Synchrotron Radiation in the Afterglows of GRB 130427A and GRB160625B |
|
Abstract |
Gamma-ray burst (GRB) within the paradigm of the binary driven hypernova (BdHN) clearly points to its mildly relativistic regime during afterglow phase which is confirmed by early X-ray thermal component measurements around 100 seconds and optical emission lines measurement around $10^6$ seconds. Radiation in optical and X-ray band of the GRB afterglow within this paradigm come from the synchrotron radiation of relativistic electrons inside hypernova (HN) ejecta mainly magnetised by a newly created neutron star ($\nu$NS). To model the temporal behaviour of the GRB afterglow spectra we have developed a kinetic equation code which tracks the evoultion of injected electrons inside HN ejecta taking into account all the important energy losses and their temporal dependence. In this talk we present the basic physical elements of our code and the relevant results for GRB130427A and GRB160625B as a clear example. |
