Magnetars in Binaries as the Engine of Actively Repeating Fast Radio Bursts

The Astrophysical Journal Letters
The association between FRB 20200428D and the Galactic magnetar SGR J1935+2154 makes magnetars the leading engine of cosmological fast radio bursts (FRBs).

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

Galaxies
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

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

Journal 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.

Magnetic Domains in Magnetar Matter as an Engine for Soft Gamma-ray Repeaters and Anomalous X-ray Pulsars

, 2010
Magnetars have been suggested as the most promising site for the origin of observed soft gamma-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs). In this work we investigate the possibility that SGRs and AXPs might be observational evidence for a ...

The Galactic Population of Magnetars: A Simulation-based Inference Study

The Astrophysical Journal
Population synthesis modeling of the observed dynamical and physical properties of a population is a highly effective method for constraining the underlying birth parameters and evolutionary tracks.

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

Frontiers 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

Ultrahigh energy cosmic ray acceleration in newly born magnetars and their associated gravitational wave signatures

, 2011
Newly born magnetars are good candidate sources of ultrahigh energy cosmic rays. These objects can in principle easily accelerate particles to the highest energies required to satisfy the ultrahigh energy cosmic ray scenario (E~10^{20-21} eV), thanks to ...

The Magnetar SGR 1935+2154’s Quiet Local Environment: Clues for Its Progenitor

The Astrophysical Journal
Magnetars are highly magnetized neutron stars whose evolution and radiation are governed by the decay and/or reconfiguration of their magnetic fields.

IXPE Observations of Magnetar Sources

Galaxies
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

The Magnetar Connection

Proceedings of the International Astronomical Union, 2020
AbstractWe investigate the combined evolution of the dipolar surface magnetic field (Bs) and the spin-period (Ps) of known Magnetars and high magnetic field ( $${{\rm{B}}_s} \mathbin{\lower.3ex\hbox{$\buildrel>\over {\smash{\scriptstyle\sim}\vphantom{_x}}$}} {10^{13}}{\rm{G}}$$ ) radio pulsars.
