Using early science data for the MIGHTEE project on the MeerKAT radio telescope, a researcher at the University of the Western Cape – with collaborators from eight countries, including four other South African institutions – has analysed over 2 000 galaxies, growing our understanding of the evolution of galaxies over cosmic time.
The part of the sky that was observed for this study is called the COSMOS field and is one area very well studied using many telescopes. The team combined radio astronomy data from the MeerKAT with observations from the VLA radio telescope in the US and the GMRT radio telescope in India. In addition, they used astronomy data science products such as catalogues of galaxies generated with other observations, in particular infra-red.
She forms part of the The MeerKAT International GHz Tiered Extragalactic Exploration project, which seeks to observe the extragalactic sky to explore the cosmic evolution of galaxies. It is one of the MeerKAT Large Survey Projects prioritised by the South African Radio Astronomy Observatory . The findings of the team following this analysis demonstrates that in order for us to gain a deep understanding of all the happenings in galaxies, like the formation of new stars, magnetic fields capturing electrons and other charged particles, and more, any observation is improved with additional data. At different frequencies, or wavelengths of light, different processes dominate.
