Probing Magnetic Fields In and Around Galaxies Near and Far

S. A. Mao, Rainer Beck, Aritra Basu +14

In order to understand the magnetization of galaxies and the role of magnetic fields in feedback processes that govern star formation and galaxy evolution, it is essential to have…

The Multi-phase HI of the Milky Way and Nearby Galaxies

Marc-Antoine Miville-Deschênes, J. R. Dawson, Narendra Nath Patra +30

Atomic hydrogen (HI) is the dominant baryonic component of the interstellar medium (ISM) in Milky Way-like galaxies and the reservoir from which molecular clouds and stars ultimate…

Small-scale Magnetic Fields in the Milky Way and Nearby Galaxies

Yik Ki Ma, Amit Seta, Aritra Basu +13

Magnetic fields in galaxies span decades in physical scale, from the coherent magnetic fields on galactic scales (> kpc) to the random magnetic fields from 100 pc to the resistive…

Imprints of the Neutral Interstellar Medium on Polarized Synchrotron Emission and Faraday Rotation

Minjie Lei, S. E. Clark, Mehrnoosh Tahani +5

The interstellar medium (ISM) is a complex, multiphase medium, where disentangling the distribution of gas and magnetic field structure across different phases remains a considerab…

Magnetised CGM Gas at z~1 revealed by SPICE-RACS

Sunil Malik, S. P. O'Sullivan, A. J. M. Thomson +17

Magnetic fields are expected to permeate the circumgalactic medium (CGM) of galaxies, yet direct constraints at high redshift remain limited by the lack of high-quality Faraday rot…

On the relation between magnetic field strength and gas density in the interstellar medium. II. Density uncertainties and diffuse gas constraints

David Whitworth, Amit Seta, Ralph E. Pudritz +4

The relationship between magnetic field strength and gas density is essential to understand the interstellar medium and star formation. Zeeman measurements in dense atomic and mole…
