The VLA-COSMOS 3 GHz Large Project: Polarised source counts and catalogue

S. Ranchod, S. A. Mao, R. P. Deane +5

The exploration of the faint polarised radio source population is essential for interpreting the nature and evolution of magnetic fields in galaxies. While recent studies have prov…

Variability of Sagittarius A* at 3 GHz on minute-scale with MeerKAT

K. Kaur, I. Rammala-Zitha, A. Basu +21

The supermassive black hole Sagittarius A* (Sgr A*) exhibits temporal and spectral variability across the electromagnetic spectrum. However, variability at radio frequencies below…

A new window into the sub-parsec scale magnetic field in the Milky Way? Unveiling small-scale magneto-ionic structures with Faraday complexity

Yik Ki Ma, Amit Seta, N. M. McClure-Griffiths +9

Radio broadband spectro-polarimetric observations are sensitive to the spatial fluctuations of the Faraday depth (FD) within the telescope beam. Such FD fluctuations are referred t…

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…

A first glimpse at the MeerKAT DEEP2 field at S-band

S. Ranchod, J. D. Wagenveld, H. -R. Klöckner +15

We present the first widefield extragalactic continuum catalogue with the MeerKAT S-band (2.5 GHz), of the radio-selected DEEP2 field. The combined image over the S1 (1.96 - 2.84 G…
