Supernova Remnants Stay in Shape
Laura Lopez
MIT
Nearly 350 supernova remnants (SNRs) are now known in the Milky Way and nearby
galaxies, and these objects are excellent laboratories to study the debris of
SNe and their interaction with the interstellar medium. However, the complex
and heterogeneous nature of SNRs has hindered characterization of their
properties, precluding comparison of observations with theoretical predictions.
In this talk, I will highlight results from the first systematic study of the
morphological properties of SNRs. In particular, I will demonstrate that Type
Ia SNRs have statistically more symmetric and spherical emission than
core-collapse (CC) SNRs, and I will explore whether this result arises from the
distinct explosion mechanisms or the different environments of Type Ia/CC
progenitors.
