1Physics of the Cosmos Science Objectives Expand our knowledge of dark energyPrecisely measure the cosmological parameters governing the evolution of the universe and test the inflation hypothesis of the Big BangTest the validity of Einstein's General Theory of Relativity and investigate the nature of spacetimeUnderstand the formation and growth of massive black holes and their role in the evolution of galaxiesW44 SNRExplore the behavior of matter and energy in its most extreme environments
3CMB Polarization from space: Planck Planck will release full mission data in 9 spectral bands, and first release of polarization data in fall 2014.CMB polarization results expected to be sensitive enough to test BICEP2 results.The Inflation Probe Science Interest Group (IPSIG) has released a white paper entitled “CMB Polarization Measurements: 2015 and Onward”, which is posted on the NASA PCOS website in reaction to the BICEP2 result
4Euclid A visible and near-infrared telescope to explore cosmic evolution CURRENT STATUS:~50 U.S. scientists are members of the Euclid Consortium that will analyze the dataFirst experimental manufacturing run for the Euclid near-infrared detectors to in process (ESA). NASA is testing detectors from the ESA NRE phase.NASA will buy, test and characterize the flight infrared detectors starting in ~ 2015, depending on the NRE-phase experimental manufacturing run.NASA developing ground system node and U.S. science center (ENSCI: Euclid NASA Science Center at IPAC).ESA Cosmic Vision Mission, M-Class with NASA participation.1.2-m mirror, visible & near-IR images, spectra6 year mission surveying 15,000 sq. deg.Launch Date: Mar 2020HAS PASSED KDP-CScience Objectives:Euclid will look back 10 billion years into cosmic history.Probe the history of cosmic expansion (influenced by dark energy and dark matter) and how gravity pulls galaxies together to form the largest structures.The shapes of distant galaxies appear distorted because the gravity of dark matter bends their light (gravitational lensing). Measuring this distortion tells us how the largest structures were built up over cosmic time.Measuring how strongly galaxies are clumped together tells us how gravity influences their motions, and how dark energy has affected the cosmic expansion.
5Astrophysics Implementation Plan Physics of the Cosmos (PCOS): Scientific and Technical Stewardship for future missionsProvide scientific and technical stewardship for decadal-survey recommended missions:Of the six highly-ranked medium and large-scale space-based priorities in NWNH, three fall within the PCOS science program:LISA (Gravitational Waves)IXO (X-ray)Inflation Probe (medium-scale)NOTE: Although dark energy SCIENCE is within PCOS program, WFIRST is located within the Exoplanet ProgramNOTE THAT HALF OF ALL THE MEDIUM AND LARGE SCALE SPACE PRIORITIES FALL WITHIN THE PCOS PORTFOLIO.Note:Astrophysics Implementation Planupdate in process
6ESA’s L2 Advanced X-ray Observatory: Athena The Advanced Telescope for High Energy Astrophysics (Athena) has been selected for the ESA L2 slot. Launch date ~2028.NASA and ESA are discussing a potential NASA contribution.The Decadal Survey recommended an international partnership for an advanced X-ray observatory.NASA solicited applications for a U.S. representative on the ESA Athena Science Study Team. Randall Smith (CfA) is U.S. member. Robert Petre (GSFC) and Michael Garcia (HQ) are ex officio. First meeting July 2014.An ESA instrument AO will be released in early 2015.NASA’s FY15 budget request supports a potential Athena partnership.NASA will continue investing in technologies likely to be appropriate for an Athena contribution; investments include both directed and competed SAT investigations.NASA is budgeting for development of contributed flight hardware, U.S. participation in the Athena science team, and a U.S. data center and GO program.NASA has suggested the following types of contributions, limited to $ M for contributed flight hardware.Portions of the calorimeter instrumentInner mirror shellsPortions of the wide field imagerContribution to science data center (U.S. node)Updated August 11, 2014
7Future Gravitational Wave Observatory (Launch 2030’s) NASA and ESA are discussing a potential NASA contribution to ESA L3 which has the theme “The Gravitational Universe”ESA L3 planned for 2034 launchNASA is interested in contributing to this mission because it is responsive to the U.S. Decadal Survey. The U.S. Decadal Survey recommended an international partnership for a gravitational wave observatory.NASA is participating in ESA’s planned assessments for its L3 gravitational wave observatory.The partnership likely will be subject to Astro2020 decadal approvalNASA (PCOS) looks forward to community input via the GWSIG and PhysPAG regarding the futureNew chart March 17, 2014Please attend ThursdayMorning 10:30AM session“The Gravitational Universe”Organized by Guido Mueller
8LISA Pathfinder Status (including JPL project ST7) LPF Current Status: Late stages of integration with launch expected in July 31, 2015.Preparations for mission and science operations underway with numerous exercises/test campaigns planned for the coming yearESATransfer Orbit Thermal Test
9How can you interact with NASA’s Physics of the Cosmos program?
10Communicating with NASA Astrophysics via the Program Analysis Groups (PAGs) The Physics of the Cosmos Program Analysis Group (PhysPAG) serves as a forum for soliciting and coordinating input and analysis from the scientific community in support of the PCOS program objectives.The Program Analysis Groups (PAGs) include all members of the community interested in providing input to NASA on issues of strategic importance via analysis studiesPAGs hold regular public meetings.PAGs identify specific, well-defined topics for further detailed studies assigned to Study Analysis Groups (SAGs) as well as longer-standing, discipline-centered analysis groups – Science Interest Groups (SIGs). All are task forces of volunteers.Advisory CommitteesNASA Advisory Committee (NAC)ScienceCommitteeAstrophysics SubcommitteeExoPAGPhysPAGCOPAG
11PhysPAG and SIGsPhysPAG has five SIGs in operation for the Inflation Probe, Gamma Rays, Cosmic Rays, Gravitational Waves and X-rays.PhysPAG EC membership:J.

12PCOS community activities Encourage your finishing students and early-career postdocs to apply for the Einstein fellows’ programEinstein Fellows hold their appointments at a Host Institution in the U.S. for research that is broadly related to the science goals of the NASA Physics of the Cosmos program.The PhysPAG provides input on technology needs to the PCOS program office that are fed into the PCOS Annual Technology Report (PATR) each year. (Thanks for sending in 21 technology gaps during summer 2014!)Laura Blecha, 2012 Fellow
