Akademie věd České republiky
| Astronomy is an international science
and the Astronomical
fully integrated in the international cooperation. Virtually every
scientist at the Institute has partners abroad, which is evident from
the list of authors of the published papers. Medium and long-term stays
abroad are common and foreign scientists are being hosted at the
Institute. More formalized collaborations with foreign institutions and
organizations are listed below.
The solar department is in continuous collaboration with the Observatoire de Paris (Section de Meudon), which includes observations using the French-Italian telescope THEMIS on Tenerife. It also collaborates with the Astrophysikalisches Institut Potsdam, Kiepenheuer-Institut für Sonnenphysik, and Universität-Sternwarte Göttingen on the project GREGOR, a development and construction of a large solar telescope with diameter 1.5 m, currently being assembled on Tenerife, Canary Islands. Since 2002, the Solar Department has been included in the European Solar Magnetism Network, financed by the European Commission, in the framework of the program "Improving the Human Research Potential and the Socio-economic Knowledge Base" and coordinated by Utrecht University. A very close collaboration also continues with the Space Environment Center in Boulder, Colorado, USA, on the evaluation of data received from the joint space project HXRS. Also, a close relationship exists between our Institute and the Institute for Space and Astronautical Sciences (JAXA/ISAS) in Tokyo, Japan, under the joint project 'Study of the Physical Processes in Solar Corona'. As a result, at the end of 2004 a Letter of Agreement was signed between our Institute and the Solar Departments of ISAS and the National Astronomical Observatory Japan, which will enable to deepen our close collaboration with the Japanese scientists in the solar physics field.
The international cooperation of the stellar department pertains both experimental and theoretical fields. The echelle spectrograph HEROS was installed at the Cassegrain focus of the Ondřejov 2m telescope under the framework of the bilateral agreement of cooperation in astrophysics with Landessternwarte Heidelberg. It was used for observations at Ondřejov from August 2000 till March 2003. Cooperation with the Royal Observatory Brussels on improving the echelle spectra processing techniques was established. The Astronomical Institute is a member of the European Interferometry Initiative (EII), an FP 6 program trying to bring optical interferometry into mainstream astronomy and astrophysics. EII is part of the OPTICON activity. A bilateral agreement of cooperation with the Hvar Observatory (University of Zagreb, Croatia) enables our astronomers to make observations and solve problems in stellar photometry and studies of solar phenomena. An agreement of cooperation between the Academy of Sciences of Czech Republic and the Bulgarian Academy of Sciences was established. The agreement will foster joint programs in astrophysics.
The group of high-energy astrophysics has, besides the space projects mentioned later, an extended collaboration with the Instituto de Astrofisica de Anlalucia (IAA) in Granada, Spain, on investigation of gamma ray bursts and optical transients, including the operation of two BOOTES experiment robotic telescopes stations in southern Spain. A new collaboration has been established with the Paul Scherrer Institut (PSI) in Villigen, Switzerland, on scientific analyses of gamma ray burst data from the RHESSI satellite. Gamma ray bursts are also the main topic of collaboration with the Istituto di Astrofisica Spaziale e Fisica Cosmica (IASF) in Bologna within the framework of the common project of Italian CNR and Academy of Sciences of the Czech Republic. Blazars are investigated in close collaboration with the Tuorla Observatory in Finland.
The close cooperation with the Observatoire de Paris includes topics from dynamical astronomy, in particular the Earth's rotation. In cooperation with the Open University, London, a network for observations of bright fireballs and meteorite falls in the Australian desert is being built. Scientists from the department of interplanetary matter are also members of the international team organized by the International Space Science Institute in Bern to study the interaction of large meteoroids with the atmosphere. A large number of observatories all over the world participate in our program of asteroid photometry. The closest collaborator is the Space Science Institute in Boulder, Colorado.
Our Institute also collaborates with a number of organizations in space research. The collaboration with the European Space Agency (ESA) includes the high-energy astrophysics satellite INTEGRAL, in particular our participation on the onboard experiment Optical Monitoring Camera (OMC), and on the work of the INTEGRAL Science and Data Centre (ISDC) in Versoix, Switzerland. The further ESA astrophysical projects where the high energy astrophysics group is involved in are XEUS and LOBSTER. Within the LOBSTER project, collaboration with the Space Research Centre of the University of Leicester has been established. The solar department participates in the analysis of data from the SOHO satellite. Two PECS projects were approved by ESA for the Astronomical Institute (SOHO and INTEGRAL participation). The group of dynamics of satellite motion cooperates with ESA on the projects Solid Earth and SWARM. Other agreements of cooperation have been signed with the Astronomical Institute of the Russian Academy of Sciences and with the EUROCKOT (Germany, Russia). These last two enabled the launch of the Czech MIMOSA satellite. Cooperation also exists with NOAA, Silver Spring, USA, NASA Goddard Space Flight Center, Greenbelt, USA and GeoForschung Zentrum, Potsdam, Germany.
A special occasion for 2004 was the international project Venus Transit 2004. The project was organized by the European Southern Observatory and funded by the European Commission. The main goal was the education of young people and popularization of astronomy in connection with the transit of Venus in front of the solar disk on June 8, 2004. Two scientists from our Institute were members of the international stearing committee. Live images of the event from the Ondřejov telescopes were broadcasted over internet. A conference on this topic was organized in Brandýs nad Labem on May 7-9, 2004. Another international conference co-organized by the Institute was "Zdeněk Kopal's Binary Star Legacy", held in Litomyšl on March 31 to April 3, 2004.
The XXVIth General Assembly of the International Astronomical Union will be held in Prague on August 14-25, 2006. The preparation of this top astronomical conference already started and our Institute is heavily involved in the organizational work.
