School and society

The department of physics and astronomy offers information to and cooperation with the society in various ways, such as organizing exhibitions and demonstrations to schools and the general public, taking part in various working groups within our respective fields of research and by performing commissioned research and education (see links to the left).

Ask a scientist

It is unfortunalty not possible to ask questions any more, due to a large number of spam posts.

You can still read the old questions.

The presence of organic molecules in the interstellar medium has been known since the 1970’s, but their complexity and the range of environments where they are found continues to increase. In tandem, theories for interstellar chemistry have become more elaborate in order to explain observations. In this talk I will present the evolving theory of complex molecule formation and show recent observational results that might challenge previous paradigms. I will also discuss how molecular isotopic ratios can be used to trace the origin of organic Solar System matter to typical interstellar conditions.

At the present time it is unknown how the U(1) axial anomaly of Quantum Chromodynamics behaves at high temperatures. We therefore want to look for thermal changes of the effects of the anomaly. For example, by studying the properties of the eta-prime meson at high temperatures it would be possible to deduce important information on the axial anomaly, thanks to the deep connection between them. In this thesis the width of the eta-prime as a function of the temperature is studied in the framework of large-N_c Chiral Perturbation Theory, at next-to-leading order, and in the corresponding Resonance Chiral Theory.
