Gamma Ray Bursts (GRBs) are the explosions which take place in the universe with the emission of extraordinarily high energies of the order of 1055 erg. These explosions were detected at redshift up to z = 9.4. Many theoretical models were used to explain the mechanism of GRBs. Here we have done the synchrotron modeling of the spectral energy distribution of the GRBs in the fast cooling and slow cooling regimes for the adiabatic blastwaves in Interstellar Medium (ISM) and wind environment. We have modeled the spectral energy distribution at different time intervals for GRB 130427A. GRBs help us to learn about the processes that cannot be studied under laboratory conditions and also enable us to understand the physics behind the formation and structure of matter in the Universe. GRBs are candidate sources of ultra high energy cosmic rays (UHECRs). High energy neutrinos can be produced by the interaction of these UHECRs with the GRB afterglow photons, which are produced in the blastwave.
