New Interactive Black Hole Simulation Published 107
quaith writes "The New Scientist reports on a simulation just published in the American Journal of Physics that shows how the sky would appear in the vicinity of a black hole — if an observer could actually get near one. Using real positions of around 118,000 stars, the simulation shows how the bending of light, the frequency shift, and the magnification caused by gravitational lensing and aberration in the vicinity of the black hole affect the sky's appearance. The simulation is interactive and allows the user to explore the stellar sky around the black hole. The simulation offers a couple of modes: 'quasi static' or 'freely falling' and the sample videos are quite spectacular. The New Scientist has a writeup, with an embedded video . The original article citation is here (abstract only). The simulation, which runs on Linux or Windows, as well as sample videos, can be downloaded from the University of Stuttgart website."

Alain Riazuelo at the Paris Institute of Astrophysics similar stuff years ago and even published a special DVD in a French magazine. It is sad they do not credit him at all, not very ethical.

This has full data file, linux binary, and windows binary.
Also, this has been uploaded to Elbitz if you prefer private tracker.

Is the program code taken from Alain Riazuelo, or did he perhaps invent the theory behind Black Holes that made it possible to write the program from the article?
Because what is asked in research is only that the persons whose work the current publication is based on are credited, both for the sake of their achievement and to enable verification of theories that isn't only superficial (current publication).

I imagine you would first have to move to Germany, then get a job at the University of Stuttgart. Then ask the German government for funding before someone reminds you that universities provide their own funding and usually don't require much justification for the research they choose to produce.

How about playing Star Trek Online on one monitor while watching Farscape (via Netflix) on the other monitor?

Nit-pick - the thing you're thinking of is called an accretion disk [wikipedia.org], not an acceleration disk.
