The Burst Alert Telescope (BAT) on the SWIFT Midex Mission
Abstracthe burst alert telescope (BAT) is one of three instruments on the Swift MIDEX spacecraft to study gamma-ray bursts (GRBs). The BAT first detects the GRB and localizes the burst direction toExpand

GRB 090423 at a redshift of z ≈ 8.1
Gamma-ray bursts (GRBs) are produced by rare types of massive stellar explosion. Their rapidly fading afterglows are often bright enough at optical wavelengths that they are detectable atExpand

Gamma-Ray Burst Peak Duration as a Function of Energy
Gamma-ray burst time histories often consist of many peaks. These peaks tend to be narrower at higher energy. If gamma-ray bursts are cosmological, the energy dependence of gamma-ray burst timescalesExpand

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

A giant γ-ray flare from the magnetar SGR 1806–20
Two classes of rotating neutron stars—soft γ-ray repeaters (SGRs) and anomalous X-ray pulsars—are magnetars, whose X-ray emission is powered by a very strong magnetic field (B ≈ 1015 G). SGRsExpand

New family of binary arrays for coded aperture imaging.
We introduce a new family of binary arrays for use in coded aperture imaging which are predicted to have properties and sensitivity (SNR) equal to that of the uniformly redundant array (URA). Expand

Coded aperture imaging with uniformly redundant arrays.
Uniformly redundant arrays (URA) have autocorrelation functions with perfectly flat sidelobes. The URA combines the high-transmission characteristics of the random array with the flat sidelobeExpand

The 22 Month Swift-BAT All-Sky Hard X-ray Survey
We present the catalog of sources detected in the first 22 months of data from the hard X-ray survey (14-195 keV) conducted with the Burst Alert Telescope (BAT) coded mask imager on the SwiftExpand

We describe and discuss the global properties of 45 gamma-ray bursts (GRBs) observed by HETE-2 during the first 3 years of its mission, focusing on the properties of X-ray flashes (XRFs) andExpand
