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

Phenomenology of the new physics coming from 2HDMs to the neutrino magnetic dipole moment
TL;DR: In this paper, the magnetic dipole moment for different flavors of neutrinos in two Higgs doublet models with and without flavor changing neutral currents has been calculated for the tau neutrino in type II and Lepton-specific cases.

Breakdown of the Goldreich–Julian relation in a neutron star
TL;DR: In this article, the magnetic field in a rotating neutron star was analyzed and the magnetic charge density was shown to exceed significantly the common Goldreich-Julian density in the presence of rotating magnetic field lines.

Hard X-ray emission cutoff in anomalous X-ray pulsar 4U 0142+61 detected by INTEGRAL
Wei Wang,Hao Tong,Yanjun Guo +2 more
TL;DR: The anomalous X-ray pulsar 4U 0142+61 was studied by the INTEGRAL observations as discussed by the authors, where the authors derived the average hard Xray spectrum of the source from 20 -- 150 keV with no significant variations (within 20$\%$) from 2003 -- 2011.

Near-infrared follow-up to the May 2008 activation of SGR 1627-41

TL;DR: In this article, the Swift satellite detected the first reactivation of SGR 1627-41 since its discovery in 1998, and an observing campaign in near infrared wavelengths was conducted to search for a possible counterpart inside the error circle of this SGR, which is expected to show flaring activity simultaneous to the high energy flares or at least some variability as compared to the quiescent state.

The Diamagnetic Phase Transition of Dense Electron Gas: Astrophysical Applications
TL;DR: In this article, the de Haas-van Alphen (dHvA) effect and the diamagnetic phase transition are associated with magnetic domain formation in the crust of a super-strong magnetar.

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.
