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

TL;DR: In this paper, the authors presented the analyses of the Burst Alert Telescope (BAT)detected GRBs for the past ~ 11 years up through GRB151027B, and performed searches for GRB emissions before or after the event data using the BAT survey data, and estimated the false detection rate to be only one false detection in this sample.

Lifting shell structures in the dynamically assisted Schwinger effect in periodic fields
A. Otto,A. Otto,Daniel Seipt,David Blaschke,Burkhard Kampfer,Burkhard Kampfer,Stanislav A. Smolyansky +6 more
TL;DR: In this article, the Schwinger effect is considered for the superposition of two periodic electric fields acting in a finite time interval, and a strong enhancement by orders of magnitude caused by a weak field with a frequency being a multitude of the strong field frequency is found.

The fundamental plane for radio magnetars
TL;DR: In this paper, it was shown that radio emission from magnetars might be powered by rotational energy, similarly to what occurs in normal radio pulsars, and that magnetar radio activity or inactivity can be predicted from the knowledge of the star's rotational period, its time derivative and the quiescent X-ray luminosity.

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.
