| 内容記述 | I review recent results on GRB X-ray afterglows measured by the Swift X-ray Telescope (XRT). The XRT had observed over 290 X-ray afterglows of GRBs at the time of this meeting, obtaining > 80 % of the world total of GRB X-ray afterglows and > 70 % of the world total of GRBs with redshifts. I discuss general characteristics of X-ray afterglows as observed by Swift, and will then focus on a few of our most interesting discoveries. One of the most exciting of these was the recent "naked-eye" burst, GRB 080319B, with the brightest optical counterpart ever seen and one of the best-observed X-ray and optical light curves ever obtained. We interpret the bright prompt emission as the result of an extremely large bulk Lorentz factor, combined with a very narrow jet beamed directly at us, with Synchrotron Self-Compton emission from the UV/optical photons accounting for the gamma-ray emission. The X-ray and optical afterglows are interpreted as the result of a two-component jet, with the wide jet accounting for the optical afterglow, while the X-ray afterglow is initially dominated by the narrow jet until that component fades following its jet break. | |||||||
