Galaksije do- prinose oko 5% mase jata, unutar-klasterski medij oko 10% mase i tamna tvar do 85% mase. Te strukture su nastale iz protojata galaksija. Protojato je rani oblik jata sa manje galaksija i sa uo£enom ve¢om gusto¢om broja galaksija u odnosu na ostale dijelove promatranog neba. -

The Shaw Prize The Shaw Prize is an international award to honour individuals who are currently active in their respective fields and who have achieved distinguished and significant advances, who have made outstanding contributions in culture and the arts, or who in other domains have achieved excellence. The award is dedicated to furthering societal progress, enhancing quality of life, and enriching humanity’s spiritual civilization. Preference will be given to individuals whose significant work was recently achieved. Founder's Biographical Note The Shaw Prize was established under the auspices of Mr Run Run Shaw. Mr Shaw, born in China in 1907, is a native of Ningbo County, Zhejiang Province. He joined his brother’s film company in China in the 1920s. In the 1950s he founded the film company Shaw Brothers (Hong Kong) Limited in Hong Kong. He has been Executive Chairman of Television Broadcasts Limited in Hong Kong since the 1970s. Mr Shaw has also founded two charities, The Sir Run Run Shaw Charitable Trust and The Shaw Foundation Hong Kong, both dedicated to the promotion of education, scientific and technological research, medical and welfare services, and culture and the arts. ~ 1 ~ Message from the Chief Executive I am delighted to congratulate the six distinguished scientists who receive this year’s Shaw Prize. Their accomplishments enrich human knowledge and have a profound impact on the advancement of science. This year, the Shaw Prize recognises remarkable achievements in the areas of astronomy, life science and medicine, and mathematical sciences. The exemplary work and dedication of this year’s recipients vividly demonstrate that constant drive for excellence will eventually bear fruit. -

In this document, we describe how detailed studies of stellar dynamics deep in the potential well of a galaxy offer several exciting directions in the coming decade. First, it will be possible to obtain precision measurements of the Galaxy’s central potential, providing both a unique test of General Relativity (GR) and a detection of the extended dark matter distribution that is predicted to exist around the SMBH. Tests of gravity have not previously been pos- sible on scales larger than our solar system, or in regimes where the gravitational energy of a body is >∼1% of its rest mass energy. -

Caption o The diminutive-looking object appeared as a dot next to a vast ring of icy debris encircling Fomalhaut. • Unlike other directly imaged exoplanets, however, nagging Credit: NASA, ESA, and A.
