The presence of diffuse radio sources in galaxy clusters and the recent discovery of polarized signals associated with the tails of a jellyfish galaxy indicates that intra-cluster/…
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…
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…
The Salamander: A case study of the magnetic field and peculiar morphology of G309.8-2.6 through radio polarimetry
Wenhui Jing, Jennifer L. West, Xiaohui Sun +17
Studying the interaction between core-collapse supernova remnants (SNRs) and their surrounding environments is essential to understanding the mechanism for energy transfer to the i…
A Robust Analysis of QU-fitting Behavior for 800-1088 MHz and 1296-1440 MHz
Lindsey Oberhelman, Cameron L. Van Eck, N. M. McClure-Griffiths +9
QU-fitting is a powerful tool for interpreting spectro-polarimetric radio continuum observations by linking them to physical models, enabling estimates of the magnetic fields in, f…
Revealing the magnetization of the intracluster medium of Abell 3581 using background Faraday rotation measures from the POSSUM survey
Affan Khadir, Erik Osinga, Wonki Lee +16
The line-of-sight magnetic field of galaxy clusters can be probed using Faraday rotation measure (RM) data. However, our understanding of cluster magnetism is limited due to the sc…
