Evolution of the Low-Energy Photon Spectra in Gamma-Ray Bursts
A. Crider, E. P. Liang, I. A. Smith +6
We report evidence that the asymptotic low-energy power law slope alpha (below the spectral break) of BATSE gamma-ray burst photon spectra evolves with time rather than remaining c…
Broad band high energy observations of the superluminal jet source GRO J1655-40 during an outburst
S. N. Zhang, K. Ebisawa, R. Sunyaev +7
The X-ray/radio transient superluminal jet source GRO J1655-40 was recently suggested to contain a black hole from optical observations. Being a relatively close-by system (d \sim…
Low-Energy Spectral Features in GRBs
Michael S. Briggs
I discuss low-energy lines in gamma-ray bursts. The process of deconvolving gamma-ray spectral data and the steps needed to demonstrate the existence of a line are explained. Previ…
A Comprehensive Search for Low-Energy Lines in BATSE GRBs
Michael S. Briggs, David L. Band, Robert D. Preece +4
A computer-based technique has been developed to search bright BATSE gamma-ray bursts for spectral lines in a comprehensive manner. The first results of the search are discussed an…
Testing the Dipole and Quadrupole Moments of Galactic Models
Michael S. Briggs, William S. Paciesas, Geoffrey N. Pendleton +6
If gamma-ray bursts originate in the Galaxy, at some level there should be a galactic pattern in their distribution on the sky. We test published galactic models by comparing their…
Evidence from quasi-periodic oscillations for a millisecond pulsar in the low mass x-ray binary 4U 0614+091
E. Ford, P. Kaaret, M. Tavani +6
We have detected quasi-periodic oscillations (QPOs) near 1 kHz from the low mass X-ray binary 4U 0614+091 in observations with XTE. The observations span several months and sample…
Successive Continuation for Locating Connecting Orbits
E. J. Doedel, M. J. Friedman, B. I. Kunin
A successive continuation method for locating connecting orbits in parametrized systems of autonomous ODEs is considered. A local convergence analysis is presented and several illu…
Discovery of 800 Hz QPO in 4U1608-52
M. Berger, M. van der Klis, J. van Paradijs +11
We present results of RXTE observations of the low-mass X-ray binary and atoll source 4U 160852 made over 9 days during the decline of an X-ray intensity outburst in March 1996.…
Discovery of Sub-Millisecond Quasi-Periodic Oscillations in the X-Ray Flux of Scorpius X-1
M. Van der Klis, J. H. Swank, W. Zhang +5
We report the discovery, with NASA's Rossi X-ray Timing Explorer (RXTE), of the first sub-millisecond oscillation found in a celestial X-ray source. The quasi-periodic oscillations…
ROSAT HRI observations of the globular clusters M13 and M92
D. Fox, W. Lewin, B. Margon +2
We report on 40 kiloseconds of ROSAT HRI observations of the globular cluster M92 (NGC 6341) and 20 kiloseconds of observations of the globular cluster M13 (NGC 6205). We find that…
Search For Rapid X-ray Variability from the Black-Hole Candidate GRO J1655-40
D. J. Crary, C. Kouveliotou, J. van Paradijs +6
We have examined fifteen days of CGRO/BATSE data, obtained during the first outburst of the black-hole candidate source GRO J1655-40, to search for rapid variability of its X-ray f…
Correlation Between BATSE Hard X-ray Spectral and Timing Properties of Cygnus X-1
D. J. Crary, C. Kouveliotou, J. van Paradijs +7
We have analyzed approximately 1100 days of Cygnus X-1 hard X-ray data obtained with BATSE to study its rapid variability. We find for the first time correlations between the slope…
Spherical Harmonic Analysis of the Angular Distribution of Gamma-Ray Bursts
Max Tegmark, Dieter Hartmann, Michael Briggs +1
We compute the angular power spectrum C_l of the BATSE 3B catalog, and find no evidence for clustering on any scale. These constraints bridge the entire range from small scales, pr…
BATSE SD Observations of Hercules X-1
P. E. Freeman, D. Q. Lamb, R. B. Wilson +5
The cyclotron line in the spectrum of the accretion-powered pulsar Her X-1 offers an opportunity to assess the ability of the BATSE Spectroscopy Detectors (SDs) to detect lines lik…
Search for Supergalactic Anisotropies in the 3B Catalog
Dieter H. Hartmann, Michael S. Briggs, Karl Mannheim
The angular distribution of GRBs is isotropic, while the brightness distribution of bursts shows a reduced number of faint events. These observations favor a cosmological burst ori…
