X-ray Polarization from Magnetar Sources
GalaxiesThe launch of the IXPE telescope in late 2021 finally made polarization measurements in the 2–8keV band a reality, more than 40 years after the pioneering observations of the OSO-8 satellite.

Role of Time‐Varying Magnetic Field on QGP Equation of State
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.The phase diagram of quantum chromodynamics (QCD) and its associated thermodynamic properties of quark‐gluon plasma (QGP) are studied in the presence of time‐dependent magnetic field. The study plays a pivotal role in the field of cosmology, astrophysics, and heavy‐ion collisions. In order to explore the structure of quark‐gluon plasma to deal with the

Ambipolar Heating of Magnetars
The Astrophysical Journal, 2023 Magnetars, neutron stars thought to be with ultrastrong magnetic fields of 10 ^14–15 G, are observed to be much hotter than ordinary pulsars with ∼10 ^12 G, and additional heating sources are required.

Search for high-energy neutrinos from magnetars with IceCube
, 2022 Magnetars are neutron stars with very strong magnetic fields on the order of 1013 to 1015 G. Young magnetars (< 104 years) with oppositely-oriented magnetic fields and spin moments may emit high-energy (HE) neutrinos from their polar caps as they may be ...

Pulsed γ-ray emission from magnetar 1E 2259+586 [PDF]
Journal of Astronomy and Space Sciences, 2013 Anomalous X-ray pulsars (AXPs) are thought to be magnetars which are young isolated neutron stars with extremely strong magnetic fields of >1014 Gauss.

Magnetars: general properties and recent developments
, 2011 Magnetars, which form a growing subgroup of neutron stars, possess the strongest magnetic field environments in the universe. The last few years has been very fruitful for magnetars: three new sources were discovered and one source was correctly ...

Magnetars: the physics behind observations. A review [PDF]
, 2015 Magnetars are the strongest magnets in the present universe and the combination of extreme magnetic field, gravity and density makes them unique laboratories to probe current physical theories (from quantum electrodynamics to general relativity) in the ...

The Astrophysical Journal, 2007 We develop a theoretical model that explains the formation of hot coronae around strongly magnetized neutron stars -- magnetars. The starquakes of a magnetar shear its external magnetic field, which becomes non-potential and is threaded by an electric current. Once twisted, the magnetosphere cannot untwist immediately because of its self-induction. The

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.

, 2021 Two classes of X-ray/$γ$-ray sources, the Soft Gamma Repeaters and the Anomalous X-ray Pulsars have been identified with isolated, slowly spinning magnetars, neutron stars whose emission draws energy from their extremely strong magnetic field ($\sim 10^{15}-10^{16}$ G).
