A galaxy evolution survey with the MeerKAT radio telescope
The MIGHTEE survey
MIGHTEE (MeerKAT International GHz Tiered Extragalactic Exploration) is an extragalactic radio survey currently being carried out with the South African MeerKAT radio telescope. When complete, MIGHTEE will cover 20 square degrees in four well-studied extragalactic fields to uJy sensitivity at GHz frequencies. The observations provide simultaneous radio continuum, spectral line and polarisation information.
On this website you can find more details about the survey, how to access the data, and publications using MIGHTEE data.

The MIGHTEE survey data, along with the excellent multi-wavelength data already available in these deep fields, will allow a range of science to be achieved. MIGHTEE is designed to significantly enhance our understanding of:
(i) the evolution of active galactic nuclei (AGN) and star-formation activity over cosmic time, as a function of stellar mass and environment, free of dust obscuration;
(ii) the evolution of neutral hydrogen in the Universe and how this neutral gas eventually turns into stars after moving through the molecular phase, and how efficiently this can fuel AGN activity;
(iii) the properties of cosmic magnetic fields and how they evolve in clusters, filaments and galaxies.
MIGHTEE will reach similar depth to the planned SKA all-sky survey, and thus will provide a pilot to the cosmology experiments that will be carried out by the SKA over a much larger survey volume.
