To: Prof. Jordan Nash, Chair of PPAN CC: John Womersley Sheila Rowan Jenny Thomas Mike Bode Bob Warwick Dear Jordan, We are writing to you as chair of PPAN regarding the outcome of the recent STFC prioritization exercise. We recognize the tough decisions PPAN had to make given your decreasing budget over the next 3 years, but seek clarification on a number of issues where our initial FUAP advice appears to be different from your outcome. These include: * Cuts to the studentships, fellowships and grants. In our FUAP report, we ranked the maintenance of these items as our top critical priority and in person, we have continued to stress their importance. We echo the request in the recent joint statement from all the AP chairs that PPAN and Science Board revisit this decision immediately and try to mitigate the effect of such cuts to the next generation of UK scientists. In particular please review the removal of the entire PDF round this year. In our opinion, this is a very negative message to send especially in these tough times of youth unemployment. * The withdrawal from LOFAR which was highlighted by FUAP as one of our "Crown Jewels" over the next 5 years and was also "high priority" in the GBFR report. LOFAR addresses two of the four FUAP science themes (First Light, Extreme Astrophysics) and is a very cost- effective (for the UK) pathfinder to the SKA. At the Dec 18th briefing meeting with John Womersley, there was some confusion over whether FUAP could undertake an investigation of the decision to not support LOFAR and we request your advice on this. We believe the radio astronomy community would be open to sharing their constrained resources to partially support LOFAR. * The withdrawal from XMM-Newton, which was also highlighted by FUAP as one of our "Crown Jewels" over the next 5 years. XMM will be vital to addressing questions in Extreme Astrophysics and represents one of the most successful ESA missions ever flown. ESA has given top priority to continued support of XMM in the coming years and we are thus puzzled that this is not reflected in your decision, particularly given the vital core roles of the UK in data processing and instrument calibration. Continued support for XMM seems very cost-effective and we seek clarification if this withdrawal also includes UK scientists seeking exploitation funds via grants, studentships and fellowships? * We note that the UK has no access to future CMB experiments after Planck. Given the success of CMB research over the last decade in providing us with the cosmological standard model, we feel this could be disastrous for our standing in the worldwide cosmology community. We urge PPAN to look at this area of research asap as we fear it is barely sustainable now. * Access to telescopes in the northern Hemisphere. As discussed by John Womersley at the Dec 18th briefing, it is noticeable that the UK will potentially loose all telescopes in the north by 2012. This is against the advice of FUAP, NUAP and the GBFR. We seek your advice on how to deal with this outcome and stress that three of the FUAP science themes require access to the whole sky (Galaxies, Extreme Astrophysics, First Light). Not having such access will significantly damage our exploitation of highly ranked (and supported) facilities such as GAIA, Advanced-LIGO and Swift. We hope PPAN can provide a clear steer on these issues as John Womersley indicated on Dec 18th that some "fiddling" was possible. We do appreciate the impossible position you were placed in with a decreasing budget, but feel that some of the above issues are so important they are worth revisiting even in these tough financial circumstances. We are eager to help and ready to provide informed input (with public consultation if needed) over the coming month.
