The authors report a search in cold, quiescent and in hot core type interstellar mol. clouds for the small cyclic mol. oxiranecarbonitrile (C3H3NO), which was suggested as a precursor of important prebiotic mols. The authors detd. upper limits to the colum ...
Neutral atomic hydrogen (HI) and molecular hydrogen (H2) play a primordial role in the cosmic evolution of galaxies. However, little is known about the co-evolution of these two gas phases. This discrepancy and the design of future telescopes like the SKA ...
The excitation of the Rydberg states is used to study the nonpolar solvation dynamics in supercrit. fluids (SCFs). The system NO in supercrit. Ar serves as the model system. First, the steady-state, absorption and fluorescence spectra of the NO X 2P-A 2S+( ...
During the past five years, delay-Doppler radar has become the primary technique for studying the structure of Earth-crossing asteroids. None of these objects has yet been visited by spacecraft, so ground-truth test cases are lacking. A laboratory system i ...
Radio interferometry probes astrophysical signals through incomplete and noisy Fourier measurements. The theory of compressed sensing demonstrates that such measurements may actually suffice for accurate reconstruction of the signals. We propose new generi ...
In the framework of the INTERREG IIIb NWE project « Strategies and Actions for Flood Risk Management » (SAFER), a detailed streambank erosion hazard model applicable to long river reaches has been developed. Streambank erosion has caused significant damage ...
This paper presents a chronological overview of the developments in interpolation theory, from the earliest times to the present date. It brings out the connections between the results obtained in different ages, thereby putting the techniques currently us ...
Radio interferometry probes astrophysical signals through incomplete and noisy Fourier measurements. The theory of compressed sensing demonstrates that such measurements may actually suffice for accurate reconstruction of sparse or compressible signals. We ...
We experimentally and theoretically study the controlled coupling between localized and delocalized surface plasmon modes supported by a multilayer metallic photonic crystal slab. The model system to visualize the interaction phenomena consists of a gold n ...
How structures of various scales formed and evolved from the early Universe up to present time is a fundamental question of astrophysical cosmology. EDGE (Piro et al., 2007) will trace the cosmic history of the baryons from the early generations of massive ...
