Description
MIGHTEE is a galaxy evolution survey currently underway with the MeerKAT radio telescope. Once complete, the survey will cover 20 square degrees in four fields to a depth of ~2 uJy rms/beam at 1.3 GHz, providing a unique combination of depth and breath. Crucially, the MIGHTEE fields have excellent multi-wavelength coverage, enabling a full census of galaxy properties.
I will describe recent work identifying multi-wavelength counterparts for the sources detected in MIGHTEE Early Science data (Whittam et al., 2024) and provide an update on the work currently in progress cross-matching the full MIGHTEE survey. I will then outline the methods used to classify the MIGHTEE sources into different source types (e.g. AGN, SFG) using the extensive multi-wavelength information available, and the insights this gives us into the nature of the faint radio source population (Whittam et al., 2022).
Finally, I will highlight some recent science results from the MIGHTEE continuum survey. This will include the properties of the radio galaxies in the field; in particular, I will discuss whether or not there is evidence for a dichotomy in the accretion rates of high-excitation and low-excitation radio galaxies, and the implications this has for the role radio galaxies play in galaxy evolution.
