RXTE Discovery of Coherent Millisecond Pulsations during an X-ray Burst from KS 1731-260
Donald A. Smith, Edward H. Morgan, Hale Bradt
A highly coherent 523.92+-0.05 Hz periodic X-ray signal has been observed during a type I X-ray burst from the low-mass X-ray binary system KS 1731-260 with the PCA on RXTE. The sp…
The Weak Blue Bump of H2106-099 and AGN De-Reddening
B. Grossan, R. A. Remillard, H. V. Bradt +3
We present multi-frequency spectra of the Seyfert 1 galaxy H2106-099, from radio to hard X-rays, spanning over a decade of observations. The hard X-ray (2-20 keV) spectrum measured…
First Results from the All-Sky Monitor on the Rossi X-ray Timing Explorer
Alan M. Levine, Hale Bradt, Wei Cui +5
The All-Sky Monitor on the Rossi X-ray Timing Explorer has been monitoring the sky in the 1.5 - 12 keV band since late February. The instrument consists of three coded-aperture cam…
