EAS SYMPOSIUM 6: Dynamics of Galaxies and Galactic Nuclei
23-24 August 2007
Contact: Rainer Spurzem (Germany)
Link to EAS S6 webpage in Heidelberg
This Meeting is also a satellite meeting of the international collaboration MODEST (Modelling of Dense Stellar Systems), denoted as MODEST-7e. Please watch the MODEST sites and contact the responsible people of workgroups for questions.
The program consists of invited talks (40+5, I), contributed talks (20+5), and posters. Click on the author name to get the abstract (in a temporary format, just to see quickly the raw information).
This meeting will cover the progress in understanding the formation and evolution of stellar systems, collisionless galaxies as a whole, stellar disks, spiral waves, bulges and bars, dynamical interactions between all constituents of a galaxy, including dark matter, gas, and the central massive black hole. Dense collisional stellar systems, such as galactic and extragalactic star clusters, their formation and evolution, observational constraints, exotic objects in star clusters will be another topic of this meeting. Gravitational Waves are becoming a new branch of astrophysics. Star Clusters and Galactic Nuclei are prominent sources, due to black holes and other compact remnants forming and evolving in them. Efforts to detect gravitational waves are ongoing in Europe at present (ground-based Virgo, Geo600) as well as in the future (space based LISA). In this meeting there will be the opportunity to present and discuss the astrophysics of gravitational wave sources from dense stellar systems. Advances in computing hardware and software are fertilizing the field. In this EAS symposium new computing techniques, software and special hardware, as well as new approaches to cope with the increasing amounts of data and with code implementation and deployment via grid technologies can be discussed.
