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 ...

Interstellar Magnetic Fields: An Observational Perspective

open access: yes, 1989
Abstract: Chapter 1 establishes the plausibility of “magnetic molecular clouds.” We show that the empirically known relations between spectral line width, density, and cloud size can be derived from a virial equilibrium model where gravity is balanced by the sum of magnetic and pressure support.

Magnetic Fields in the Eos Cloud: Dynamically Important Fields in the Interface between Atomic and Molecular Gas

open access: yesThe Astrophysical Journal
The recently discovered Eos molecular cloud is a CO-dark, low-density cloud located at a distance of approximately 94 pc from the Sun which does not appear to have formed stars at any point in its history.

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 ...

Magnetic Field of a Ring-like Molecular Cloud

open access: yesThe Astronomical Journal
We present a detailed study of the magnetic field structure in the G111 molecular cloud, a ring-like filamentary cloud within the NGC 7538 region. Our analysis combines multiwavelength polarization data and molecular-line observations to investigate the ...

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 ...
