Towards the exploration of astrophysical datacubes through volumetric rendering within CARTA
Ixaka Labadie-García, Adrianna Pińska, Angus Comrie +5
Data products from astrophysical observations may contain three or more dimensions: most commonly two spatial dimensions and a third spectral dimension, and possibly additional axe…
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
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…
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…
A MeerKAT survey of nearby dwarf novae: I. New detections
J. Kersten, E. Körding, P. A. Woudt +8
A program to search for radio emission from dwarf-novae-type cataclysmic variables was conducted with the South African MeerKAT radio telescope. The dwarf novae RU Pegasi, V426 Oph…
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…
A Multi-Wavelength Characterization of the Obscuring Medium at the Center of NGC 6300
D. Sengupta, N. Torres-Albà, A. Pizzetti +9
Most of the super-massive black holes in the Universe accrete material in an obscured phase. While it is commonly accepted that the "dusty torus" is responsible for the nuclear obs…
Finding radio transients with anomaly detection and active learning based on volunteer classifications
Alex Andersson, Chris Lintott, Rob Fender +9
In this work we explore the applicability of unsupervised machine learning algorithms to finding radio transients. Facilities such as the Square Kilometre Array (SKA) will provide…
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.…
