The Astrophysical JournalWe study the properties of sub-Alfvénic magnetohydrodynamic (MHD) turbulence, i.e., turbulence with Alfvén mach number M _A = V _L / V _A < 1, where V _L is the velocity at the injection scale and V _A is the Alfvén velocity.

The Astrophysical JournalVoyager 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 ...

Most-likely DCF Estimates of Magnetic Field Strength
The Astrophysical JournalThe Davis–Chandrasekhar–Fermi (DCF) method is widely used to evaluate magnetic fields in star-forming regions. Yet it remains unclear how well DCF equations estimate the mean plane-of-the-sky field strength in a map region. To address this question, five

The Huge Magnetic Toroids in the Milky Way Halo
The Astrophysical JournalThe magnetic fields in our Milky Way can be revealed by the distribution of Faraday rotation measures (RMs) of radio sources behind the Galaxy and of radio pulsars inside the Galaxy. Based on the antisymmetry of the Faraday sky in the inner Galaxy to the

Magnetic Fields in the Interstellar Medium
, 2017 The interstellar medium – the space between the stars in our Galaxy – is multiphase, turbulent, and magnetic. Magnetism in the interstellar medium is difficult to observe and to simulate, and the study of interstellar magnetic fields is riddled with open questions. In this Thesis we make progress in several important areas.

The Astrophysical JournalPulsar halos are produced by electrons and positrons diffusing in the interstellar medium around their parent pulsar wind nebulae. Recent observations by High Altitude Water Cherenkov Observatory and Large High Altitude Air Shower Observatory have ...

When Magnetic Fields Sculpt the Sky: The Riegel–Crutcher Cloud in Optical Polarization
The Astrophysical JournalFilamentary structures are ubiquitous in the interstellar medium, yet the extent to which magnetic fields influence the morphology of cold atomic gas remains an open question.

Infrared polarimetry and the interstellar magnetic field
The Astrophysical Journal, 1989 Une bonne correlation entre la polarisation interstellaire et l'extinction interstellaire est trouvee a 2,2 μm pour toutes les lignes de visee. Un modele de champ magnetique interstellaire est presente, et montre qu'une contribution egale de la composante uniforme et de la composante aleatoire reproduit bien les ...

A Catalog of Pulsar X-Ray Filaments
The Astrophysical JournalWe 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 ...

The Astrophysical JournalThe 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.
