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

CONNECTION BETWEEN ENERGY-DEPENDENT LAGS AND PEAK LUMINOSITY IN GAMMA-RAY BURSTS
We suggest a connection between the pulse paradigm at gamma-ray energies and the recently demonstrated luminosity distribution in gamma-ray bursts: The spectral evolution timescale of pulseExpand

Long-Lag, Wide-Pulse Gamma-Ray Bursts
Currently, the best available probe of the early phase of gamma-ray burst (GRB) jet attributes is the prompt gamma-ray emission, in which several intrinsic and extrinsic variables determine GRB pulseExpand

DETECTION OF SIGNATURE CONSISTENT WITH COSMOLOGICAL TIME DILATION IN GAMMA-RAY BURSTS
If gamma-ray bursters are at cosmological distances as suggested by their isotropic distribution on the sky and by their number-intensity relation then the burst profiles will be stretched in time,Expand

Further determinations of the gravities of cool giant stars using Mg I and MgH features
Surface gravities are deduced for Arcturus and five other cool giant stars. A temperature and an overall abundance are adopted for each object and the surface gravity is then found by requiring theExpand

Duration distributions of bright and dim BATSE gamma-ray bursts
We have measured the T(sub 90) and T(sub 50) durations of bright and dim gamma-ray bursts detected by the Compton Gamma-Ray Observatory's (CGRO) Burst and Transient Source Experiment (BASTE). TheExpand

Constraints on Association of Single-Pulse Gamma-Ray Bursts and Supernovae
We explore the hypothesis, similar to one recently suggested by Bloom and colleagues, that some nearby supernovae are associated with smooth, single-pulse gamma-ray bursts, possibly having noExpand

The gravities of K giant stars determined from [O I] and OH features
The oxygen abundances of four K giant stars, including Arcturus, are deduced from [O I] and OH line data. The OH lines used are vibration-rotation lines of the Δv=2 and Δv=1 sequences. SurfaceExpand

Gravitationally lensed gamma-ray bursts as probes of dark compact objects
If dark matter in the form of compact objects comprises a large fraction of the mass of the universe, then gravitational lensing effects on gamma-ray bursts are expected. We utilize BATSE and UlyssesExpand

GLAST, GRBs, and Quantum Gravity
The fast temporal structures and cosmological distances of gamma-ray bursts (GRBs) afford a natural laboratory for testing theories of frequency-dependent propagation of high-energy photons, asExpand
