Enjoy the photo exhibition in the Old Observatory from home
Two radio telescopes in Green Bank, West Virginia have brought together a few remarkable people. A new photo exhibition in the Old Observatory visitor centre gives an insight into the remote community. Due to the corona crisis, the Observatory is not open to the public. That’s why we’ve selected a few…

Koenraad Schalm Group - String Theory and Experiment
Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

Photographic Traditions in South African Popular Modernities
In the South African context, certain iconic images have been a dominant source for public understandings of historical events. The emphasis given these images tends to overshadow the historical value of other more personal photographic sources – like studio or amateur photography. This project looks…

Blog Post | The Diplomatic Elite, the People at Home and Democratic Renewal
‘Foreign policy’ may seem to the general public to be merely an official response to problems entering the nation from across the border. Yet the political reach of diplomacy has extended, and diplomats will have to find ways to engage more with home citizens, including those who feel sidelined and…

Neutral outflows in high-redshift dusty galaxies
Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…
