Attosecond tracing of electron dynamics in bio-relevant molecules and nanoparticles

Observing electron dynamics in matter on its natural time scale requires attosecond technology. We show how isolated attosecond pulses can be used in combination with phase-stable infrared pulses to track ultrafast charge dynamics in bio-relevant molecules such as amino acids and nucleobases as well as in nanoparticles. Our results open new important perspectives for a future understanding of the role of the electronic motion in the photochemistry of complex molecules.

Who is doing science, who isn`t, and why?

Gender and racial diversity remains very limited in the physical sciences. Why are certain groups so under-represented? Why is it important for the scientific community to be more representative of the population at large? How can diversity be increased? In this talk, I will discuss modern understandings of challenges to diversity, like stereotype threat and unconscious bias. I will also present findings on the status of women and minorities specific to the nuclear physics community.

Gravitational wave astronomy

Gravitational waves have now been detected by the Advanced LIGO detectors. This opens up a new observational window onto many phenomena not previously visible. The collisions of black holes provide ideal laboratories for testing ideas about the behaviour of strong gravitational fields and the nature of black holes. The first observations also begin to constrain formation models of black hole binaries and their properties. Gravitational waves have the potential to detect far more than just black holes. As this new field opens up, I will provide a review of the basic physics and observational techniques employed, discuss some of the latest results and provide a glimpse into what the future of the field of gravitational wave astronomy may bring.

High-resolution terahertz spectroscopy with the Stratospheric Observatory for Infrared Astronomy

Heterodyne spectroscopy is a powerful technique for high-spectral-resolution remote sensing in astronomy and atmospheric research. An emission of particular importance is the atomic oxygen (OI) fine-structure line at 4.7448 THz. This is a major cooling line of the interstellar medium and an important constituent of planetary atmospheres. The German Receiver for Astronomy at Terahertz Frequencies, on board of SOFIA, the Stratospheric Observatory for Infrared Astronomy, is the only spectrometer which can observe this line with MHz spectral resolution. The heterodyne spectrometer is based on a quantum-cascade laser as local oscillator and superconducting hot electron bolometri mixers. The design and the performance of the 4.7-THz spectrometer will be presented. In particular the QCL-based local oscillator will be discussed, because this unique laser system enables observations of the OI line for the first time. Since May 2014, the system has served on 27 successful flights leading to exciting new discoveries, for example OI in the Martian atmosphere. Some of the highlights of these observations will be presented.

Gravity Waves: From the Laboratory to the Atmospheric Surf Zone

Even with present and foreseeable computational capabilities, the spatial resolution of atmospheric weather-forecast and climate models is and will remain insufficient to capture many essential processes. Next to clouds and turbulence, subgrid-scale waves and their parameterization are one of the grand challenges of the field. Here, especially buoyancy-driven gravity waves are in the focus. The talk will give an overview of the fundamental properties and atmospheric impacts of these waves. It will describe the lead issues in their handling in models, and it will discuss recent developments towards their solution,ranging from laboratory experiments over theory to atmospheric modeling.
