sharing applied to this project
Confirmation of commitment (via NSPIRES forms) from any unfunded but essential personnel and from any necessary observing facilities on which time is not granted through the NuSTAR proposal review process
A listing of any current and pending support
A budget prepared according to the guidelines of the PI or Co-I institution, detailing the requested itemized expenditures
All required government certifications
A 1-2 page CV for each PI or Co-I requesting support
Please note that only one institution (e.g., PI institution only) award is allowed for NuSTAR Cycle 5 Phase 2 proposals. If Co-Is requesting support, please do budget this as a sub-award. The period of performance must be one year, and a recommended start date for the phase 2 proposal is Oct 1, 2019. Grants for proposals with "regular" A and B targets will be processed after the cost proposals are reviewed. Since ToO and time-constrained target observation grants will be issued only after the observation(s) take place in those cases the PI may want to use a later start date for planning purposes. Note that in either case the relevant start date for year of effort will be when the grant is issued by NSSC. If the grant needs to be extended beyond one year, please submit the No-Cost Extension request at least three months in advance of the end date of the period of performance.
