Measurements of Gamma-Ray Bursts (GRBs) with Glast
G. G. Lichti, M. Briggs, R. Diehl +9
One of the scientific goals of the main instrument of GLAST is the study of Gamma-Ray Bursts (GRBs) in the energy range from ~20 MeV to ~300 GeV. In order to extend the energy meas…
The GLAST Burst Monitor (GBM)
G. G. Lichti, M. S. Briggs, R. Diehl +9
The selection of the GLAST burst monitor (GBM) by NASA will allow the investigation of the relation between the keV and the MeV-GeV emission from gamma-ray bursts. The GBM consists…
Analysis of Line Candidates in Gamma-Ray Bursts Observed by BATSE
M. S. Briggs, D. L. Band, R. D. Preece +2
A comprehensive search of BATSE Spectroscopy Detector data from 117 GRBs has uncovered 13 statistically significant line candidates. The case of a candidate in GRB 930916 is discus…
X-Ray Spectral Behavior of the Relativistic Jet Source Cygnus X-3
M. L. McCollough, C. R. Robinson, S. N. Zhang +13
Cyg X-3 is an unusual X-ray binary which shows remarkable correlative behavior between the hard X-ray, soft X-ray, and the radio. We present an analysis of these long term light cu…
Spectral Hardness Decay with Respect to Fluence in BATSE Gamma-Ray Bursts
A. Crider, E. P. Liang, R. D. Preece +5
We have analyzed the evolution of the spectral hardness parameter Epk as a function of fluence in gamma-ray bursts. We fit 41 pulses within 26 bursts with the trend reported by Lia…
Kilo-hertz QPO in Island State of 4U1608-52 as Observed with RXTE/PCA
W. Yu, S. N. Zhang, B . A. Harmon +8
We report RXTE/PCA observations of 4U 1608-52 on March 15, 18 and 22 immediately after the outburst in early 1996. The persistent count rates ranged from 190 to 450 cps (1-60 keV).…
