- Markus Boettcher
I review the optical follow-up programme on high energy (X-ray and $\gamma$-ray) transient and variable sources, focusing on results from the Southern African Large Telescope (SALT) but also including supporting observations using SAAO and other facilities. This programme began in 2016 and various classes of objects have been observed, including $\gamma$-ray flaring blazars, high and low mass...
The South African Radio Astronomy Observatory (SARAO) operates and is host to several radio telescopes, including the 64-dish MeerKAT Array. I'll give a brief overview of SARAO and its activities. The MeerKAT telescope, inaugurated in 2018, and still undergoing commissioning of advanced capabilities, has already proven its worth in the scientific arena. A brief overview of the MeerKAT...
On 12 May 2022, the Event Horizon Telescope Collaboration published the first horizon-scale images of Sagittarius A*, the 4-million Solar mass black hole in the center of our Milky Way. These images were the result of a 230 GHz VLBI observing campaign with the Event Horizon Telescope in 2017, including extensive multi-wavelength coverage from other observatories. In this talk, I will give an...
