Full Characterisation of the Polarisation Primary Beam of the GRAO 32-m Telescope
Theophilus Ansah-Narh, Nia Imara, Benedicta Woode +4
Direction-dependent instrumental polarisation is a major systematic limitation in high-fidelity single-dish radio polarimetry, yet a unified characterisation of beam leakage and th…
The MeerKAT Massive Distant Clusters Survey: a search for diffuse radio emission in 30 massive SZ-selected clusters at
Dakalo G. Phuravhathu, M. Hilton, S. P. Sikhosana +10
We present the results of a search for diffuse radio emission in a uniformly selected sample of 30 of the most massive Sunyaev-Zel'dovich selected galaxy clusters at , provi…
The Ghana Radio Astronomy Observatory
Emmanuel Proven-Adzri, Nia Imara, Theophilus Ansah-Narh +7
The Ghana Radio Astronomy Observatory (GRAO) marks a pivotal advance in African radio astronomy through the successful transformation of a decommissioned 32 m satellite communicati…
The MeerKAT Massive Distant Clusters Survey: detection of diffuse radio emission in galaxy clusters at
Dakalo G. Phuravhathu, M. Hilton, S. P. Sikhosana +11
Diffuse, low surface-brightness radio emission in merging galaxy clusters provides insights into cosmic structure formation, the growth of magnetic fields, and turbulence. This pap…
The MeerKAT Absorption Line Survey Data Release 2: Wideband continuum catalogues and a measurement of the cosmic radio dipole
J. D. Wagenveld, H-R. Klöckner, N. Gupta +18
We present the second data release of the MeerKAT Absorption Line Survey (MALS), consisting of wideband continuum catalogues of 391 pointings observed at L~band. The full wideband…
MeerKAT observations of starburst galaxies and AGNs within the core of XMMXCS J2215.9-1738 at = 1.46
D. Y. Klutse, M. Hilton, I. Heywood +4
We present the first detailed radio study of the galaxy cluster XMMXCS J2215.9-1738 at = 1.46 using MeerKAT -band (1.3 GHz) observations. We combine our radio observation wi…
The MeerKAT Massive Distant Clusters Survey: A Radio Halo in a Massive Galaxy Cluster at z = 1.23
S. P. Sikhosana, M. Hilton, G. Bernardi +9
In the current paradigm, high redshift radio halos are expected to be scarce due to inverse Compton energy losses and redshift dimming, which cause them to be intrinsically faint.…
The MeerKAT Absorption Line Survey (MALS) data release I: Stokes I image catalogs at 1-1.4 GHz
P. P. Deka, N. Gupta, P. Jagannathan +24
The MeerKAT Absorption Line Survey (MALS) has observed 391 telescope pointings at L-band (900 - 1670 MHz) at . We present radio continuum images and a catalog of…
The MeerKAT Absorption Line Survey: Homogeneous continuum catalogues towards a measurement of the cosmic radio dipole
J. D. Wagenveld, H. -R. Klöckner, N. Gupta +21
The number counts of homogeneous samples of radio sources are a tried and true method of probing the large scale structure of the Universe, as most radio sources outside the galact…
PKS1413+135: OH and HI at z = 0.247 with MeerKAT
F. Combes, N. Gupta, S. Muller +13
The BL Lac PKS 1413+135 was observed by the Large Survey Project "MeerKAT Absorption Line Survey" (MALS) in the L-band, at 1139 MHz and 1293-1379 MHz, targeting the HI and OH lines…
Preparing for low surface brightness science with the Vera C. Rubin Observatory: characterisation of tidal features from mock images
G. Martin, A. E. Bazkiaei, M. Spavone +50
Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Ve…
