Point symmetry in SNR as observational evidence for the jittering jets explosion mechanism of core-collapse supernovae

According to the jittering jets explosion mechanism (JJEM), intermittent accretion disks with varying directions launch jittering jets that explode core-collapse supernovae (CCSNe).  

Convective motion in the pre-collapse outer stellar core supplies seed perturbations to instabilities around the newly formed neutron star (NS), like the spiral modes of the standing accretion shock instability (spiral SASI), that amplify angular momentum fluctuations. 

These lead to accretion episodes via accretion disks onto the NS that launch several and up to few tens of pairs of jets along different directions, i.e., jittering jets.
In my talk, I will present a qualitative pipeline for analysis of SNRs demonstrated on G321.3-3.9, a SNR exhibiting a complicated structure, including point symmetries and "ears" in several wavelengths. 

I will detail the processing done and showcase the steps taken to examine the morphology of an SNR and denote the different features that could indicate the explosion mechanism, which we claim is the JJEM of CCSNe.
