    of massive stars at cosmological distances To date neutrino and gravitational wave signals detected by current experiments could not be correlated with any precise astrophysical source GRBs are among the best electromagnetic counterpart candidates and a simultaneous detection with a GRB would represent the start of a new era for those two research fields namely the astronomy era These topics have been discussed in a lively international workshop organized in the framework of the LabEx UnivEarths in june 2014 at IPGP in Paris where about 80 scientists from all over the world have gathered E7 ONERA AIM Advanced time series analysis application to Microscope data Joel BERGÉ The MICROSCOPE mission will test the Equivalence Principle to an unprecedented accuracy in the near future Our WP aims to optimize the very demanding MICROSCOPE data analysis in particular to correct for the effect induced by missing data our results will be generalized to other experiments FRONTIER PROJECTS F1 IPGP Earth as a living planet from early ages to present dynamics Pascal PHILIPPOT This project addresses two fundamental problems of Earth evolution 1 The timing and mechanisms of oxygenation of the Earth atmosphere and shallow oceans and 2 the interplay between mantle processes crustal growth emergence of continental surfaces and the evolution of plate tectonics Sub project 1 PI Pascal Philippot focuses on drill core samples collected throughout the 2 45 to 2 2 Ga old Turee Creek Group Western Australia which represents the only continuous stratigraphic sedimentary section hosting the Great Oxygenation Event and the first global glaciation Sub project 2 PI Nikolai Shapiro focuses on the long lasting and discontinuous history of the crustal recycling and growth in subduction zones with field studies in Kamchatka and Caribbean regions F2 APC From Big Bang to the future of the Universe Yannick GIRAUD HÉRAUD The goal of this workpackage is to give to the labex team working in cosmology some specific help to strengthen their contributions in the major international observational projects of the domain This is developed along two principal axes detector development for B mode polarization of the CMB experiments and both data analysis and theoretical development to study the nature of Dark Energy in the forthcoming galaxy survey projects In both cases the aspects related to space projects are undertaken in close contact with the FACe and University Paris Diderot Campus Spatial F2a APC Support to PCCP Pierre BINÉTRUY As asked by the Scientific Committee most of the activity of the F2a project under the umbrella of the labex was devoted to outreach the continuation of the Teaching the Universe programme for highschool teachers and the preparation of a MOOC Massive Online Open Course on Gravity F3 AIM The transient catastrophic Universe Stéphane CORBEL Over the next decade new telescopes with increased sensitivity and larger field of view will open up the time domain to a wide range of astronomical fields Radio astronomy is leading this effort with the development of the SKA telescope The frontier project FP3 targets innovative

  • E4: From MeV to TeV. Extracting the spectrum of cosmic rays at their sources over 6 orders of magnitude in energy | UnivEarthS
    available data the spectrum of cosmic rays at their acceleration sites over more than six orders of magnitude in energy from the MeV to the multi TeV domain This task impracticable until very recently is now possible due to unprecedented observations of supernova remnants in both the millimetre and gamma ray domains of the electromagnetic spectrum and will constitute a crucial step towards the solution of the problem of the origin of Galactic cosmic rays Very recent observations in the near infrared and millimetre domain made possible to measure the Cosmic Ray CR ionisation rate in a handful of Molecular Clouds MC located next to SuperNova Remnants SNR In all these cases the SNR shock is interacting with the MC The ionization rates found in this way are significantly enhanced up to a factor of 100 with respect to the average value found in isolated MCs Ceccarelli et al 2011 Vaupre et al 2014 This striking difference is interpreted as an evidence for a strongly enhanced intensity of MeV CRs in those MCs which are interacting with SNRs Moreover the same clouds from which enhanced ionization rates have been inferred have been also detected in gamma rays see e g Rieger et al 2013 That also requires an enhancement in the CR intensity though in this case particles with much larger energies up to 10 100 TeV have to be invoked Both these facts provide a strong support to the popular but not conclusively proven yet conjecture that SNRs are the sources of CRs The goal of the proposed research is to combine these two observables and after complementing them with thorough and original theoretical investigations obtain information on the spectrum of CRs at their presumed sources within a huge interval spanning more than six orders of magnitude in particle
