RXTE Broad Band X-ray Spectrum of the Burster 1E1724-3045
J. F. Olive, D. Barret, L. Boirin +1
The X-ray burster 1E1724-3045 located in the globular cluster Terzan 2 is known as one of the persistent (though variable) hard X-ray sources as shown by the SIGMA observations of…
Discovery of High Frequency Quasi-Periodic Oscillations in 4u1915-05
D. Barret, L. Boirin, J. F. Olive +4
The type I X-ray burster and dipper 4U1915-05 (also known as XB1916-053) was monitored by the Rossi X-ray Timing Explorer between February and October, 1996. The source was observe…
An ASCA X-ray Observation of 1E1724-3045 in the globular cluster Terzan 2
D. Barret, J. E. Grindlay, I. M. Harrus +1
The bright persistent X-ray source and type I X-ray burster 1E1724-3045 located in the globular cluster Terzan 2 was observed by ASCA for about 10 ksec on September 24-25th, 1995 w…
CdZnTe Background Measurement at Balloon Altitudes
P. Bloser, J. Grindlay, T. Narita +1
We report results of an experiment conducted in May 1997 to measure CdZnTe background and background reduction schemes in space flight conditions similar to those of proposed hard…
Prototype Imaging Cd-Zn-Te Array Detector
P. F. Bloser, T. Narita, J. E. Grindlay +1
We describe initial results of our program to develop and test Cd-Zn-Te (CZT) detectors with a pixellated array readout. Our primary interest is in the development of relatively th…
Proposed (to) EXIST: Hard X-ray Imaging All Sky Survey/Monitor
J. E. Grindlay, T. A. Prince, F. Harrison +6
The hard x-ray (10-600 keV) sky is inherently time variable and yet has neither been surveyed nor monitored with a sensitive imaging telescope. The Energetic X-ray Imaging Survey T…
