The abscissa is in kilometers per second (km/sec), and the ordinate goes from 0 to 1 for each panel and reflects the relative strength of each component set. The absorption features shown are predominantly interstellar lines from gas between us and the supernova. However, the supernova is in a nearby galaxy, the Large Magellanic Cloud (LMC). The LMC is just beyond the Milky Way and is moving away from us. The labels above the second spectral strip show groups of interstellar components moving at different velocities, which cannot be resolved separately. The component groups 2, 3, and 4 are in the Milky Way galaxy, and the component groups 5 through 10 are in the LMC. The black dots are the data points, and the black line is a prediction (a model) including all of the subcomponents for what the interstellar spectrum should look like. The model and the data points agree very well. The ions represented are once-ionized nickel, once-ionized ... http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/fg7/fg7.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/grb980425/grb980425.dc.xml The ESO 184-G82 galaxy has loose spiral arms with many bright regions where stars are forming. The inset shows an expanded view of one of the star-forming regions. The arrow shows the location the 1998 supernova explosion. This supernova was also a gamma ray source, showing supernova are the origin of some GRB's. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/grb980425/grb980425.dc.xml Mon, 12 Jun 2000 12:00:00 GMT
