Le 10 janvier 2014 De 10h30 à 11h30 Observatoire Astronomique - Grande Coupole Giovanni MANFREDI Institut de Physique et Chimie de Matériaux de Strasbourg (IPCMS) Cosmological simulations should in principle adopt a four-dimensional (4D) space-time to model the evolution of...
Le 20 décembre 2013 Andreas Eckart Universität zu Köln A fast moving infrared excess source (G2) which is widely interpreted as a core-less gas and dust cloud approaches Sagittarius~A* (SgrA*) on a presumably elliptical orbit. VLT Ks-band and Keck K'-band data result in...
Le 13 décembre 2013 Devaky Kunneriath Astronomical Institute of the Academy of Sciences, Prague Gas clouds are present in the centre of our galaxy, the Milky Way, where they orbit around the supermassive black hole, Sagittarius A*. Collisions between these clumps reduce their...
Le 6 décembre 2013 De 10h30 à 11h30 Lucio MAYER University of Zurich (Suisse) The theory of galaxy formation within the standard LCDM paradigm has faced several problems that in the past have generated serious doubts on the cosmological model itself. The progess of...
Le 29 novembre 2013 De 10h30 à 11h30 Lev Tal-Or Tel Aviv University (Israel) The photometric space-borne survey missions CoRoT and Kepler were designed mainly to discover transiting planets. However, they are capable of much more. Thousands of eclipsing binaries were detected...
Le 22 novembre 2013 De 10h30 à 11h30 Quentin Parker Macquarie University - Observatoire de Strasbourg A description of the importance of Planetary Nebulae (PN) in late stage stellar evolution will be presented with particular emphasis on PN research at Macquarie University...
Le 15 novembre 2013 À 10h30 Amphithéâtre Grande Coupole Markus Roth Kiepenheuer-Institut für Sonnenphysik, Freiburg, Germany The Sun is subject to sound waves that probe its interior. Observations of these solar oscillations have emerged as a powerful tool to gain...
Le 8 novembre 2013 De 10h30 à 12h00 Amphithéâtre - Grande Coupole Leslie Sage University of Maryland (USA) Nature is one of the world's leading scientific journals, publishing many papers that receive wide attention by the general public. But, Nature is very selective-- less...
Le 25 octobre 2013 De 10h30 à 12h00 Amphithéâtre - Grande Coupole Norbert Wex Max-Planck-Institut für Radioastronomie, Bonn Before the 1970s, precision tests for gravity theories were constrained to the weak gravitational fields of the Solar system. Hence, only the...
Le 18 octobre 2013 De 10h30 à 12h00 Amphithéâtre - Grande Coupole Frédéric VINCENT Centre Astronomique Nicolas Copernic de Varsovie (Pologne) Black hole systems can be affected by variable phenomena. The characteristic time of these variable phenomena scales with the mass...
