SXP 5.05 = IGR J00569-7226 : using X-rays to explore the structure of a Be stars circumstellar disk
M. J. Coe, E. S. Bartlett, A. J. Bird +5
On MJD 56590-1 (2013 Oct 25-26) observations of the Magellanic Clouds by the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) observatory discovered a previously-unreport…
Repeated, Delayed Torque Variations Following X-ray Flux Enhancements in the Magnetar 1E1048.15937
R. F. Archibald, V. M. Kaspi, C. -Y. Ng +4
We report on two years of flux and spin evolution monitoring of 1E 1048.15937, a 6.5-s X-ray pulsar identified as a magnetar. Using {\it Swift} XRT data, we observed an X-ray ou…
High-Resolution X-Ray Spectroscopy of the Bursting Pulsar GRO J1744-28
N. Degenaar, J. M. Miller, F. A. Harrison +3
The bursting pulsar GRO J1744-28 is a Galactic low-mass X-ray binary that distinguishes itself by displaying type-II X-ray bursts: brief, bright flashes of X-ray emission that like…
NuSTAR Observations of the Magnetar 1E 2259+586
Julia K. Vogel, Romain Hascoet, Victoria M. Kaspi +15
We report on new broad band spectral and temporal observations of the magnetar 1E 2259+586, which is located in the supernova remnant CTB 109. Our data were obtained simultaneously…
The peculiar Galactic center neutron star X-ray binary XMM J174457-2850.3
N. Degenaar, R. Wijnands, M. T. Reynolds +6
The recent discovery of a milli-second radio pulsar experiencing an accretion outburst similar to those seen in low mass X-ray binaries, has opened up a new opportunity to investig…
Timing and Flux Evolution of the Galactic Center Magnetar SGR J1745-2900
V. M. Kaspi, R. F. Archibald, V. Bhalerao +19
We present the X-ray timing and spectral evolution of the Galactic Center magnetar SGR J1745-2900 for the first ~4 months post-discovery using data obtained with the Nuclear Spectr…
