In this study, we analyzed the spectropolarimetric data of the nearest superluminous supernova SN2018bsz to investigate the geometry of the ejected material and probed the asymmetric nature of this explosion. 2D spectral data have been reduced and analyzed using tools like IRAF to extract the 1D spectra. Further analysis has been done using Python-based routines. We delve into 2D spectral data to understand elemental composition, interactions with the circumstellar medium (CSM), and asymmetry in this SLSN explosion. By analyzing the spectropolarimetric observations, we have detected distinct polarisation patterns that shed light on the asymmetry and structural properties of this SLSN ejecta. Our analysis contributes to a broader understanding of SLSN evolution. |
