Evidence for inverse Compton scattering in high-redshift Lyman-break galaxies

I. H. Whittam, M. J. Jarvis, E. J. Murphy, Nathan Adams et autres

ABSTRACT Radio continuum emission provides a unique opportunity to study star formation unbiased by dust obscuration. However, if radio observations are to be used to accurately trace star formation to high redshifts, it is crucial that the physical processes that affect the …

The Radio Spectral Energy Distribution and Star Formation Calibration in MIGHTEE-COSMOS Highly Star-forming Galaxies at 1.5 < z < 3.5

F. S. Tabatabaei, Maryam Khademi, M. J. Jarvis, A. R. Taylor et autres

Abstract Studying the radio spectral energy distribution (SED) of distant galaxies is essential for understanding their assembly and evolution over cosmic time. We present rest-frame radio SEDs of a sample of 160 star-forming galaxies at 1.5 < z < 3.5 in the …

Radio continuum spectra of SFGs in the XMM-LSS Field below threshold

E F Ocran, A. R. Taylor, J. M. Stil, M. Vaccari et autres

ABSTRACT This study investigates the radio spectral properties of K$_{S}$-selected star-forming galaxies (SFGs) in the XMM-LSS (multimirror mission large-scale structure) field using extensive multiwavelength data. By employing various diagnostics, SFGs are distinguished from quiescent galaxies and AGN across seven redshift bins ($\rm …

The Polarisation Sky Survey of the Universe’s Magnetism (POSSUM): Science goals and survey description

B. M. Gaensler, G. Heald, N. M. McClure‐Griffiths, C. S. Anderson et autres

Abstract 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 Polarisation Sky Survey of the Universe’s Magnetism (POSSUM), a groundbreaking survey with three primary objectives: (1) …

COMAP Galactic science I: observations of spinning dust emission at 30 GHz in dark clouds surrounding the λ-Orionis H ii region

Stuart Harper, Clive Dickinson Kieran A Cleary, Brandon S. Hensley, Gabriel A. Hoerning et autres

ABSTRACT Anomalous microwave emission (AME) is a major component of Galactic emission in the frequency band 10–60 GHz and is commonly modelled as rapidly rotating spinning dust grains. The photodissociation region (PDR) at the boundary of the $\lambda$-Orionis H ii region has …

MeerKAT discovery of a MIGHTEE Odd Radio Circle

R. P. Norris, B. Koribalski, Catherine Hale, M. J. Jarvis et autres

ABSTRACT We present the discovery of a new Odd Radio Circle (ORC J0219−0505) in 1.2 GHz radio continuum data from the MIGHTEE survey taken with the MeerKAT telescope. The radio-bright host is a massive elliptical galaxy, which shows extended stellar structure, possibly …

A MeerKAT Polarization Survey of Southern Calibration Sources

A. R. Taylor, L. S. Legodi

Abstract We report on full-Stokes L -band observations of 98 MeerKAT calibration sources. Linear polarization is detected in 71 objects above a fractional level of 0.2%. We identify ten sources with strong fractional linear polarization and low Faraday rotation measure that could …
