The Institute for Astronomy is convening from 31 August to 4 September 2015 a symposium in honour of Fritz Zwicky, the eminent Bulgaria-born Swiss astronomer. The theme of the Symposium is "Confronting Ideas on Galactic Metamorphoses", and will feature 45 of the world's leading extragalactic astronomers and cosmologists.
A precocious black hole
Black holes can be found at the centres of most galaxies. Most have little mass compared with their host galaxy. ETH researchers, however, have discovered a particularly massive black hole, which clearly grew so quickly that the host galaxy was not able to keep pace. This calls into question previous thinking on the co-evolution of galaxies and their central black holes.
Soundproofing with quantum physics
Sebastian Huber and his colleagues show that the road from abstract theory to practical applications needn’t always be very long. Their mechanical implementation of a quantum mechanical phenomenon could soon be used for soundproofing purposes.
