HEXTE Studies of Sco X-1 Spectra: Detections of Hard X-Ray Tails Beyond 200 keV

Autor: D'Amico, F., Heindl, W. A., Rothschild, R. E., Peterson, L. E., Gruber, D. E., Pelling, M., Tomsick, J. A.

Using the HEXTE experiment on-board the RXTE satellite, we performed a search for hard X-ray tails in Sco X-1 spectra. We found strong evidence for the presence of such a non-thermal component on several occasions. Using the PCA/RXTE we were able to

The Spectrum of Diffuse Cosmic Hard X-Rays Measured with HEAO-1

Autor: Gruber, D. E., Matteson, J. L., Peterson, L. E., Jung, G. V.

The spectrum of the diffuse isotropic component of cosmic X-rays over the 13-180 keV range was determined by the UCSD/MIT Hard X-Ray and Gamma-Ray instrument (HEAO A4) on the High Energy Astronomical Observatory-1 (HEAO-1). The instrument consists of

The X-ray Spectrum of the Plerionic System PSR B1509-58/MSH 15-52

Autor: Marsden, D., Blanco, P. R., Gruber, D. E., Heindl, W. A., Pelling, M. R., Peterson, L. E., Rothschild, R. E., Rots, A. H., Jahoda, K., Macomb, D. J.

We present the results of observations of the PSR B1509$-$58/MSH 15$-$52 system in X-rays ($2-250$ keV) by the Rossi X-ray Timing Explorer. The spectra of the peak of the pulsed component (radio phase $0.17-0.53$) is fit by a power law of photon inde
