Natal kick by early-asymmetrical pairs of jets to the neutron star of supernova remnant S147
Dmitry Shishkin, Ealeal Bear, Noam Soker
We analyze the bipolar morphology of the jet-shaped core-collapse supernova (CCSN) remnant (CCSNR) S147 and its neutron star (NS) kick velocity, and suggest that two pairs of unequ…

The Puppis A supernova remnant: an early jet-driven neutron star kick followed by jittering jets
Ealeal Bear, Dmitry Shishkin, Noam Soker
We identify a point-symmetric morphology of three pairs of ears/clumps in the core-collapse supernova remnant (CCSNR) Puppis A, supporting the jittering jets explosion mechanism (J…

Identifying a point-symmetric morphology in supernova remnant Cassiopeia A: explosion by jittering jets
Ealeal Bear, Noam Soker
We identify a point-symmetric morphology of the supernova remnant (SNR) Cassiopeia A compatible with shaping by at least two, and more likely more than four, pairs of opposite jets…
