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 …

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 …

Long-duration γ-ray bursts (GRBs) release copious amounts of energy across the entire
electromagnetic spectrum, and so provide a window into the process of black hole formation …

The localization of the short-duration, hard-spectrum gamma-ray burst GRB 050509b by the
Swift satellite was a watershed event. We report the discovery of the probable host galaxy, a …

Since the successful launch of NASA's dedicated gamma-ray burst (GRB) mission, Swift, the
study of cosmological GRBs has entered a new era. Here I review the rapid observational …

Gamma-ray bursts (GRBs) are fascinating events due to their panchromatic nature. We study
optical plateaus in GRB afterglows via an extended search into archival data. We …

In recent years, our understanding of gamma‐ray bursts (GRB) prompt emission has been
revolutionized, due to a combination of new instruments, new analysis methods, and novel …

I calculate the emission expected from a Poynting-flux-dominated gamma-ray burst (GRB)
flow in which energy is dissipated gradually by magnetic reconnection. In this picture, the …

We explore two possible models which might give rise to bright X-ray flares in gamma-ray
burst (GRB) afterglows. One is an external forward-reverse shock model, in which the shock …
