Cosmic Rays in Clusters of Galaxies [PDF]

open access: yes, 2002
We argue that clusters of galaxies have an intergalactic medium, which is permeated by strong magnetic fields and also has a contribution of pressure from cosmic rays.

B-fields and Dust in Interstellar Filaments Using Dust Polarization (BALLAD-POL). III. Grain Alignment and Disruption Mechanisms in G34.43+0.24 Using Polarization Observations from JCMT/POL-2

open access: yesThe Astrophysical Journal
Polarization of starlight and thermal dust emission due to aligned non-spherical grains helps us to trace magnetic field ( B -field) morphology in molecular clouds and to study grain alignment mechanisms.

A New Constraint on the Relative Disorder of Magnetic Fields between Neutral Interstellar Medium Phases

open access: yesThe Astrophysical Journal
Utilizing Planck polarized dust emission maps at 353 GHz and large-area maps of the neutral hydrogen (H i ) cold neutral medium (CNM) fraction ( f _CNM ), we investigate the relationship between dust polarization fraction ( p _353 ) and f _CNM in the ...

B-fields and Dust in Interstellar Filaments Using Dust Polarization (BALLAD-POL). IV. Grain Alignment Mechanisms in the Cocoon Nebula (IC 5146) Using Polarization Observations from JCMT/POL-2

open access: yesThe Astrophysical Journal
The polarization of starlight and thermal dust emission from aligned nonspherical grains provides a powerful tool for tracing magnetic field morphologies and strengths in the diffuse interstellar medium to star-forming regions, and constraining the ...

Research in particles and fields [PDF]

open access: yes
Investigations, by particle-detectors flown on spacecraft, of the astrophysical aspects of cosmic radiation and the radiation environment of the earth are reported along with the research of the interplanetary medium, and planetary magnetic fields.
