Search for Near-Infrared Pulsation of the Anomalous X-ray Pulsar 4U 0142+61
Mikio Morii, Naoto Kobayashi, Nobuyuki Kawai +4
We have searched for pulsation of the anomalous X-ray pulsar (AXP) 4U 0142+61 in the K' band ( m) using the fast-readout mode of IRCS at the Subaru 8.2-m tel…
Suzaku Observation of AXP 1E 1841-045 in SNR Kes 73
M. Morii, S. Kitamoto, N. Shibazaki +7
Anomalous X-ray pulsars (AXPs) are thought to be magnetars, which are neutron stars with ultra strong magnetic field of -- G. Their energy spectra below 10…
Suzaku Observation of the Anomalous X-ray Pulsar CXOU J164710.2--455216
Sachindra Naik, Tadayasu Dotani, Nobuyuki Kawai +11
Suzaku TOO observation of the anomalous X-ray pulsar CXOU J164710.2-455216 was performed on 2006 September 23--24 for a net exposure of 38.8 ks. During the observation, the XIS was…
Detection of a Rare Supersoft Outburst Event during a Suzaku Observation of 1E0102.2-7219
D. Takei, M. Tsujimoto, S. Kitamoto +4
We report the detection of a transient X-ray source toward the Small Magellanic Cloud (SMC) using the X-ray Imaging Spectrometer (XIS) onboard the Suzaku telescope. The source was…
Pulse Profile Change Possibly Associated with a Glitch in an Anomalous X-Ray Pulsar 4U 0142+61
Mikio Morii, Nobuyuki Kawai, Noriaki Shibazaki
We report a glitch-like pulse frequency deviation from the simple spin-down law in an anomalous X-ray pulsar (AXP) 4U 0142+61 detected by ASCA observations. We also found a signifi…
Chandra Observation of the Anomalous X-ray Pulsar 1E 1841-045
Mikio Morii, Rie Sato, Jun Kataoka +1
We present the results from the {\it Chandra} ACIS CC mode observation of an anomalous X-ray pulsar (AXP) 1E 1841-045. This is the first observation in which the pulsar spectrum in…
