Unveiling the Dynamics of Supernova: A Use of Dynamic Mode Decomposition

Abstract In the present investigation, a supernova remnant (SNR) propagation inside the interstellar medium (ISM) is numerically simulated by solving the compressible magneto-hydrodynamic equations, employing a high-order finite volume methodology as implemented in the PLUTO solver. Flow features associated with the SNR propagated inside non-uniform ISM, is discussed thoroughly. The vortical coherent modes, identified through dynamic mode decomposition during the propagation of a SNR through a non-uniform ISM exhibit spatio-temporal decay behavior due to strong dissipation induced by the reverse shock and forward shock, respectively.
