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…
Green Bank Telescope and Swift X-ray Telescope Observations of the Galactic Center Radio Magnetar SGR J1745-2900
Ryan S. Lynch, Robert F. Archibald, Victoria M. Kaspi +1
We present results from eight months of Green Bank Telescope 8.7-GHz observations and nearly 18 months Swift X-ray telescope observations of the radio magnetar SGR J1745-2900, whic…
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…
NuSTAR observations of X-ray bursts from the magnetar 1E 1048.1-5937
Hongjun An, Victoria M. Kaspi, Andrei M. Beloborodov +13
We report the detection of eight bright X-ray bursts from the 6.5-s magnetar 1E 1048.1-5937, during a 2013 July observation campaign with the Nuclear Spectroscopic Telescope Array…
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…
NuSTAR results and future plans for magnetar and rotation-powered pulsar observations
Hongjun An, Victoria M. Kaspi, Robert Archibald +27
The Nuclear Spectroscopic Telescope Array (NuSTAR) is the first focusing hard X-ray mission in orbit and operates in the 3-79 keV range. NuSTAR's sensitivity is roughly two orders…
On the X-ray variability of magnetar 1RXS J170849.0-400910
P. Scholz, R. F. Archibald, V. M. Kaspi +4
We present a long-term X-ray flux and spectral analysis for 1RXS J170849.0-400910 using Swift/XRT spanning over 8 years from 2005-2013. We also analyze two observations from Chandr…
