Deviations from the Flux-Recurrence Time Relationship in GS 1826-238: Potential Transient Spectral Changes
Thomas W. J. Thompson, Duncan K. Galloway, Richard E. Rothschild +1
The low-mass X-ray binary GS 1826-238 is presently unique for its consistently regular bursting behavior. In previous Rossi X-Ray Timing Explorer (RXTE) measurements between 1997 N…
The Variable Warm Absorber in Circinus X-1
N. S. Schulz, T. E. Kallman, D. K. Galloway +1
We observed Circinus X-1 twice during a newly reached low-flux phase near zero orbital phase using the High-Energy Transmission Grating Spectrometer (HETGS) onboard Chandra. In bot…
Discovery of the accretion-powered millisecond pulsar SWIFT J1756.9-2508 with a low-mass companion
H. A. Krimm, C. B. Markwardt, C. J. Deloye +10
We report on the discovery by the Swift Gamma-Ray Burst Explorer of the eighth known transient accretion-powered millisecond pulsar, SWIFT J1756.9-2508, as part of routine observat…
Evidence for a parsec scale X-ray jet from the accreting neutron star Circinus X-1
S. Heinz, N. S. Schulz, W. N. Brandt +1
We analyzed the zero-order image of a 50 ks Chandra gratings observation of Circinus X-1, taken in 2005 during the source's low-flux state. Circinus X-1 is an accreting neutron sta…
Compton Scattering of Fe K alpha Lines in Magnetic Cataclysmic Variables
A. L. McNamara, Z. Kuncic, K. Wu +2
Compton scattering of X-rays in the bulk flow of the accretion column in magnetic cataclysmic variables (mCVs) can significantly shift photon energies. We present Monte Carlo simul…
Intermittent pulsations in an accretion-powered millisecond pulsar
Duncan K. Galloway, Edward H. Morgan, Miriam I. Krauss +2
We describe observations of the seventh accretion-powered millisecond pulsar, HETE J1900.1-2455 made with the Rossi X-ray Timing Explorer during the year of activity that followed…
