Un résumé des différents points forts et faiblesses de chaque projet sera présenté, avec une insistance particulière sur le caractère complémentaire des mesures et des découvertes possibles avec chaque outil, et leur impact sur la compréhension globale des origines de notre Univers et des interactions sous-jacentes. Cette vue d'ensemble devrait permettre de participer activement à la dernière demi-journée de l'École..

In the last few years a change of paradigm occurred in the field of black hole research. We now believe, that stellar mass black holes are created in powerful gamma ray bursts. Stellar remnants of the first generation of stars have very likely been the seeds of supermassive black holes, which we find dormant in the centers of most nearby galaxies - including our own Milky Way. A tight correlation between black hole mass and the global properties of their host galaxies indicates a co-formation and evolution of black holes and galaxies. The X-ray sky is dominated by a diffuse extragalactic background radiation, which our team, together with others, was able to resolve almost completely into discrete sources using the X-ray satellites ROSAT, Chandra and XMM-Newton. Optical and NIR follow-up identifications showed, that we observe the growth phase of the population of supermassive black holes throughout the history of the Universe. The accretion history derived from X-ray observations shows, that the black holes have been formed together or even before the bulk of the stars in galaxies. Major mergers between two galaxies seem to play an important role in the feeding of black holes. In a nearby merger event we could identify a double supermassive black hole in a single galaxy for the first time, which will merge in the future. In addition, we discovered several normal galaxies, in which an otherwise dormant black hole disrupts and swallows a normal star, which came too close. In this seminar I try to put these findings into a closed scenario about the formation and evolution of black holes. In addition I will discuss the roles and discovery potential of the proposed X-ray observatories DUO, ROSITA and XEUS.

During these sessions, Tom Kyte of Oracle Corporation will cover the following topics:# The Tools Tom uses, # The Top 5 things done wrong over and over again, # Building test cases, # Oracle 10g "cool features" Speaker Bio:Tom Kyte is the Vice President, Core Technologies for Oracle Government, Education and Healthcare. Before starting at Oracle, Tom Kyte worked as a systems integrator building large-scale, heterogeneous databases and applications, mostly for military and government customers. He spends a great deal of his time working with the Oracle database and, more specifically, working with people who are working with the Oracle database. Tom Kyte is the Tom behind the AskTom web site, answering people's questions about the Oracle database and its tools (http://asktom.oracle.com/). He is also the author of the AskTom column in http://www.oracle.com/technology/oramag/oracle/current.html Oracle Magazine, and the author of Expert One-on-One Oracle (Apress, 2003), Beginning Oracle Programming (Wrox Press, 2002), and Effective Oracle by Design (Oracle Press, 2003). These are books about the general use of the Oracle database and how to develop successful Oracle applications..
