## INTEGRAL Users Committee Meeting July 15, 2005

## US IUC 07/2005

- Agenda Item 1

## U.S. Guest Observer Program

- Success rate of US proposers remains good:
- 20% (AO-1) and 23% (AO-2), **31% (AO-3)**
- 19 US PI, 8 US Co-I proposals
- overall ESA AO-3: 58/106 approval rate
- Archive/Theory Program implemented as part of ROSS-2004
- 14 proposals received, 8 funded
- One half are theory
- $1.5M grant awards in support of GO + A/T

## U.S. Guest Observer Program

- Common  peer review evaluated GO budget requests and A/T proposals
- Unlike previous (AO-1&2), “mail-in” + phone con review of budget requests, face-to-face committee review was conducted
- Common review beneficial in optimizing use of grant funds
- committee feedback: C.D. handout
- Process worked smoothly, except for budget uncertainties at the time of the review

## Grant Administration

- General concern among GIs: grants take to long to process
- Two US observations occurred prior to completion of selection process
- Both are now funded
- Otherwise, grants GO are on schedule and all A/T programs funded, or awaiting GI paperwork
- Note, however, indeterminant temporal lag between 660 processing and GSFC grants office finalizing transfer

## Future Archive/Theory Program?

- Originally approved by NASA HQ for 1-year only
- Lobby for continuation?
- Problem: less than ~1 year from implementation to SR06
- Difficult to assess effectiveness by then
- Also budgetary considerations
- Should relative GO-A/T funding priorities be revisited?
- AO-4: ESA AO release in spring 2006
- Timeframe of SR06
- Changes to ESA program?

## US IUC 07/2005

- Agenda Item 2

## GOF Status, Activities

- Staff reductions:
- 1 programmer released due to budget cut
- K. Ebisawa no longer at ISDC (or tasked to INTEGRAL)
- Still 1 ISDC programmer; GSFC: 2 science FTEs + VB
- Major activities:
- US Archive implemented
- High-level products DB
- US AO-3 program underway
- ~6 1st-author INTEGRAL Journal articles

## Senior Review 2004 Summary

- “science case presented in the proposal was not as compelling as it could be”
- Science return “has been primarily limited to results on sources previously known”
- “concerned by the small number of US PIs (~25)”
- GOF should
- “improve software and analysis tools”
- “make data more readily accessible”

- Specific Criticisms & Recommendations (see H/O):

## Senior Review 2004 Summary

- “no plan or budget was presented for future EPO”
- Not in written evaluation, but lots of real-time discussion: Lack of US 1st author publications
- More on this shortly
- GI budget zero’d for FY07,08
- Must justify “overguide” request to restore
- Budgetary constraints may be more sever than for SR04

## Actions Taken

- US archive now fully functional;
- ~20-30 Gb downloads per month
- Improved browse access, high-level products
- Full reports (Sturner, Beckmann)
- Software: more difficult, as NASA is not responsible for management of INTEGRAL SW
- Some minor contributions (3 INTERGAL FTOOLS, unix shell scripts to bypass “ogcreate” level)
- Improved WWW services

## Actions Taken

- OSA 5 released this month (report to follow)
- Still calibration issues, but represents *vast improvement over system available at time of SR04*
- Percentage of US GOs (PI on ESA proposal) increased for AO3
- A/T program expands involvement
- Comparison w/XMM is favorable: 1/3 US PIs
- Known *vs* unknown sources??
- Actually, ~25% IGR sources previously un-cataloged

## EPO/PR

- EPO: Emulate Swift/XMM/GLAST model
- Contract to university group: ~1/3 FTE
- Some HEASARC EPO-team oversight
- Alternatively, could sponser another teachers workshop or analogous event
- Public Relations:
- Press releases: Sag A*, NGC 4388, IGR J16318-4838
- Popular articles: e+e-, Galactic Ridge

## US IUC 07/2005

- Agenda Item 4

## US GI Program Science

- Major Concern: dearth of US 1st-Author Journal Articles:

## US GI Program Science

- Propose that UC draft letter to AO-12,3 GIs expressing urgency to publish
- should discuss as a group
- specific actions?
- Problem: lots of “work in progress...”

- How can we improve this?

## US GI Program Science

- AGN:
- deep survey (Urry), 3C 120 jet (Marscher), Cen A (Rothschild), ULIRGs (Dudley), AGN catalog (Beckmann), TeV Blazar ToO (Krawczynski)
- XRBS: BHCs
- ToO campaigns (2 active, GRO J1655-40: Swank, Miller)
- Additional programs: Tomsick (4U1630-47), McCollough (Cyg X-3), Gehrels (Swift triggered transients)
- Search for obscured BHCs in Taurus region (Grindlay)
- PDS analysis (Rothschild)
- Böttcher (time dependent SED models)

- US GIs involved in all key areas of INTEGRAL Science:

- Some technical/political details
- hands on requires large DBs; guest accounts very restrictive
- problematic to bring foreign nationals on site
