We provide a comprehensive review of major developments in our understanding of gamma-
ray bursts, with particular focus on the discoveries made within the last fifteen years when …

With its rapid-response capability and multiwavelength complement of instruments, the Swift
satellite has transformed our physical understanding of γ-ray bursts (GRBs). Providing high …

We present a homogeneous X-ray analysis of all 318 gamma-ray bursts detected by the X-
ray telescope (XRT) on the Swift satellite up to 2008 July 23; this represents the largest …

The recent Fermi observation of GRB 080916C shows that the bright photosphere emission
associated with a putative fireball is missing, which suggests that the central engine likely …

A significant fraction of the long gamma-ray bursts (LGRBs) in the Swift sample have a
plateau phase showing evidence of ongoing energy injection. We suggest that many short …

Long duration gamma-ray bursts (GRBs) originate from the core collapse of massive stars,
but the identity of the central engine remains elusive. Previous work has shown that rapidly …

With the successful launch of the Swift Gamma-Ray Burst Explorer, a rich trove of early X-ray
afterglow data has been collected by its onboard X-Ray Telescope (XRT). Some interesting …

We present new observations of the early X-ray afterglows of the first 27 gamma-ray bursts
(GRBs) well observed by the Swift X-Ray Telescope (XRT). The early X-ray afterglows show …

Although the link between long γ-ray bursts (GRBs) and supernovae has been
established,,,, hitherto there have been no observations of the beginning of a supernova …

Gamma-ray burst (GRB) afterglows have provided important clues to the nature of these
massive explosive events, providing direct information on the nearby environment and …
