查询词典 afterglows

For the first time, we study the radio afterglow behavior during the trans-relativistic phase of the fireball shock wave. Considering the trans-relativistic shock dynamic and the synchrotron self-absorption effect of the relativistic electrons on the radio emission, we find that the dense medium model can not only explain the fast decline of the X-ray and optical afterglows of GRB980519, but also account for its radio afterglow quite well.

我们首次研究了致密介质情形下射电余辉在跨相对论阶段的行为，发现考虑到激波的跨相对论动力学和相对论电子的同步自吸收效应对射电辐射的影响，致密介质模型既可以解释GRB980519的快速衰减的X射线和光学余辉，也可以很好地解释其射电余辉的特点。
