How Fast Is Ultrafast?

In a recent episode of the podcast Bridge the Gap, Tommaso Mazzocchi and Daniel Werner, two graduate physics students, interviewed Peter Puschnig about ultrafast spectroscopy and his current research. The conversation spans fundamental quantum-mechanical concepts and leads up to state-of-the-art methods for observing electronic dynamics in real time. The episode is titled “How fast is ultrafast spectroscopy?” and is aimed at students and anyone interested in modern physics research.

Accelerated communication with the Kanzelhöhe: solar observatory moves closer to the university

From mid-December, the train journey from Graz to Villach will be reduced to just over an hour. This faster railway connection through the Koralm Tunnel will also bring the Kanzelhöhe Observatory for Solar and Environmental Research closer. Although this unique research station at 1500 metres above sea level is located on the Carinthian Gerlitzen, it has been part of the University of Graz for more than 75 years.
