    • Program

  • Consideration of possibilities for astronomical observation in Submillimetron project. Submillimeter sky survey with high sensitive bolometer array using cryogenic telescope on orbit of International Space Station. Comparison with other space projects and ground-based instruments. Perspectives for submillimeter spectroscopy and microarcsecond interferometry.
  • Discussion of scientific tasks for submillimeter observations in fields of cosmology, extragalactic and galactic astrophysics.
  • Recommendations for international workshop on scientific objectives of Submillimetron project.

    • Results of discussion and recommendations

  • In current situation the Submillimetron is the only experiment promising to realize extremely high sensitivity 10-18 W/Hz-1/2 comparable to fundamental limit of fluctuation of the extraterrestrial background near its spectral minimum in submillimeter region 0.2-0.5 mm.
  • Submillimetron is the only experiment proposed for full-sky submillimeter-wave survey. It is the fundamental astronomical task to provide a bulk volume of information for cosmology, extragalactic astronomy, observation of Supernova stars, investigations of dust and molecules in our Galaxy, dust and cold bodies (Kuiper belt objects) in Solar system. A resulting catalog of more than 1 million objects should be very important for choice of objects for future large space and ground-based submillimeter telescopes and interferometers (ALMA).
  • Unique information for astrophysics should give results of measurements of submillimeter polarization, variability and spectral energy distributions (SED).
  • Complementarty of Submillimetron with other space experiments Planck and Herschel gives good perspectives for international scientific cooperation.

    • Recomendations:
  • to held an international workshop on scientific objectives of Submillimetron project in St.Petersburg, September 2002 (last decade, dates TBD);
  • to invite for workshop colleauges from Sweden, France, Italy, Finland, Germany, Russia with total number of participants 10-20;
  • to consider instrumental possibility for sky survey in narrow-band filters for measurements of submiilimeter dust features (width about 10%) and atomic/molecular lines (width <1%).
