Abstract : The combined analysis of GRB140512A (Oganesyan et al. 2017) with data from the\textit{ Swift}-XRT energy range of 0.5-10 keV, the \textit{Swift}-BAT energy range of 15-150 keV, and Fermi-GBM 8 keV-1 MeV, suggests a change in the spectral slope at a few keV (nearly at 8 keV), indicating a spectral break. The study also claims the spectrum change could have resulted from synchrotron self-absorption (SSA). We analyzed the synchrotron and SSA emission modeling for GRB 140512A. Our preliminary modeling indicates that the SSA emission occurred during the \textit{Swift}-XRT observations. The upcoming observations with Daksha– a proposed space mission to detect high-energy counterparts of gravitational wave sources at 1 keV to 1MeV(Bhalerao et al. 2024) would be a suitable candidate for constraining the SSA modeling of GRBs.
