Evidence of a Thick Heliopause Boundary Layer Resulting from Active Magnetic Reconnection with the Interstellar Medium

open access: yesThe Astrophysical Journal
Voyager 1 and 2 data from the vicinity of the heliopause and very local interstellar medium are reexamined to better understand the confounding lack of rotation in the magnetic field ( B -field) across the heliopause observed by both Voyagers, despite ...

Determining the rotation direction in pulsars

open access: yesNature Communications, 2019
Interstellar magnetic fields determined from pulsar polarimetry in the GHz-band may be biased by mechanical-optical rotation in pulsars’ magnetospheres. Here the authors show how observations at sub-GHz frequencies can be used to resolve such a bias and ...

A Tale of Three: Magnetic Fields along the Orion Integral-shaped Filament as Revealed by the JCMT BISTRO Survey

open access: yesThe Astrophysical Journal Letters
As part of the B -fields In Star-forming Region Observations survey, we present James Clerk Maxwell Telescope (JCMT) 850 μ m polarimetric observations toward the Orion integral-shaped filament (ISF) that covers three portions known as OMC-1, OMC-2, and ...

A Catalog of Pulsar X-Ray Filaments

open access: yesThe Astrophysical Journal
We present the first Chandra X-ray Observatory (CXO) catalog of “pulsar X-ray filaments,” or “misaligned outflows.” These are linear, synchrotron-radiating features powered by ultrarelativistic electrons and positrons that escape from bow shock pulsars ...

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). 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.
