MeerKAT discovery of a high-redshift strongly-lensed hydroxyl gigamaser
Thato E. Manamela, Roger P. Deane, Tariq Blecher +3
At low redshifts, hydroxyl megamasers (OHMs) have been shown to trace galaxy mergers, obscured starbursts, high molecular gas densities, and candidate dual supermassive black hole…
The Radio Spectral Energy Distribution and Star Formation Calibration in MIGHTEE-COSMOS Highly Star-Forming Galaxies at 1.5 < z < 3.5
Fatemeh Tabatabaei, Maryam Khademi, Matt J. Jarvis +6
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…
HI asymmetries in spatially resolved SIMBA galaxies
Nadine A. N. Hank, Marc A. W. Verheijen, Sarah-L. Blyth +4
We present a study of the neutral atomic hydrogen (HI) content of spatially resolved, low-redshift galaxies in the SIMBA cosmological simulations. We create synthetic HI data cubes…
The Evolutionary Map of the Universe: A new radio atlas for the southern hemisphere sky

MIGHTEE-HI: The radial acceleration relation with resolved stellar mass measurements
Andreea A. Vărăşteanu, Matt J. Jarvis, Anastasia A. Ponomareva +8
The radial acceleration relation (RAR) is a fundamental relation linking baryonic and dark matter in galaxies by relating the observed acceleration derived from dynamics to the one…
MIGHTEE: exploring the relationship between spectral index, redshift and radio luminosity
Siddhant Pinjarkar, Martin J. Hardcastle, Dharam V. Lal +9
It has been known for many years that there is an apparent trend for the spectral index (α) of radio sources to steepen with redshift z, which has led to attempts to select high-re…
Euclid: A complete Einstein ring in NGC 6505
C. M. O'Riordan, L. J. Oldham, A. Nersesian +195
We report the discovery of a complete Einstein ring around the elliptical galaxy NGC 6505, at . This is the first strong gravitational lens discovered in Euclid and the fi…
Probabilistic and progressive deblended far-infrared and sub-millimetre point source catalogues I. Methodology and first application in the COSMOS field
Lingyu Wang, Antonio La Marca, Fangyou Gao +12
Single-dish far-infrared (far-IR) and sub-millimetre (sub-mm) point source catalogues and their connections with catalogues at other wavelengths are of paramount importance. Howeve…
A MeerKAT Polarization Survey of Southern Calibration Sources
A. R. Taylor, L. S. Legodi
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 sou…
Illuminating the Dark Side of Cosmic Star Formation III: Building the largest homogeneous sample of Radio-Selected Dusty Star-Forming Galaxies in COSMOS with PhoEBO
Fabrizio Gentile, Margherita Talia, Meriem Behiri +14
In the last decades, an increasing scientific interest has been growing in the elusive population of "dark" (i.e. lacking an optical/NIR counterpart) Dusty Star-Forming Galaxies (D…
The LOFAR Two-Metre Sky Survey (LoTSS): VI. Optical identifications for the second data release
M. J. Hardcastle, M. A. Horton, W. L. Williams +49
The second data release of the LOFAR Two-Metre Sky Survey (LoTSS) covers 27% of the northern sky, with a total area of deg. The high angular resolution of LOFAR wi…
Probing magnetic fields in the circumgalactic medium using polarization data from MIGHTEE
K. Böckmann, M. Brüggen, V. Heesen +10
The detection and study of magnetic fields surrounding galaxies is important to understand galaxy evolution since magnetic fields are tracers for dynamical processes in the circumg…
Star formation history of mass-selected galaxies in the ELAIS-N1 Field
E. F. Ocran, M. Vaccari, J. M. Stil +3
We measure the specific star formation rates of \textit{K}-band selected galaxies from the ELAIS-N1 by stacking GMRT data at 610 MHz. We identify a sample of SFGs, spanning $\rm{0.…
A multi-band AGN-SFG classifier for extragalactic radio surveys using machine learning
J. Karsten, L. Wang, B. Margalef-Bentabol +7
Extragalactic radio continuum surveys play an increasingly more important role in galaxy evolution and cosmology studies. While radio galaxies and radio quasars dominate at the bri…
MIGHTEE-HI: The first MeerKAT HI mass function from an untargeted interferometric survey
