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…

Cosmology from Clustering of Continuum Galaxies

Jacobo Asorey, Catherine L. Hale, Sebastian von Hausegger +6

The distribution of radio continuum galaxies is a useful, fast, and accessible probe of the matter distribution in the Universe, enlightening us about the Universe's initial condit…

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…

MeerKAT observations of the spiral galaxy NGC 2997 in the S band. Detection of high dynamo modes

A. Damas-Segovia, R. Beck, S. A. Mao +18

We seek to exploit the expanded observational range of the MeerKAT radio telescope with the new S-band receivers (2.0-2.8 GHz). To showcase its enhanced capabilities, we conducted…

The MeerKAT Absorption Line Survey (MALS) data release 3: Cold atomic gas associated with the Milky Way

N. Gupta, J. Kerp, S. A. Balashev +15

We present results of a blind search for Galactic HI 21-cm absorption lines toward 19130 radio sources, using 390 pointings of MALS, each pointing centered on a source brighter tha…

The kinematic contribution to the cosmic number count dipole

J. D. Wagenveld, S. von Hausegger, H-R. Klöckner +1

Measurements of the number count dipole with large surveys have shown amplitudes in tension with kinematic predictions based on the observed Doppler dipole of the cosmic microwave…
