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…

Magnetic Fields in the Shapley Supercluster Core with POSSUM: Challenging Model Predictions

D. Alonso-López, S. P. O'Sullivan, A. Bonafede +18

Faraday Rotation Measure (RM) Grids provide a sensitive means to trace magnetized plasma across a wide range of cosmic environments. We study the RM signal from the Shapley Supercl…

A Catalog of Galactic Supernova Remnants and Supernova Remnant Candidates from the EMU/POSSUM Radio Sky Surveys. I

B. D. Ball, R. Kothes, E. Rosolowsky +16

We use data from the EMU (Evolutionary Map of the Universe) and POSSUM (Polarization Sky Survey of the Universe's Magnetism) radio southern sky surveys, conducted with the Australi…

The Polarisation Sky Survey of the Universe's Magnetism (POSSUM): Science Goals and Survey Description

B. M. Gaensler, G. H. Heald, N. M. McClure-Griffiths +57

The Australian SKA Pathfinder (ASKAP) offers powerful new capabilities for studying the polarised and magnetised Universe at radio wavelengths. In this paper, we introduce the Pola…

The Evolutionary Map of the Universe: A new radio atlas for the southern hemisphere sky

A. M. Hopkins, A. Kapinska, J. Marvil +70

We present the Evolutionary Map of the Universe (EMU) survey conducted with the Australian Square Kilometre Array Pathfinder (ASKAP). EMU aims to deliver the touchstone radio atlas…

Relighting the fire in Hickson Compact Group (HCG) 15: magnetised fossil plasma revealed by the SKA Pathfinders & Precursors

C. J. Riseley, T. Vernstrom, L. Lovisari +26

In the context of the life cycle and evolution of active galactic nuclei (AGN), the environment plays an important role. In particular, the over-dense environments of galaxy groups…
