Magnetars and pulsars: a missing link [PDF]
, 2002 There is growing evidence that soft gamma-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are isolated neutron stars with superstrong magnetic fields, i.e., magnetars, marking them a distinguished species from the conventional species of spindown-

The strongest magnetic fields in the universe: How strong can they become?
Frontiers in Physics, 2014 Magnetic fields in the universe are in general weak, of the order of µGauss only. However, in compact objects they assume extraordinarily large values. These are produced by gravitational collapse of massive magnetised objects.

“Slow” Radio Bursts from Galactic Magnetars? [PDF]
, 2020 Recently, one fast radio burst (FRB), FRB 200428, was detected from the Galactic magnetar soft gamma-ray repeater (SGR) J1935+2154 during one X-ray burst. This suggests that magnetars can make FRBs.

Magnetic Reconnection in the Space Sciences: Past, Present, and Future
Journal of Geophysical Research: Space Physics, Volume 125, Issue 2, February 2020., 2020 Abstract Magnetic reconnection converts, often explosively, stored magnetic energy to particle energy in space and in the laboratory. Through processes operating on length scales that are tiny, it facilitates energy conversion over dimensions of, in some cases, hundreds of Earth radii.

Interpreting the X-ray afterglows of gamma-ray bursts with radiative losses and millisecond magnetars [PDF]
, 2020 The spin-down energy of millisecond magnetars has been invoked to explain X-ray afterglow observations of a significant fraction of short and long gamma-ray bursts.

Pair Plasma in Super-QED Magnetic Fields and the Hard X-Ray/Optical Emission of Magnetars [PDF]
Astrophysical Journal, 2020 The photon spectrum emitted by a transrelativistic pair plasma is calculated in the presence of an ultrastrong magnetic field, and is shown to bear a remarkable resemblance to the rising hard X-ray spectra of quiescent magnetars. This emission is powered

Zeeman Splitting of Torsional Oscillation Frequencies of Magnetars
Universe, 2023 Magnetars form a special class of neutron stars possessing superstrong magnetic fields and demonstrating power flares triggered by these fields. Observations of such flares reveal the presence of quasi-periodic oscillations (QPOs) at certain frequencies;

Wind braking of magnetars: to understand magnetar's multiwave radiation properties
, 2014 Magnetars are proposed to be peculiar neutron stars powered by their super strong magnetic field. Observationally, anomalous X-ray pulsars and soft gamma-ray repeaters are believed to be magnetar candidates.

Gravitational Radiation from Newborn Magnetars [PDF]
, 2005 There is growing evidence that two classes of high-energy sources, the Soft Gamma Repeaters and the Anomalous X-ray Pulsars contain slowly spinning ``magnetars'', i.e.

Monthly notices of the Royal Astronomical Society, 2019 We consider the current observed ensemble of pulsing ultraluminous X-ray sources (PULXs). We show that all of their observed properties (luminosity, spin period, and spin-up rate) are consistent with emission from magnetic neutron stars with fields in ...
