The Partner Group does research on cosmic magnetic fields using radio astronomy methods. Magnetic fields are found in every astronomical object: the Earth, the Sun,planets, stars, pulsars, the Milky Way,nearby galaxies and in distant radio galaxies. The role of the magnetic fields in the cosmic universe has not been well investigated, mainly because of the difficulties of their observation.  相似文献

<正>"The MPG-CAS Partner Group led by Prof.HAN Jinlin from the Nationa Astronomical Observatories of China(CAS)has achieved great success in the determination of the magnetic fields o the Milky Way.The basis of this success was a cryogenic receiver with a polarim eter that was installed in China at the25m Nanshan Radio Telescope of the Urumqi Observatory.The receiver was a copy of a system installed in the 100m Effelsberg radio telescope of the Max Planck Institute for Radio Astronomy in Bonn,Germany.A very lively exchange of researchers at all levels took place.On  相似文献

A 6-cm receiving system with a polarimeter, made by engineers of German Max-Planck-Institute for Radioastronomy, has been installed to the 25 radio telescope in Urumqi, the capital of western China‘s Xinjiang Uygur Autonomous Region. The new instrument for Sino-German cooperation on radio astronomy will enable Chinese astronomers to measure the polarization of radio sources for the first time.  相似文献

It is easy for us to observe the magnificent spiral galaxies outside the Milky Way with a telescope. Although our own galaxy is also believed to have similar spiral arms to those observed in the universe, astronomers have difficulties in rendering the structure because we are living inside it.  相似文献

正Nestled in the mountainous landscape of Guizhou in southwest China,the Five-hundred-meter Aperture Spherical radio Telescope (FAST) is a single-dish radio telescope the size of 30 soccer fields.It has recently finished 15 months of listening to the sounds of the Universe.Data collected during this inaugural listening session and the pre-launch testing period has already resulted in more than 60 peer-reviewed publications.  相似文献

The Partner Group on Colloid and Interface Science is based on the International Joint Laboratory, established in the former Beijing Institute of Photographic Chemistry, Chinese Academy of Sciences (CAS), and was incorporated into the Center for Molecular Science of the Institute of Chemistry, CAS in 1999. The Partner Group aims at research on molecular assembly of biomimetic membranes and the synthesis of nano-structured materials by way of training younger Chinese scientists and making use of the advanced facilities in Germany. Both sides cooperate closely in sectors in which they have a common interest to push forward the development of related sciences in China. The group leader, Li Junbai, has received many awards and has obtained much financial support inside China. On the German side, the Partner Group is hosting or participating in several research and development projects commissioned by the Max Planck Society and the Deutsche Forschungsgemeinschaft (DFG). The Partner Group has thus secured goo  相似文献

The Partner Group does research in cosmology, focussing on the quantitative modeling of the structure and evolution of galaxies and galaxy clusters, the pattern of galaxies and of larger structures. The usual approach in this field is the dark matter paradigm, i.e. the assumption that the basic structures are laid out in a matter component of particles which interact only gravitationally. Numerical simulations of large scale and high resolution are used to follow the evolution of condensations of dark matter particles during cosmological evolution. Analytic models and detailed statistical investigations of astronomical data sets supplement the numerical work.  相似文献

<正>The formation and evolution of galaxies in a universe dominated by dark matter and dark energy is one of the most fascinating questions in astrophysics and generally in physics.Moreover the origin of galaxies has also attracted a lot of attention from the general public.To better understand the formation of galaxies in such a dark universe,scientists have made extensive studies using numerical simulations and analytical models.  相似文献

The first galaxies evolved only a few hundred million years after the Big Bang. But why do they have such a great variety of shapes and structures? How did the universe evolve as a whole? Two German-Chinese Partner Groups at the Max Planck Institute for Astrophysics in Garching are using observations and simulations to investigate how the early universe evolved: LI Cheng and Guinevere Kauffmann, as well as GAO Liang and Simon White.  相似文献

As one of the first Partner Groups which were initiated to foster scientific exchange and interaction between the Max Planck Society (MPS) and the Chinese Academy of Sciences (CAS), the Partner Group led by Lu Ke was established on April 1, 1999. During the past five years, the group has received substantial support from the CAS for equipment and from the MPS for personnel and travel expenses. Extensive and productive collaborations between the research staff and students of the Partner Group with several professors (departments) in the Max Planck Institute for Metals Research (MPI-MF) have led to significant advances in synthesis, mechanical properties, melting and superheating of nanostructured metals. The research is well recognized internationally and a substantial number of publications in high quality, peer-reviewed journals (including Science and Physical Review Letters) have resulted. At the MPI-MF, Ke Lu has collaborated with Manfred Ruhle and Reinhard Luck on crystallization studies, with Eric  相似文献

正Astronomers from the Chinese-French international lab LIA-ORIGINS have refuted the formerly well-established proof of dark matter in dwarf galaxies.They demonstrated that star motions in dwarf galaxies,which were believed to be governed by in-situ dark matter,are actually induced by gravitational forces of the Milky Way.Since the 1970s,astronomers have been convinced that dark matter is the main component of the matter in  相似文献

China's long and continuous cultural tradition offers scholars the special opportunity for cross-cultural studies in the long-term development of science. The Partner Group focuses on an exemplary case of such long-term development, the development of mechanical knowledge in China from antiquity to the early modern period. Research within the Partner Group is guided by a number of specific research questions, in particular the question of the interaction between practical and theoretical knowledge and the interaction between domestic and external knowledge traditions over a period of more than a millennium. In order to establish a cross-cultural perspective on the emergence and development of experiential science, the research is being coordinated with the current research project on the history of mechanical thinking at the Max Planck Institute for the History of Science.  相似文献

The first contact between Bao Xinhe and the Fritz Haber Institute (FHI) of the Max Planck Society goes back to 1989, when he was a Humboldt Scholarship holder in Germany. He worked at the FHI with Gerard Ertl on the surface and catalytic properties of Ag-cluster until 1995, when he returned to China and joined the Dalian Institute of Chemical Physics (DICP) under the Chinese Academy of Sciences. The cooperation with the FHI continued in 2000, when a Partner Group was established under the leadership of Robert SchlogI and Bao Xinhe. The group is devoted to the application of nano-related technologies in catalysis, with emphasis on controlled fabrication and dynamic characterization of nano-structured metallic particles and porous materials. In the past years, the cooperation has focused on various carbon nanotubes with special aligned structure and well-defined silver nano-particles in mesoporous materials. The nanostructured catalysts show high performance in methane activation at low temperature and in  相似文献
