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?

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):
US INTEGRAL Users Committee Meeting July 15, 2005 C. Shrader, NASA/GSFC INTEGRAL GoF 10
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
US INTEGRAL Users Committee Meeting July 15, 2005 C. Shrader, NASA/GSFC INTEGRAL GoF 11
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
US INTEGRAL Users Committee Meeting July 15, 2005 C. Shrader, NASA/GSFC INTEGRAL GoF 12
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
US INTEGRAL Users Committee Meeting July 15, 2005 C. Shrader, NASA/GSFC INTEGRAL GoF 13
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 GI Program Science
Major Concern: dearth of US 1st-Author Journal Articles:
US INTEGRAL Users Committee Meeting July 15, 2005 C. Shrader, NASA/GSFC INTEGRAL GoF 16
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 INTEGRAL Users Committee Meeting July 15, 2005 C. Shrader, NASA/GSFC INTEGRAL GoF 17

GSFC Co-I Activities
• B. Teegarden & K. Watanabe:– 511 keV: Collaboration with CESR/Toulouse.
– Analysis of diffuse galactic e+e- annihilation. Emission dominated by ~10° diam. Galactic bulge component. Disk component now emerging in data (3-4 sigma). Ps map recently generated – similar to 511 keV map.
– Participated in 5 papers. BJT 1st author on 511 keV limits in Galactic Plane.
• Gamma-Ray Line Search– Comprehensive search for lines, any energy or width in first year of SPI data.
– Analysis nearly complete. No new lines found. Both diffuse and point-like emission searched for.
– Examined spectra of ~100 sources from INTEGRAL Bright Source catalog
– Paper in preparation.

Data Analysis Workshop?
• GoF will query GI community on interest in INTEGRAL Analysis workshop
• Analogous activities:– XMM (at GSFC), ~7 attendees, mostly postdocs, grad students
– ISDC: second workshop planned for 10/2005 (~25 attendees, mostly grad students)
• Some technical/political details– hands on requires large DBs; guest accounts very restrictive
– problematic to bring foreign nationals on site
