The strongest cosmic magnets: soft gamma-ray repeaters and anomalous X-ray pulsars
Abstract:
Two classes of X-ray pulsars, the anomalous X-ray pulsars and the soft gamma-ray repeaters, have been recognized in the last decade as the most promising candidates for being magnetars: isolated neutron stars powered by magnetic energy. I review the observational properties of these objects, focussing on the most recent results, and their interpretation in the magnetar model. Alternative explanations, in particular those based on accretion from residual disks, are also considered. The possible relations between these sources and other classes of neutron stars and astrophysical objects are also discussed.read more

Non-detection in a Fermi/LAT observation of AXP 4U 0142+61: magnetars?
Hao Tong,L. M. Song,Renxin Xu +2 more
TL;DR: In this paper, the authors proposed that Fermi/LAT observations may distinguish between the magnetar model and the accretion model for anomalous X-ray pulsars and soft gamma-ray repeaters (SGRs).

Long-term radiative behavior of sgr 1900+14
TL;DR: In this paper, the authors used archival Chandra and XMM-Newton observations of SGR 1900+14 to construct a history of its spectrum and persistent X-ray flux spanning a period of about seven years.

TL;DR: The New Hard X-ray Mission (NHXM) as discussed by the authors is a mission that combines high-sensitivity, hard-X-ray imaging, broadband spectroscopy and polarimetry.

Antiglitch Inconsistent With Magnetar Model of AXP
TL;DR: The recently observed antiglitch of AXP 1E 2259+586 is inconsistent with magnetar models, but may be explained as the consequence of sudden accretion of retrograde matter or "propeller" interaction with surrounding matter as mentioned in this paper.

Formation of very strongly magnetized neutron stars - Implications for gamma-ray bursts
TL;DR: In this article, it is argued that a convective dynamo can also generate a very strong dipole field after the merger of a neutron star binary, but only if the merged star survives for as long as about 10-100 ms.

The Soft Gamma Repeaters as Very Strongly Magnetized Neutron Stars. II. Quiescent Neutrino, X-Ray, and Alfvén Wave Emission
TL;DR: In this article, the decay rate of the core field is a very strong function of temperature and therefore of the magnetic flux density, which is not present in the decay of the weaker fields associated with ordinary radio pulsars.

TL;DR: In this paper, the authors reported the discovery of pulsations in the persistent X-ray flux of SGR1806-20, with a period of 7.47 s and a spindown rate of 2.6 x 10(exp -3) s/yr.
