Discovery of Hard Nonthermal Pulsed X-Ray Emission from the Anomalous X-Ray Pulsar 1E 1841-045
We report the discovery of nonthermal pulsed X-ray/soft gamma-ray emission up to ~150 keV from the anomalous 11.8 s X-ray pulsar AXP 1E 1841-045 located near the center of supernova remnant Kes 73
X-Ray Timing, Spectroscopy and Photometry of the Anomalous X-Ray Pulsar Candidate CXOU J010043.1-721134
We present new X-ray timing and spectral results on the 8.0 s X-ray pulsar CXOU J010043.1-721134 from a series of observations using the Chandra X-Ray Observatory. We found a spin period in 2004
Variation of Spectral and Timing Properties in the Extended Burst Tails from the Magnetar 4U 0142+61
Extended emission episodes with intensity above the pre-burst level are observed following magnetar bursts from a number of soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs). Such
THE DISCOVERY OF A PULSAR WIND NEBULA AROUND THE MAGNETAR CANDIDATE AXP 1E1547.0-5408
We report the detection of extended emission around the anomalous X-ray pulsar 1E1547.0-5408 using archival data of the Chandra X-ray satellite. The extended emission consists of an inner part, with
The dynamic behavior of soft gamma repeaters
Giant Flare of SGR 1806-20 from a Relativistic Jet
Japanese magnetospheric explorer GEOTAIL recorded a detailed light curve during the initial 600 msec of a giant flare from SGR 1806-20 on December 27, 2004. We show that the observed light curve is
The Zoo of Neutron Stars
In these lecture notes, I briefly discuss the present day situation and new discoveries in astrophysics of neutron stars focusing on isolated objects. The latter include soft gamma repeaters,
On Hoyle-Narlikar-Wheeler mechanism of vibration energy powered magneto-dipole emission of neutron stars
We revisit the well-known Hoyle-Narlikar-Wheeler proposition that neutron star emerging in the magnetic-flux-conserving process of core-collapse supernova can convert the stored energy of Alfvén
Vibration-Powered Radiation of Quaking Magnetar
In juxtaposition with the standard model of rotation-powered pulsar, the model of vibration-powered magnetar undergoing quake-induced torsional Alfven vibrations in its own ultrastrong magnetic field
ISOLATED NEUTRON STARS: AN ASTROPHYSICAL PERSPECTIVE
We briefly review selected results in astrophysics of neutron stars (NSs) obtained during the last two years, focusing on isolated radioquiet objects. We discuss in some details population synthesis

Long-Term Rossi X-Ray Timing Explorer Monitoring of the Anomalous X-Ray Pulsar 1E 1048.1–5937
We report on long-term monitoring of the anomalous X-ray pulsar (AXP) 1E 1048.1-5937 using the Rossi X-Ray Timing Explorer (RXTE). The timing behavior of this pulsar is different from that of other
A Major Soft Gamma Repeater-like Outburst and Rotation Glitch in the No-longer-so-anomalous X-Ray Pulsar 1E 2259+586
We report a major outburst from the anomalous X-ray pulsar 1E 2259+586, in which over 80 X-ray bursts were detected in 4 hr using the Rossi X-Ray Timing Explorer. The bursts range in duration from 2
Precision Timing of Two Anomalous X-Ray Pulsars.
TLDR
The frequency derivative for 1E 2259+586 is inconsistent with that inferred from incoherent frequency observations made over the last 20 yr, consistent with the magnetar hypothesis and make binary accretion scenarios appear unlikely.
Magnetar-like X-ray bursts from an anomalous X-ray pulsar
TLDR
Two X-ray bursts, with properties similar to those of SGRs, from the direction of the anomalousX-ray pulsar 1E1048.1 - 5937.1 imply a close relationship (perhaps evolutionary) between AXPs and S GRs, with both being magnetars.
Differences between the two anomalous X‐ray pulsars: variations in the spin‐down rate of 1E 1048.1−5937 and an extended interval of quiet spin‐down in 1E 2259+586
We analysed the Rossi X-ray Timing Explorer (RXTE) archival data of 1E 1048.1-5937 covering a time-span of more than one year. The spin-down rate of this source decreases by similar to 30 per cent
A Glitch in an Anomalous X-ray Pulsar
We report the detection of a sudden spin-up of the 11 s anomalous X-ray pulsar 1RXS J170849.0-400910 in regular timing observations made with the Rossi X-Ray Timing Explorer. The event, which
Study of the Long Term Stability of two Anomalous X-ray Pulsars 4U 0142+61 and 1E 1048.1-5937 with ASCA
We present new observations of two anomalous X-ray pulsars (AXPs), 4U 0142+61 and 1E 1048.1-5937, made in 1998 with ASCA. The energy spectrum of each of these two AXPs is found to consist of two
The anomalous X-ray pulsar 1E 1048.1-5937: Phase resolved spectroscopy with the XMM-Newton satellite
We report on an observation of the anomalous X–ray pulsar 1E 1048.1–5937 performed with the XMM-Newton satellite. The phase averaged spectrum of 1E 1048.1–5937 is well described by the sum of a power
Optical pulsations from the anomalous X-ray pulsar 4U0142+61
TLDR
The pulsed fraction of optical light is five to ten times greater than that of soft X-rays, from which it is concluded that 4U0142+61 is a magnetar, which establishes a direct relationship between AXPs and the soft γ-ray repeaters, the evolutionary connection betweenAXPs, SGRs and radio pulsars remains controversial.
The Quiescent Counterpart of the Soft Gamma-Ray Repeater SGR 0526–66
It is now commonly believed that soft gamma-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are magnetars—neutron stars powered by their magnetic fields. However, what differentiates these
