Multi-wavelength Signatures of Cosmic Rays in the Milky Way
, 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 ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract The Laschamps geomagnetic excursion (≈41,000 years BP) was a period of significant weakening and incomplete reversal of the Earth's magnetic field. The weakening substantially reduced geomagnetic shielding against cosmic rays (CRs), which contribute to phenomena at Earth, such as cosmogenic isotope production, and atmospheric ionisation and ...

Tomographic Imaging of the Sagittarius Spiral Arm's Magnetic Field Structure
The Astrophysical JournalThe 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
The 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.

Heat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

Galactic Magnetic Fields. I. Theoretical Model and Scaling Relations
The Astrophysical JournalGalactic 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 ...

Detection of microgauss coherent magnetic fields in a galaxy five billion years ago
, 2017 Magnetic fields play a pivotal role in the physics of interstellar medium in galaxies, but there are few observational constraints on how they evolve across cosmic time.

Probing interstellar magnetic fields with Supernova remnants [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractAs Supernova remnants expand, their shock waves are freezing in and compressing the magnetic field lines they encounter; consequently we can use Supernova remnants as magnifying glasses for their ambient magnetic fields. We will describe a simple model to determine emission, polarization, and rotation measure characteristics of adiabatically ...
