Velocity Fields of Disk Galaxies
Peter Teuben
Two dimensional velocity fields have been an important tool for nearly 30 years and are instrumental in understanding galactic mass distributions and deviations from an ideal galac…
Simulation Software: Then, Now and Virtual Observatory
Peter Teuben
Like hardware, evolution of software has had a major impact on the field of particle simulations. This paper illustrates how simulation software has evolved, and where it can go. I…
Theory in a Virtual Observatory
Peter Teuben, Dave DeYoung, Piet Hut +5
During the last couple of years, observers have started to make plans for a Virtual Observatory, as a federation of existing data bases, connected through levels of software that e…
Immersive 4D Interactive Visualization of Large-Scale Simulations
Peter Teuben, Piet Hut, Stuart Levy +5
In dense clusters a bewildering variety of interactions between stars can be observed, ranging from simple encounters to collisions and other mass-transfer encounters. With faster…
High Velocity Clouds: the Missing Link
Leo Blitz, David N. Spergel, Peter J. Teuben +1
Hierarchical structure formation models predict the existence of large numbers of low velocity dispersion dark halos. Galaxy surveys find far fewer galaxies than predicted by analy…
Sgr A* and Company - Multiwavelength observations of Sgr A* and VLA search of ``Sgr A*'s'' in LINERs
Heino Falcke, W. M. Goss, L. C. Ho +5
We report first results from a multiwavelength campaign to measure the simultaneous spectrum of Sgr A* from cm to mm wavelengths. The observations confirm that the previously detec…
