Description
Daksha is an ambitious mission, expected to be the most sensitive high energy time-domain telescope. It will detect the highest number of GRBs and other high energy transients than any other mission. In addition to the interesting science with fainter and more distant sources, Daksha will also significantly impact the study of bright transients by measuring rapid spectral and temporal variations. A key feature is Daksha's ability to measure X-ray polarisation by utilizing multi-pixel events caused by Compton scattering of incoming photons. The large effective area, open CZT detectors, and the all-sky coverage make Daksha at least an order of magnitude more sensitive than the current generation satellites measuring GRB polarisation. The spectral and temporal analysis of GRB data allows us to identify models that are consistent with data; however, there are degeneracies among the various models. Different models give rise to a different degree of polarisation. A statistical analysis of GRBs' polarisation properties can help us constrain the models. In this work, we will present how Daksha and its capability of polarisation measurement will help us probe the physical processes related to GRBs and put constraints on the existing models related to GRBs.
