Multi-wavelength Signatures of Cosmic Rays in the Milky Way

open access: yes, 2017
Cosmic rays (CRs) propagate in the Milky Way and interact with the interstellar medium and magnetic fields. These interactions produce emissions that span the electromagnetic spectrum, and are an invaluable tool for understanding the intensities and ...

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

open access: yesAdvanced Engineering Materials, Volume 27, Issue 22, November 2025.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

The Origin of Filamentary Star Forming Clouds in Magnetised Galaxies

open access: yes, 2018
Observations show that galaxies and their interstellar media are pervaded by strong magnetic fields with energies in the diffuse component being at least comparable to the thermal and even as large or larger than the turbulent energy.

Quasi‐Thermal Noise Spectroscopy in Magnetized Space Plasma: Analysis of Wind/WAVES Measurements in Earth's Magnetosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Quasi‐thermal noise is measured by an electric antenna embedded in a plasma, and is routinely used to obtain a diagnostic of, for example, the plasma density and electron temperature. Its applications have been so far to a large extent aimed at the analysis of unmagnetized plasmas, for which the plasma‐electron cyclotron frequencies ratio is ...

Tomographic Imaging of the Sagittarius Spiral Arm's Magnetic Field Structure

open access: yesThe Astrophysical Journal
The Galactic global magnetic field is thought to play a vital role in shaping Galactic structures such as spiral arms and giant molecular clouds. However, our knowledge of magnetic field structures in the Galactic plane at different distances is limited,

High-mass Starless Clumps: Dynamical State and Correlation between Physical Parameters

open access: yesThe Astrophysical Journal, 2023
In order to study the initial conditions of massive star formation, we have previously built a sample of 463 high-mass starless clumps (HMSCs) across the inner Galactic plane covered by multiple continuum surveys.

Accretion discs, low-mass protostars and planets: probing the impact of magnetic fields on stellar formation

open access: yes, 2008
Whereas the understanding of most phases of stellar evolution made considerable progress throughout the whole of the twentieth century, stellar formation remained rather enigmatic and poorly constrained by observations until about three decades ago, when

Estimating Soft X‐Ray Emission From Uranus's Magnetosheath

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Soft X‐ray emission occurs within planetary magnetosheaths when highly charged solar wind ions undergo charge exchange with neutrals. The emission can provide dynamic views of the magnetosheath and cusps, allowing for investigations of the solar wind interaction with a planetary magnetosphere.

Galactic Magnetic Fields. I. Theoretical Model and Scaling Relations

open access: yesThe Astrophysical Journal
Galactic dynamo models have generally relied on input parameters that are very challenging to constrain. We address this problem by developing a model that uses observable quantities as input: the galaxy rotation curve, the surface densities of the gas ...
