The diffuse X-ray background spectrum from 3 to 50 keV.
The spectrum of the extragalactic diffuse X-ray background has been measured with the GSFC Cosmic X-Ray Experiment on HEAO 1 for regions of the sky away from known point sources and more than 20 /supExpand

A study of magnetic fields of accreting X-ray pulsars with the Rossi X-ray Timing Explorer
Using a consistent set of models, we parameterized the X-ray spectra of all accreting pulsars in the Rossi X-Ray Timing Explorer (RXTE) database that exhibit cyclotron resonance scattering featuresExpand

In-Flight Performance of the High Energy X-Ray Timing Experiment on the Rossi X-Ray Timing Explorer
The High Energy X-Ray Timing Experiment (HEXTE) is one of three scientific instruments aboard the Rossi X-Ray Timing Explorer (RXTE), which was launched on 1995 December 30. RXTE performs timing andExpand

Discovery of a 30. 5 day periodicity in LMC X-4
Observations covering a 500/sup d/ time span made with High-Energy X-ray and Low-Energy Gamma-Ray Instrument on HEAO 1 reveal a 30./sup d/48 +- 0./sup d/06 peroidic variability in the approx.13 toExpand

The Discovery of Rapid X-Ray Oscillations in the Tail of the SGR 1806-20 Hyperflare
We have discovered rapid quasi-periodic oscillations (QPOs) in RXTE/PCA measurements of the pulsating tail of the 2004 December 27 giant flare of SGR 1806-20. QPOs at ~92.5 Hz are detected in a 50 sExpand

Discovery of a Cyclotron Resonant Scattering Feature in the Rossi X-Ray Timing Explorer Spectrum of 4U 0352+309 (X Persei)
We have discovered a ~29 keV cyclotron resonance scattering feature (CRSF) in the X-ray spectrum of 4U 0352+309 (X Per) using observations taken with the Rossi X-Ray Timing Explorer. The source 4UExpand

The variable cyclotron line in GX 301-2
We present pulse phase resolved spectra of the hypergiant high mass X-ray binary GX 301−2. We observed the source in 2001 October with RXTE continuously for a total on-source time of almost 200 ks.Expand
