Gravitational-wave Radiation from the Magnetar-driven Supernovae

open access: yesThe Astrophysical Journal
Rapidly spinning magnetars are potential candidates for the energy source of supernovae (SNe) and gamma-ray bursts and the most promising sources for continuous gravitational waves (GWs) detected by ground-based GW detectors.

X-ray Data Analysis to Search for Magnetar Candidates in the Galactic Plane

open access: yesJournal of Astronomy and Space Sciences, 2018
We report on our Galactic plane searches for magnetars in the archival Chandra X-ray Observatory (CXO) data. We summarize the properties of known magnetars and use them to establish a procedure for magnetar searches.

The high energy X-ray probe (HEX-P): magnetars and other isolated neutron stars

open access: yesFrontiers in Astronomy and Space Sciences
The hard X-ray emission from magnetars and other isolated neutron stars remains under-explored. An instrument with higher sensitivity to hard X-rays is critical to understanding the physics of neutron star magnetospheres and also the relationship between

The state of magnetars [PDF]

open access: yesProceedings of 11th INTEGRAL Conference Gamma-Ray Astrophysics in Multi-Wavelength Perspective — PoS(INTEGRAL2016), 2017
We have witnessed a remarkable advancement in the field of magnetars, neutron stars with extremely strong magnetic fields in recent years. The number of magnetar systems has tripled in less than a decade, and almost all known sources exhibited extraordinary observational characteristics, such as extremely energetic giant flares, various timing ...

The Self-organized Criticality Behaviors of Pulses in Magnetar Bursts

open access: yesThe 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 ...

Late-Time Radio Diagnostics of Magnetar Magnetic Burial and Reemergence in GRB Afterglows

open access: yesGalaxies
Recent centimeter-to-millimeter monitoring of nearby gamma-ray bursts (GRBs) has revealed late-time (≳102–104 days) radio rebrightenings and spectral turnovers not explained by standard forward-shock scenarios with steady microphysics. We attribute these

INTEGRAL IBIS Catalog of Magnetar Bursts

open access: yesThe 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-

Magnetic Field Effects on the Structure of Neutron Stars

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

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

open access: yesThe 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 ...

IXPE Observations of Magnetar Sources

open access: yesGalaxies
Among the more than 60 sources observed in the first two years of operations, IXPE addressed four magnetars, neutron stars believed to host ultra-strong magnetic fields. We report here the main implication coming from IXPE measurements for the physics of
