UCT and SKA SA astronomers publish the first HI line (neutral hydrogen) paper based on KAT-7 observations

A team composed of Prof C. Carignan, postdoctoral fellows D. Lucero and K. Hess, PhD students B. Frank and T. Randriamampandry from UCT and of SKA SA scientists S. Goedhart and S. Passmoor have published, in the well-known Astronomical Journal, the first scientific publication on neutral hydrogen (HI) using KAT-7 observations. The astronomers pointed the telescope towards a galaxy called NGC 3109 – a spiral galaxy, about 4.3 million light-years away from Earth, located in the constellation of Hydra. They have accumulated more than 120 hours of observations with the aim of studying its dark matter content.
