So what you see below is a plot of the plane of the Sagittarius dwarf orbit which is almost perpendicular to the Milky Way's disk. An image of an edge on disk galaxy was taken from the SDSS image archive and used to simulate the Milky Way. The coloration has been slightly altered to make it stand out more, but the dust lane can still be seen as the dark band that obscures the core of the galaxy. The Sun's position is marked with the green star. The white points are from a simulation modeling the disruption of the Sagittarius (Sgr) dwarf galaxy with the current position of the core indicated. The red dashed line indicates the directionality of the orbit. The cyan (blue) points are a subsampling of the stars we have found to be part of the Sgr tidal stream, while the magenta (pink) arrows indicate the directionality of the stream we found by analyzing the SDSS data. We have currently analyzed 2 wedges thus we have points and directions for those two volumes. The goal of this project, at least at current, is to be able to make all the white areas covered with cyan points such that we don't have a simulation but real data that defines the tidal disruption. That's where you guys come in; we need your help in analyzing all that area! ~Nate~ ID: 4195 · Rating: 0 · rate: / Reply Quote

I'm going to give a short presentation in about 5 weeks to my astronomers' league and THAT is a graphic and explanation that I can use that should make it pretty clear to just about anyone what you're doing! The presentation is going to be on all of the astronomy/astrophysics related BOINC projects, so obviously MW will be included. Hopefully that should drum up some more machines to do the work.
