  • E4: From MeV to TeV. Extracting the spectrum of cosmic rays at their sources over 6 orders of magnitude in energy | UnivEarthS
    currently 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

  • E5: Numerical Observatory of Violent Accretion systems NOVAs strong gravity and beyond | UnivEarthS
    plasma in the close neighborhood of compact objects is only properly described in the framework of general relativistic magnetohydrodynamic GR MHD The equations governing GR MHD are so complex that the only way to solve them is trough large scale numerical simulations The topic of the present demand is to sustain a computational effort dedicated to GRMHD simulations of accretion flows near compact objects and to link them to synthetic observations of the associated violent events one of the major themes within LabeX UnivEarths General Objective of the Project The quest to unveil the nature of the compact objects detected in the center of radio loud galaxies in X ray binaries and also at the center of the Milky Way is at the crossroads between high resolution time dependent multi wavelength observations and the coming of age of numerical GR MHD codes The project presented here plans to exploit this opportunity by setting a long standing collaboration between members of three teams involved in the LabeX UnivEarths which are already tackling individually the problem from the different angles of analytical and numerical studies observations and high performance code development While the french community is at the moment lacking a numerical code able to describe the dynamics of a magnetized plasma in a full GR framework the LabeX UnivEarths benefits from a unique conjunction where plasma numericists high energy observers and GR numericists are present in the same area and have had a good track record on common past projects By joining forces our aim is to sustain the development of such a GR MHD code in order to perform large scale simulations of plasma accretion onto compact objects and subsequently create an observation from it Another innovative feature of our code will stem from its ability to handle any kind of GR metrics not only conventional metric such as Schwarzschild or Kerr but also metrics of alternative non GR gravitation theories which generally do not have any analytical expression The three teams and interaction Our team while approaching a new subject linking their respective research is composed of people used to working together on a variety of topics such as GRBs and planet formation For this project we plan on using our distinct approaches to tackle the creation the first full GR MHD code coupled to a ray tracing code able to provide synthetic observations of the environment of compact objects AIM high energy observers axis led by J Rodriguez They are expert of multi wavelengths observations of compact objects and have access through dedicated and collaborative programs to a wide range of observations This broad range of data have allowed them to tackle the problems of accretion ejection connections and mechanisms prevailing in those systems including also the study of rapid X ray variability APC ADAMIS simulation axis led by F Casse and P Varniere Their expertise ranges from analytical to MHD numerical studies of the accretion ejection system They also do the extra step of linking their results
