Synthetic shadow images of Sgr A* for a Kerr black hole (left) and a non-rotating dilaton black hole (right). Moving the slider downwards reveals the “before” images, whilst moving it upwards reveals the “after” images. For both black holes the “before” panels refer to the image produced by the general-relativistic MHD simulations, whilst the “after” panels refer to the image reconstructed after realistic observational conditions are considered.







An image from my research modelling the appearance of Sagittarius A* has appeared in the following article in the Frankfurter Allgemeine Zeitung (FAZ) newspaper (11th of April 2017) and a digital copy of the article may be found here.
