We study the ``normal'' decay phase of the X-ray afterglows of gamma-ray bursts (GRBs), which follows the shallow decay phase, using the events simultaneously observed in the R-band. The classical...
Takami, Kentaro, Yamazaki, Ryo, Sakamoto, Takanori, Sato, Goro
We show that the jet structure of gamma-ray bursts (GRBs) can be investigated with the tail emission of the prompt GRB. The tail emission which we consider is identified as a steep-decay component of...

We report the results of the Swift and XMM observations of the Swift-discovered long Gamma-Ray Burst GRB 060729 ($T_{90}$=115s). The afterglow of this burst was exceptionally bright in X-rays as well...
Toma, Kenji, Ioka, Kunihito, Sakamoto, Takanori, Nakamura, Takashi
The gamma-ray burst (GRB) 060218 has ~ 10^5 times lower luminosity than typical long GRBs, and is associated with a supernova (SN). The radio afterglow displays no jet break, so that this burst might...
GRB Radiative Efficiencies Derived from the Swift Data: GRBs vs. XRFs, Long vs. Short (2006)
Zhang, Bing, Liang, Enwei, Page, Kim L., Grupe, Dirk, Zhang, Bin-Bin, Barthelmy, Scott D., ...
We systematically analyze the prompt emission and the early afterglow data of a sample of 31 GRBs detected by {\em Swift} before September 2005, and estimate the GRB radiative efficiency. BAT's...
