We present the poster titled 'Probing into emission mechanisms of \thisgrb using time-resolved spectra and polarization studies: Synchrotron Origin? In this work, we have explored different aspects of the prompt emission and afterglow of multi-pulsed GRB 190530A (the sixth most fluent GBM burst detected so far) detected by the GBM and LAT and compared them with similar bursts. This poster presents the timing, spectral, and polarimetric analysis of the prompt emission observed using AstroSat and Fermi to provide insight into the prompt emission radiation mechanisms. Furthermore, we also report the earliest optical observations constraining afterglow polarization using the MASTER and the redshift measurement (z= 0.9386) obtained with the 10.4m GTC telescopes, making the burst the first case where both prompt emission and afterglow polarization measurements are constrained.
