Observations of Radio Magnetars with the Deep Space Network [PDF]
Advances in Astronomy, 2019 The Deep Space Network (DSN) is a worldwide array of radio telescopes which supports NASA’s interplanetary spacecraft missions. When the DSN antennas are not communicating with spacecraft, they provide a valuable resource for performing observations of ...

Multipolar Electromagnetic Emission of Newborn Magnetars [PDF]
The Astrophysical JournalIt is generally recognized that the electromagnetic multipolar emission from magnetars can be used to explain radiation from soft gamma repeaters or anomalous X-ray pulsars, but they have little impact on the spin-down of magnetars.

Axion-mediated Transport of Fast Radio Bursts Originating in Inner Magnetospheres of Magnetars [PDF]
Astrophysical Journal Letters, 2023 Among magnetar models of fast radio bursts (FRBs), there is ongoing debate about whether the site of coherent radio emission lies within or beyond the light cylinder. We propose a mechanism by which FRBs produced near the magnetar surface are transported

Deflection of light by magnetars in the generalized Born–Infeld electrodynamics [PDF]
The European Physical Journal C, 2022 We study the deflection of light by a magnetic dipole field in the generalized Born–Infeld electrodynamics. Using the effective index of refraction and the trajectory equation based on geometric optics, we compute the weak bending angle of light passing ...

Evidence for an abundant old population of Galactic ultra long period magnetars and implications for fast radio bursts [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Two recent discoveries, namely PSR J0901-4046 and GLEAM-X J162759.5-523504.3 (hereafter GLEAM-X J1627), have corroborated an extant population of radio-loud periodic sources with long periods (76 s and 1091 s respectively) whose emission can hardly be ...

High-energy Photon Opacity in the Twisted Magnetospheres of Magnetars [PDF]
Astrophysical Journal, 2022 Magnetars are neutron stars characterized by strong surface magnetic fields generally exceeding the quantum critical value of 44.1 TG. High-energy photons propagating in their magnetospheres can be attenuated by QED processes like photon splitting and ...

Precession of magnetars: dynamical evolutions and modulations on polarized electromagnetic waves [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Magnetars are conjectured to be highly magnetized neutron stars (NSs). Strong internal magnetic field and elasticity in the crust may deform the stars and lead to free precession.

Magnetars and axion-like particles: probes with the hard X-ray spectrum [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Quiescent hard X-ray and soft gamma-ray emission from neutron stars constitute a promising frontier to explore axion-like-particles (ALPs). ALP production in the core peaks at energies of a few keV to a few hundreds of keV; subsequently, the ALPs escape ...
