Radio surveys of the Milky Way galaxy have transformed our understanding of star formation

and stellar evolution. However, due to strong dependence of “survey cost” on frequency most

large area surveys have so far been carried out at low frequencies (? a few GHz). These surveys

select against dense plasma as the free-free turnover frequency scales directly with electron

density which means that there are significant biases against the detection of the youngest and

densest HII regions, Young Stellar Objects, jets, winds and Planetary Nebulae. Here we describe

the MeerKAT Large Project MeerGAL, which aims to address this issue by making the first sensitive

high frequency, high resolution multi-epoch survey of the Galactic Plane. Together with

its Northern Hemisphere sister project KuGARS (the Ku-band Galactic Reconnaissance Survey),

MeerGAL will revolutionise the study of massive star formation and stellar evolution, Galactic

structure, and variability.
