Impact of the ISM magnetic field on GRB afterglow polarization [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Linear polarization has been measured in several gamma-ray burst (GRB) afterglows. After a few days, polarization arises from the forward shock emission that depends on the post-shock magnetic field. The latter can originate both from compression of existing fields, here the interstellar medium (ISM) magnetic field, and from ...

The supernova-regulated ISM – II. The mean magnetic field [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2012 Abstract The origin and structure of the magnetic fields in the interstellar medium of spiral galaxies is investigated with 3D, non-ideal, compressible magnetohydrodynamic simulations, including stratification in the galactic gravity field, differential rotation and radiative cooling.

MHD Simulations of the ISM: The Importance of the Galactic Magnetic Field on the ISM “Phases” [PDF]
Astrophysics and Space Science, 2004 We have carried out 1.25 pc resolution MHD simulations of the ISM, on a Cartesian grid of $0 \leq (x,y) \leq 1$ kpc size in the galactic plane and $-10 \leq z \leq 10$ kpc into the halo, thus being able to fully trace the time-dependent evolution of the galactic fountain. The simulations show that large scale gas streams emerge, driven by SN explosions,

The role of the random magnetic fields in the ISM: HVC numerical simulations [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractWe know that the galactic magnetic field possesses a random component in addition to the mean uniform component, with comparable strength of the two components. This random component is considered to play important roles in the evolution of the interstellar medium (ISM).

Relative distributions of cosmic ray electrons and magnetic fields in the ISM [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractWe calculate the relative magnitudes of the fluctuations in total synchrotron intensity in the interstellar medium, both from observations and from theory under various assumptions about the correlation or anticorrelation between cosmic rays and interstellar magnetic fields.

The interaction of the planetary nebula NGC 6894 with the ISM magnetic field [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 We have obtained images of the planetary nebula NGC 6894 and the 'stripes' near it and have analysed their morphologies. Our analysis suggests that the material of the stripes has been ionized by the central star of NGC 6894, and could have originated from the stripping of the halo of NGC 6894 by the interstellar medium (ISM).

Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT The physics of magnetic fields (B) and cosmic rays (CRs) have recently been included in simulations of galaxy formation. However, significant uncertainties remain in how these components affect galaxy evolution. To understand their common observational tracers, we analyse the magnetic fields in a set of high-resolution ...
