We present results that trace the dynamics of two historical remnants, SN 1006 and SN 1572 (Tycho), for the past two decades. 21-cm radio images of each remnant were recorded during two previous epochs: 1983-1984 and 1991-1994. We obtained third-epoch images of both remnants from 2001 to 2003. After a direct comparison of images from these three epochs, we found the mean radio expansion rate of Tycho now agrees with a previous X-ray expansion study, and for the first time, we have measured the ...
We present results that trace the dynamics of two historical remnants, SN 1006 and SN 1572 (Tycho), for the past two decades. 21-cm radio images of each remnant were recorded during two previous epochs: 1983-1984 and 1991-1994. We obtained third-epoch images of both remnants from 2001 to 2003. After a direct comparison of images from these three epochs, we found the mean radio expansion rate of Tycho now agrees with a previous X-ray expansion study, and for the first time, we have measured the azimuthal expansion rate over the entire rim of SN 1006.
