Scientific paper

We present Rutgers/CTIO Fabry-Perot Imaging Spectrometer observations of the [O III] 5007 Å line of the oxygen-rich supernova remnant 1E 0102-72.9 in the Small Magellanic Cloud. Our data cube covers velocities from -2100 km/s to +2300 km/s with 100 km/s resolution, and for the first time reveals the complex three-dimensional structure of this remnant. The most prominent features are a number of rings of emission that are continuous in (X,Y,V) space, and bear striking resemblance to the Fe-Ni bubbles studied in recent numerical models. Using a simple kinematic model, we derive a free expansion age of 2100 years for E0102. .
