MIGHTEE: The Host-Galaxy Associated Catalogue of the Radio Sources in MIGHTEE Continuum Data Release 1
C. L. Hale, J. Hamlett, I. H. Whittam +34
Radio continuum surveys provide samples of active galactic nuclei (AGN) and star forming galaxies (SFGs) to high redshifts, free of biases due to dust obscuration. However, radio d…
SuperMIGHTEE : Spectral Ages of Remnant Radio Galaxy Candidates in the XMM-LSS Field
Sushant Dutta, Veeresh Singh, C. H. Ishwara Chandra +8
Remnant radio galaxies, whose lobes are no longer replenished by jets from the active galactic nucleus (AGN), offer key constraints on AGN duty cycles and the timescales of radio j…
Massive star clusters and clumps in the collisional ring galaxy Arp 147
Z. Randriamanakoto, M. Rakototafika, B. Mongwane +2
We conduct a photometric study of star clusters (or knots) in the collisional ring galaxy (CRG) Arp 147 to trace the star formation history across its empty ring. Using HST F450W,…
MIGHTEE: Discovery of a triple-double radio galaxy
Tombo F. Rarivoarinoro, Zara Randriamanakoto, Russ Taylor +8
Triple-double radio galaxies (TDRGs) are amongst the rarest subpopulations of radio galaxies (RGs). They are characterised by three pairs of radio lobes, where each pair of lobes r…
The Jet Paths of Radio AGN and their Cluster Weather
E. Vardoulaki, V. Backöfer, A. Finoguenov +21
We studied bent radio sources within X-ray galaxy groups in the COSMOS and XMM-LSS fields, using radio data from the MeerKAT International GHz Tiered Extragalactic Explorations dat…
