Extragalactic Magnetism with SOFIA (SALSA Legacy Program). V. First Results on the Magnetic Field Orientation of Galaxies

open access: yesThe Astrophysical Journal, 2023
We present the analysis of the magnetic field ( B -field) structure of galaxies measured with far-infrared (FIR) and radio (3 and 6 cm) polarimetric observations.

The high energy X-ray probe (HEX-P): a new window into neutron star accretion

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Accreting neutron stars (NSs) represent a unique laboratory for probing the physics of accretion in the presence of strong magnetic fields (B ≳ 108 G).

Evidence for Strong Extragalactic Magnetic Fields from Fermi Observations of TeV Blazars [PDF]

open access: yesScience, 2010
On the Origins of Magnetism The magnetic fields in galaxies and galaxy clusters are thought to result from the amplification of weak primordial magnetic fields, which, according to one class of theories, should exist in the voids between galaxies and galaxy clusters. Neronov and Vovk (p. 73

The Large-scale Anisotropy and Flux (de)magnification of Ultrahigh-energy Cosmic Rays in the Galactic Magnetic Field

open access: yesThe Astrophysical Journal Letters
We calculate the arrival direction distribution of ultrahigh-energy cosmic rays (UHECRs) with a new suite of models of the Galactic magnetic field (GMF), assuming sources follow the large-scale structure of the Universe.

The origin of intergalactic magnetic fields due to extragalactic jets [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1992
The large-scale magnetization of intra- and intercluster media due to electric current-carrying extragalactic jets generated by active periods of galactic nuclei is studied. The Lorentz force acting on the return current path has an expansive character which is responsible for the generation of a growing magnetic cocoon surrounding the associated jet ...

Toward Cosmological Simulations of the Magnetized Intracluster Medium with Resolved Coulomb Collision Scale

open access: yesThe Astrophysical Journal
We present the first results of one extremely high-resolution, nonradiative magnetohydrodynamical cosmological zoom-in simulation of a massive cluster with a virial mass of  M _vir = 2.0 × 10 ^15 solar masses. We adopt a mass resolution of 4 × 10 ^5 M _⊙
