The Magnetic Fields of Anomalous X-ray Pulsars
Feryal Ozel, Tolga Guver, Ersin Gogus
Anomalous X-ray Pulsars (AXPs) belong to a class of neutron stars believed to harbor the strongest magnetic fields in the universe, as indicated by their energetic bursts and their…
Physical Properties of the AXP 4U 0142+61 from X-ray Spectral Analysis
Tolga Guver, Feryal Ozel, Ersin Gogus
We analyze archival Chandra and XMM-Newton data of 4U 0142+61 within the context of the Surface Thermal Emission and Magnetospheric Scattering model. We show that 4U 0142+61 spectr…
The 2001 April Burst Activation of SGR 1900+14: Pulse Properties and Torque
P. M. Woods, C. Kouveliotou, E. Gogus +10
We report on observations of SGR 1900+14 made with the Rossi X-ray Timing Explorer (RXTE) and BeppoSAX during the April 2001 burst activation of the source. Using these data, we me…
A Comprehensive Study of Pulse Profile Evolution in SGR 1806-20 & SGR 1900+14 with the RXTE PCA
Ersin Gogus, Chryssa Kouveliotou, Peter M. Woods +2
Soft Gamma Repeaters undergo pulse profile changes in connection with their burst activity. Here we present a comprehensive pulse profile history of SGR 1806-20 and SGR 1900+14 in…
