Travel report of A. Chilingarian on Participation in the 37th COSPAR (Council of the Committee on Space Research) Congress in Canada, July 13-23

37th COSPAR (Council of the Committee on Space Research) Congress in Canada is the greatest event since the COSPAR foundation in 1960.2,500 scientists and students from 50 countries will present 1,500 reports inmore than 87 sessions covering all topics of Space Research: from planetary protection till jet dynamics in Supernovae explosions. I will attend the following sessions:

  • H0– Astroparticle physics;
  • D12 - Heliophysical processes: After the International Heliophysical year 2007; D22- New views on the Sun-Earth connections, Multispacecraft Imaging and in situ observations;
  • D23- Energetic Particle Events – Past, Present, Future;
  • E13 – Astrophysical shocks: Space Observations vs. Modeling;
  • E12 – High Energy Acceleration processes in Supernova Remnants, PWEe, Microblazars and Binaries: the keV to TeV connections;
  • PSW1 – Space Weather: Preparing to the next solar maximum
Among numerous new observations and concepts I can emphasize:

The new concept of particle acceleration in the solar flares during magnetic reconnections.Reconnection occurred not in unique, but in numerous sites in the active regions with enhanced magnetic field on the sun surface and in the corona.Numerous reconnection sites form an archipelagoes of  islands with distinct boarders, and particle acceleration takes place when electrons and ions cross this borders. This region above roots of magnetic loops in corona is the site of particle acceleration and is seen in the high energy roentgen radiation by satelliteX-ray observatories. The loops connecting  reconnection region and chromospheres are regions of particle trapping: due to magnetic pressure, particles approaching the sun surface are directed backward to the reconnection region and so on, till their energy reaches rather high values or till magnetic field lines open.

The X-ray satellite observatories and gamma-ray Cherenkov atmospheric telescopes present a new prove of magnetic field amplification in Supernovae Remnant till 0.2 mg due to nonlinear particle-plasma interactions and rather detailed morphology of the SNR I X-rays, gamma-rays and radio waves.

Multivariate campaigns of the stellar objects observations prove to me extremely successful in new physical inference and model selection. The Inverse Compton scenario of the TeV gamma-rays origin can be excluded, and, therefore, prove of Hadronic nature of TeV gamma-rays from SNR can be accepted as a most probable one. It is a very exciting achievement: after exploring cosmic rayflux ~100 years ago and after 50 years of intensive experimentation with surface air shower arrays, modern experimental techniques finally established the origin of cosmic rays

I will present the following reports:

  • "Surface Particle Detectors in Space Weather forecast”- has been accepted and scheduled for an oral presentation in scientific event PSW1;
  • "SEVAN particle-detector network located at Middle-Low latitudes for Solar Physics and Space Weather research”- has been accepted and scheduled for an oral presentation in scientific event D12;
  • Research of the Galactic Cosmic Rays from “knee” till “cutoff” (1017-1019) eV at Aragats Cosmic Ray Observatory”- has been accepted and scheduled for an oral presentation in scientific event E19.

On July 20 I participated in the COSPAR assembly meeting as a representative of Armenia to this organization. During the meeting it was decided that COSPARwill support the conference in Armenia: “Forecasting of the Radiation and Geomagnetic Storms by networks of particle detectors “(FORGES-2008), to be held on September 29 - October 3, 2008, in the Nor Amberd International Conference Center,  Armenia.
The topic of the meetings was directly connected with A1554 ISTC projects goals. During numerous discussions I came to the conclusion that goals of A1554 ISTC project and their planned realization summarized in the working plan are sound, very timely and achievable.
At the collaboration meetings with colleagues from on-going CRD international projects: (FP7 NMDB and INTAS) we discussed the current status of joint researches and planned new meetings and publications.
