The Self-organized Criticality Behaviors of Pulses in Magnetar Bursts

The Astrophysical Journal Supplement Series
The overall temporal and spectral characteristics (e.g., duration, fluence, peak flux, peak count rate, and total counts) of X-ray bursts (XRBs) originating from magnetars have been extensively studied to confirm their self-organized criticality (SOC ...

INTEGRAL IBIS Catalog of Magnetar Bursts

The Astrophysical Journal
One of the distinctive properties of magnetars, young neutron stars powered mainly by magnetic energy, is the emission of short (≲1 s) bursts of hard X-rays. Such bursts have been observed in nearly all the known magnetars, although at different and time-

Braking index of PSR J1846−0258: a model of magnetic inclination evolution and its gravitational-wave implication

Frontiers in Astronomy and Space Sciences
We explain the braking index n=2.19±0.03 of PSR J1846−0258 by incorporating the time evolution of its magnetic inclination angle and dipolar magnetic field. Based on observational timing data and the age of the associated supernova remnant (tSNR≈1.77kyr),

Magnetic Field Effects on the Structure of Neutron Stars

Universe
We investigate the impact of ultrastrong magnetic fields on the structure of neutron stars within a density-dependent relativistic mean-field framework (DDME2).

Axion production from Landau quantization in the strong magnetic field of magnetars

Physics Letters B, 2018
We utilize an exact quantum calculation to explore axion emission from electrons and protons in the presence of the strong magnetic field of magnetars. The axion is emitted via transitions between the Landau levels generated by the strong magnetic field.

A Target Search for Fast Radio Bursts Associated with Two Fast Blue Optical Transients: AT2018cow and CSS161010

The Astrophysical Journal
Fast blue optical transients (FBOTs) are luminous, rapidly evolving events with blue spectra, possibly powered by newborn magnetars and linked to fast radio bursts (FRBs).

Instability in Supernova Fallback Disks and Its Effect on the Formation of Ultralong Period Pulsars

The Astrophysical Journal
Several pulsars with unusually long periods were discovered recently, comprising a potential population of ultralong period pulsars (ULPPs). The origin of their long periodicity is not well understood, but may be related to magnetars spun down by ...
