Virgo Filaments VII: MeerKAT HI-imaging of the VirgoIII filament

M. Ramatsoku, G. Nagaraj, P. Jablonka +11

We present MeerKAT HI observations of galaxies in the nearby Virgo III filament. At a median distance of Mpc, the filament extends over Mpc across deg…

Neutral Hydrogen in the Shapley Supercluster Core I: Environmental Effects on Gas Content and Galaxy Evolution

L. Gwebushe, T. Venturi, P. Merluzzi +5

We study the atomic Hydrogen (HI) content of galaxies in the core of the Shapley Supercluster (SSC) at <z> ~ 0.048, using observations from the MeerKAT Galaxy Cluster Legacy Survey…

The shocking features in the closest rich galaxy cluster Norma

Chong Ge, Ming Sun, Mpati Ramatsoku +2

The merger shocks generated by the collision of galaxy clusters elevate the pressure within the intracluster medium, significantly influencing the evolution of embedded cluster gal…

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…

MIGHTEE: The evolving radio luminosity functions of star-forming galaxies to and the cosmic history of star formation

Nijin J. Thykkathu, Matt J. Jarvis, Imogen H. Whittam +9

A key question in extragalactic astronomy is how the star-formation rate density (SFRD) evolves over cosmic time. A powerful way of addressing this question is using radio-continuu…
