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

Swift BAT Survey of AGNs
We present the results of the analysis of the first 9 months of data of the Swift BAT survey of AGNs in the 14-195 keV band. Using archival X-ray data or follow-up Swift XRT observations, we haveExpand

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

Suzaku observations of active galactic nuclei detected in the SWIFT BAT survey: Discovery of a "new type" of buried supermassive black holes
We present the Suzaku broadband observations of two AGNs detected by the Swift BAT hard X-ray (>15 keV) survey that did not have previous X-ray data, SWIFT J0601.9-8636 and SWIFT J0138.6-4001. TheExpand

A link between prompt optical and prompt γ-ray emission in γ-ray bursts
The prompt optical emission that arrives with the γ-rays from a cosmic γ-ray burst (GRB) is a signature of the engine powering the burst, the properties of the ultra-relativistic ejecta of theExpand

OSSE Mapping of Galactic 511 keV Positron Annihilation Line Emission
The Oriented Scintillation Spectrometer Experiment (OSSE) observations of the Galactic plane and Galactic center region have been combined with scanning observations by the Transient Gamma-RayExpand

Correlations of prompt and afterglow emission in Swift long and short gamma-ray bursts
TLDR
We present a large and uniform data set for correlation analysis of prompt and afterglow emission from gamma-ray bursts detected by the Swift mission. Expand

SUZAKU VIEW OF THE SWIFT/BAT ACTIVE GALACTIC NUCLEI. I. SPECTRAL ANALYSIS OF SIX ACTIVE GALACTIC NUCLEI AND EVIDENCE FOR TWO TYPES OF OBSCURED POPULATION
We present a systematic spectral analysis with Suzaku of six active galactic nuclei (AGNs) detected in the Swift/BAT hard X-ray (15-200 keV) survey: Swift J0138.6–4001, J0255.2–0011, J0350.1–5019,Expand

An infrared flash contemporaneous with the γ-rays of GRB 041219a
The explosion that results in a cosmic γ-ray burst (GRB) is thought to produce emission from two physical processes: the central engine gives rise to the high-energy emission of the burst throughExpand
