Investigating the magnetic field in the inter-cluster filament between Abell 3667 and Abell 3651 with POSSUM
C. Stuardi, S. P. O'Sullivan, L. Rudnick +19
[Abridged abstract] The objective of this study is to measure the magnetic field within the prominent inter-cluster filament recently detected in X-rays by the extended ROentgen Su…
The Large-Scale Structure of the Universe through the SKA lenses
Virginia Cuciti, Surajit Paul, Viral Parekh +11
The large-scale distribution of galaxies in the Universe forms an intricate, interconnected network known as the cosmic web. Cosmological simulations within the standard Lambda-CDM…
The Rapid ASKAP Continuum Survey VII: Spectra and Polarisation In Cutouts of Extragalactic Sources (SPICE-RACS) Second Data Release -- Unveiling the Magnetised Sky
Alec J. M. Thomson, Timothy J. Galvin, Stefan W. Duchesne +18
We present the second data release (DR2) of Spectra and Polarisation in Cutouts of Extragalactic sources from RACS (SPICE-RACS). SPICE-RACS DR2 is derived from the third low-band e…
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…
ASKAP EMU detection of an Odd Radio Circle (ORC) candidate: J094412-751016 (Anglerfish)
M. D. Filipović, Z. J. Smeaton, A. C. Bradley +33
We report diffuse extended radio-continuum emission spatially coinciding with the IR source WISEA J094409.17-751012.8, and a semi-variable star, V687 Carinae. We use 944 MHz radio…
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…
RM-Tools: Software for Analyzing Polarized Radio Spectra
Cameron L. Van Eck, Cormac R. Purcell, Lerato Baidoo +19
Polarization observations using modern radio telescopes cover large numbers of frequency channels over broad bandwidths, and require advanced techniques to extract reliable scienti…
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…
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…
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…
Indications of an offset merger in Abell 3667
Y. Omiya, K. Nakazawa, T. Tamura +13
Abell 3667 is a nearby merging cluster with a prominent cold front and a pair of two bright radio relics. Assuming a head-on merger, the origin of the cold front is often considere…
Interacting Large-Scale Magnetic Fields and Ionised Gas in the W50/SS433 System
J. S. Farnes, B. M. Gaensler, C. Purcell +5
The W50/SS433 system is an unusual Galactic outflow-driven object of debatable origin. We have used the Australia Telescope Compact Array (ATCA) to observe a new 198 pointing mosai…
A high-frequency study of the Sunyaev-Zel'dovich effect morphology in galaxy clusters
D. A. Prokhorov, S. Colafrancesco, T. Akahori +3
High-frequency, high-resolution imaging of the Sunyaev-Zel'dovich (SZ) effect is an important technique to study the complex structures of the atmospheres of merging galaxy cluster…
