Long-term Periodicities in the Flux from Low Mass X-ray Binaries (2005)
Dieters, Stefan, O'Neill, Paul, Farrell, Sean, Sood, Ravi
Using data from the All Sky Monitor (ASM) on the Rossi X-ray Timing Explorer (RXTE) we have searched for long term periodicities in the X-ray flux of GX 1+4, Sco X-2 (GX 349+2), and GX 339-4. For GX...

The Soft Gamma Repeater SGR 1900+14 entered a remarkable phase of activity during the summer of 1998. This activity peaked on August 27, 1998 when a giant periodic gamma-ray flare resembling the...
Timing Noise in SGR 1806-20 (2000)
Woods, Peter M., Kouveliotou, Chryssa, Finger, Mark H., Gogus, Ersin, Scott, D. Matthew, Dieters, Stefan, ...
We have phase connected a sequence of RXTE PCA observations of SGR 1806-20 covering 178 days. We find a simple secular spin-down model does not adequately fit the data. The period derivative varies...
Discovery of a New Soft Gamma Repeater, SGR 1627-41 (1999)
Woods, Peter M., Kouveliotou, Chryssa, Van Paradijs, Jan, Hurley, Kevin, Kippen, R. Marc, Finger, Mark H., ...
We report the discovery of a new soft gamma repeater (SGR), SGR 1627-41, and present BATSE observations of the burst emission and BeppoSAX NFI observations of the probable persistent X-ray...
Discovery of a magnetar associated with the Soft Gamma Repeater SGR 1900+14 (1998)
Kouveliotou, Chryssa, Strohmayer, Tod, Hurley, Kevin, Van Paradijs, Jan, Finger, Mark H., Dieters, Stefan, ...
The soft-gamma repeater SGR 1900+14 became active again on June 1998 after a long period of quiescence; it remained at a low state of activity until August 1998, when it emitted a series of...
RXTE Observations of the Anomalous Pulsar 4U 0142+61 (1998)
Wilson, Colleen A., Dieters, Stefan, Finger, Mark H., Scott, D. Matthew, Van Paradijs, Jan
We observed the anomalous X-ray pulsar 4U 0142+61 using the Proportional Counter Array (PCA) aboard the Rossi X-ray Timing Explorer (RXTE) in March 1996. The pulse frequency was measured as f =...
