Emission from neutron stars with condensed surface: a systematic analysis [PDF]

, 2023
openAmongst the various classes of neutron stars, magnetars are the ones hosting the strongest magnetic fields. The study of their emission in the X-ray band allows to achieve unprecedented knowledge of the physical processes in the presence of ultra ...

Low-energy Radio Bursts from Magnetar XTE J1810−197: Implications for Fast Radio Bursts

The Astrophysical Journal
Magnetars are the leading candidate sources of fast radio bursts (FRBs). However, the observational probes of the connections between magnetars and FRBs are severely limited by the paucity of detection of highly energetic radio events from magnetars—to ...

Deep Searches for Radio Pulsations and Bursts from Four Magnetar and a Magnetar-like Pulsar with FAST

The Astrophysical Journal
We report on radio observations of four magnetars SGR 0501+4516, Swift 1834.9–0846, 1E 1841–045, SGR 1900+14, and a magnetar-like pulsar PSR J1846–0258 with the Five-hundred-meter Aperture Spherical radio Telescope at 1250 MHz.

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).

Magnetic fields generated by r-modes in accreting millisecond pulsars [PDF]

, 2010
In rotating neutron stars the existence of the Coriolis force allows the presence of the so-called Rossby oscillations (r-modes) which are known to be unstable to emission of gravitational waves.

On the Nature of Magnetars [PDF]

Symposium - International Astronomical Union, 2004
The electromagnetic fields of magnetodipole radiation can penetrate to the conducting matter of a neutron star crust and create there electric currents and tangential magnetic fields of high magnitude. The solution obtained here has the form of surface magnetic field discontinuities propagating through the crust to the core.

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.

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

Gravitational-wave Radiation from the Magnetar-driven Supernovae

The 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

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.
