The association of GRB 060218 with a supernova and the evolution of the shock wave
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 explosion and its intimate link to aExpand

Relativistic jet activity from the tidal disruption of a star by a massive black hole
Supermassive black holes have powerful gravitational fields with strong gradients that can destroy stars that get too close, producing a bright flare in ultraviolet and X-ray spectral regions fromExpand

A short γ-ray burst apparently associated with an elliptical galaxy at redshift z = 0.225
Gamma-ray bursts (GRBs) come in two classes: long (> 2 s), soft-spectrum bursts and short, hard events. Most progress has been made on understanding the long GRBs, which are typically observed atExpand

Bright X-ray Flares in Gamma-Ray Burst Afterglows
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 indirect information on theExpand

Swings between rotation and accretion power in a binary millisecond pulsar
It is thought that neutron stars in low-mass binary systems can accrete matter and angular momentum from the companion star and be spun-up to millisecond rotational periods. During the accretionExpand

Introducing the CTA concept
The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve theExpand

An origin for short γ-ray bursts unassociated with current star formation
Two short (< 2 s) γ-ray bursts (GRBs) have recently been localized and fading afterglow counterparts detected. The combination of these two results left unclear the nature of the host galaxies of theExpand

Swift Observations of GRB 070110: An Extraordinary X-Ray Afterglow Powered by the Central Engine
We present a detailed analysis of Swift multiwavelength observations of GRB 070110 and its remarkable afterglow. The early X-ray light curve, interpreted as the tail of the prompt emission, displaysExpand

The First Survey of X-Ray Flares from Gamma-Ray Bursts Observed by Swift: Temporal Properties and Morphology
We present the first systematic investigation of the morphological and timing properties of flares in GRBs observed by Swift XRT. Expand
